Hank Pym

"This is your chance. To earn that look in your daughter's eyes. To become the hero that she already thinks you are. It's not about saving our world, it's about saving theirs. Scott, I need you to be the Ant-Man."

- Hank Pym to Scott Lang

Doctor Henry Jonathan "Hank" Pym is an entomologist and physicist who developed the Ant-Man Suit after discovering the Pym Particles. For a time, he worked for S.H.I.E.L.D. as a consultant and became the first Ant-Man. Later he formed his own company, Pym Technologies, and passed the title of Ant-Man down to Scott Lang when his own former protégé Darren Cross replicated the Pym Particle and attempted to sell his technology, the new Yellowjacket Suit, to several buyers, including HYDRA and the Ten Rings.

Thanks to his recruitment of Lang to stop Cross, and Lang’s successful escape from the Quantum Realm, Pym came to terms with losing his wife Janet van Dyne to the said realm years earlier, because he thought she could be alive in there. For two years since 2016, Pym developed a Quantum Tunnel capable of traversing across the Quantum Realm. In 2018, Pym and his daughter Hope van Dyne initiated a plan to rescue her from the Quantum Realm, but this proved problematic when Ghost and his former colleague Bill Foster had conflicting ulterior motives. Nonetheless, Pym was successful in rescuing his wife with Lang and Van Dyne's help. Not long after, Pym and his family became three of the trillions of victims in the Snap.

It wasn't until 2023 that Pym was resurrected in the Blip. Despite the tension between him and the Stark family, Pym was in attendance at Tony Stark's funeral after he sacrificed his life to wipe out the time-displaced Thanos and his armies.

Military Career
"May I remind you, Dr. Pym, that you’re a soldier..." "I’m a scientist."

- Mitchell Carson and Hank Pym A young promising scientist, Hank Pym trained in the United States Army before he was recruited by S.H.I.E.L.D. to work as a consultant. He eventually discovered a type of particles that could shorten the distance between an object's molecules, effectively reducing its size while maintaining its mass. Utilizing the newly-discovered particles, Pym developed a suit that could shrink a human being to the size of an ant, yet maintain his original strength and resilience.

Creating the Suit
Pym also developed the EMP Communication Device, a device that allowed him to telepathically communicate with ants. Through concentration, he could manipulate and control ants into doing what he wished. At first he found it difficult to control s, but eventually mastered it. Since then, he went around the world performing missions for S.H.I.E.L.D., with this revolutionary technology.

Project G.O.L.I.A.T.H.
"I was partners with Hank on a project called G.O.L.I.A.T.H.."

- Bill Foster

Working for S.H.I.E.L.D., Pym cooperated with Doctor Bill Foster in Project G.O.L.I.A.T.H., where they experimented with the Pym Particles in order to expand their body mass. Tests showed postive result, making Foster able to achieve a maximum height of 21 feet. However, disagreement between Pym and Foster grew what caused him to abandon the project.

Mission in Berlin
"Sometimes you won't know what you're working with until you're in the moment... So you have to improvise." "Okay... This I was not expecting."

- Peggy Carter and Hank Pym

In 1987, a group of radicals in the Soviet-controlled East Berlin discovered a piece of an old HYDRA technology; the leaders of S.H.I.E.L.D. decided to send an agent to Berlin and stop them from reverse-engineering it. Howard Stark confronted Pym about giving S.H.I.E.L.D. his Ant-Man Suit. However, Pym was unwilling to give his suit to anyone else, so Agent Peggy Carter had to convince him to go to Berlin personally. To see if the suit actually worked, she fired a few bullets at Pym, and he became small like an ant in the blink of an eye.

In Berlin, Pym successfully snuck past the Berlin Wall only to be spotted by a guard dog. Pym managed to escape by jumping on an anti-personnel device which then fired him to safety. He made his way into the radicals' headquarters by controlling a flying ant. He discovered that the group had not even built the device yet. He soon found a group of HYDRA scientists torturing a prisoner. Pym intervened and defeated them, liberating the prisoner in the process. Back at the S.H.I.E.L.D. Headquarters, Stark thanked Pym and told him that was his last mission but Pym refused, realizing there were more problems in the world. Still only trusting himself to wear the Ant-Man Suit, Pym decided to continue to do field missions.

Tragic Loss
"I knew I had to shrink between the molecules to disarm the missile, but my regulator had sustained too much damage. Your mother, she didn't hesitate."

- Hank Pym to Hope van Dyne

During that same year, Pym and his partner and wife, Janet van Dyne, also known as the Wasp, were called upon to intercept a Soviet missile that had been launched against the United States of America; however, they were unable to break through the missile to disable it. Pym attempted to shrink into subatomic size, but his suit had sustained heavy damage and could not. This prompted van Dyne to disable her own suit's safety measures and shrink into subatomic size in order to penetrate the missile's titanium shell. Though managing to disable the missile, she disappeared into the subatomic Quantum Realm and was lost, seemingly forever. Pym would spend the next ten years studying the Quantum Realm in hopes of finding his lost wife, to the detriment to his relationship with his daughter, Hope, whom he sent away to a boarding school.

Quitting S.H.I.E.L.D.
"I formally tender my resignation." "We don’t accept it. Formally. Hank, we need you. The Pym Particle is a miracle. Please, don’t let your past determine the future." "As long as I am alive, nobody will ever get that formula."

- Hank Pym and Howard Stark

The disappearance of Janet traumatized Hank, causing him to quit S.H.I.E.L.D. and hang up his suit. Pym traveled to the under-construction Triskelion to meet with Peggy Carter, Howard Stark and Mitchell Carson, accusing them of attempting to steal his Pym Particles, which he deemed too dangerous. When Carson insulted Pym over his wife's death, Pym slammed his head onto the desk. Pym assured the board that as long as he was alive, no one would ever be allowed to get his formula. Knowing the danger that his own technology possessed, Pym then returned to his home where he took his Ant-Man Suit and placed it in his safe. As Pym took one final look at the suit, he locked the door of the safe before sealing it shut with the intent to never again wear his own suit and become the Ant-Man again. For the next twenty years, the suit remained locked away from Howard Stark and S.H.I.E.L.D., with the power of the Pym Particles being hidden from the world for its own protection as Pym viewed it, believing it to now be far too dangerous if it fell into the wrong hands.

Losing the Company
"I took on a young protégé called Darren Cross." "Darren Cross. He’s a big deal." "But before he was a big deal he was my assistant."

- Hank Pym and Scott Lang

Having left S.H.I.E.L.D., Pym created his own company named Pym Technologies. Although he continued to bury the research into the Pym Particles and the Ant-Man Suit, Pym Technologies was a huge success, earning Pym billions and making him one of the richest men in the world. As he continued to take an active part in the company, Pym hired a young assistant named Darren Cross and trained him.

Seeing the potential in the young man, Pym took him under his wing and, training him as his protege, Cross developed a strong connection with Pym and found a fascination with the legend of the Ant-Man, although Pym always dismissed the stories as an urban legend. When Pym got older, a vote was taken on whether or not he should continue being a part of the company. The vote came down to Hope van Dyne, who voted her father out of the company, allowing Darren Cross to become the new CEO. Over the next few years, Pym rarely, if ever, returned to Pym Technologies and instead lived as a recluse in his mansion, still continuing his experiments to try to understand the Quantum Realm. At some point, Pym was contacted by his estranged daughter, Hope van Dyne, who told him that Cross was trying to replicate the Ant-Man Suit and sell it to other parties. Knowing of the dangers of Cross trying to replicate his work, Pym agreed to help her.

Seeing the Yellowjacket Suit
"Darren, there’s a reason that I buried these secrets." "So you finally admit it. We could’ve done this together, Hank. But you ruined that. That's why you're the past and I'm the future."

- Hank Pym and Darren Cross

Pym was invited to a presentation at Pym Technologies and, much to the surprise of everyone, Pym did indeed attend, suspecting that Cross will show how far he had managed to develop the Pym Particle technology for his own. As he drove into the facility, the security guard could not hold back his shock upon seeing his arrival, to which Pym told him that he was not dead as some seemingly believed. When Pym entered the building, the next security guard asked to see his I.D., to which Pym simply pointed to the portrait of himself hanging on the wall. As he explored the building for the first time in decades, Pym was greeted by Hope van Dyne, who refused to call him dad despite his wishes. Upon seeing Pym's arrival, Darren Cross greeted him warmly and welcomed him back. As he walked to the presentation, Pym was greeted by Mitchell Carson who asked how retirement was, but Pym sarcastically rebuffed him by dryly asking how his face was, reminding him of what happened last time they saw each other in 1989, causing Carson to quickly walk away with barely repressed anger. Lead to the presentation room, Pym took not of a diorama of Pym Technologies; however, the logo had been replaced with a new one saying Cross Technologies, which Cross noticed and gave him a mocking smile, causing him to seethe with anger. Cross began his presentation and discussed the history of the Ant-Man Suit as Pym watched with a scowl on his face and when Cross asked him to remind everyone his repeated insistence that the stories were simply an urban legend, Pym only barely managed to repress his anger and stated that it was just a tall tale. Cross then revealed that it was a legend no longer as he finally was near completion on his own version of the technology which he was calling the Yellowjacket Suit, a battle armor designed to shrink and cause massive damage to an enemy force. Pym was left horrified as the video presentation demonstrated how, despite his best efforts to destroy the research, his Pym Particle technology was now being used to fuel weapons of war which could destroy the world. Only one guest questioned the presentation, noting that it was simply a suit and that as a weapon it could be highly dangerous if it were to fall into enemy hands. After the investors had left, Pym confronted Cross and attempted to convince him that the technology was too dangerous; however, Cross was too caught up in the fact that Pym had finally confessed that the technology had existed and Pym had been lying to him. Despite Pym's best efforts to convince Cross that there were reasons why he had attempted to bury these designs all those years ago, Cross refused to listen, instead informing Pym that they could have made this breakthrough together, before leaving to speak to Carson. Once Cross had left, Pym spoke to Hope van Dyne and they discussed how close Cross was to completing his work on the Pym Particles, with van Dyne noting that he had not yet mastered transforming live subjects. Although van Dyne continued to push the idea that she should be given the Ant-Man Suit and allowed to complete the mission, Pym refused as he did not wish to lose her like he had lost Janet van Dyne. He then informed her that he had found a guy who could help their mission to stop Cross.

Testing a Thief
"You don’t have many options right now. Quite frankly, neither do I. Why do you think I let you steal that suit in the first place?"

- Hank Pym to Scott Lang

Having heard of Scott Lang's prison sentence for breaking into the Vistacorp Headquarters hacking their systems and paying back the money VistaCorp had been stealing from their users, Pym became fascinated by Lang's selfless act to help people being cheated by the company and his skill in hacking one of the most advanced security systems in the world. Believing he was the right man for the job, Pym decided to test Lang's skills by allowing him to learn about the whereabouts of his Ant-Man Suit within his safe. Pym watched from CCTV and hidden cameras as Lang broke into his home after disabling his security. Upon finding Pym's safe, Lang used his quick thinking to find and copy Pym's fingerprint from a kitchen knife to get through the first door before freezing the second safe from the inside, causing it to break open. Once inside, Lang found the Ant-Man Suit and was horrified to not find any money or other valuables with it. Seeing no other choice of how to make money, Lang took the suit and escaped while Pym watched.

Trial by Fire
"It's a trial by fire, Scott. Or in your case, water."

- Hank Pym to Scott Lang

As Scott Lang studied the Ant-Man Suit, he tried it on and accidentally activated the suit's shrinking abilities, becoming trapped in his bath. Hank Pym used the intercom inside the suit's helmet to communicate with Lang, telling him he was going to have to test out the suit. Pym watched from his hidden cameras as Lang was thrown out of the bath when his flatmate Luis turned on the bathwater. Lang was thrown from room to room in the flat before finally being tossed from the window when he was finally able to return to normal size.

Breaking Lang Free
"Second chances don’t come around all that much. So next time you think you might see one, I suggest you take a real close look at it."

- Hank Pym to Scott Lang

With Scott Lang back in jail after being caught by police sent by Hope van Dyne, Pym went to the jail pretending to be Lang's lawyer and met him there, using his Ants to cover up the security cameras. Once they introduced each other Pym explained that he was willing to give Lang a shot at redemption if he assisted him in his mission to stop Darren Cross. To this end, Pym sent a team of ants into Lang's jail cell to deliver the Ant-Man Suit to him, which he used to escape.

Explaining the Mission
"My days of breaking into places and stealing shit are over! What do you want me to do?" "I want you to break into a place and steal some shit." "Makes sense."

- Scott Lang and Hank Pym

Pym brought Scott Lang back into his home and explained to him why he had been brought into their plan. While Hope van Dyne continued to question why he was there, Lang understandably had many questions, and Pym explained how he was able to train his Ants by using high frequencies to communicate with them, demonstrating by having the ants bring sugar into Lang's cup of tea, before explaining in more detail why he needed Lang to assist him in stopping Darren Cross' plan. Taking Lang into the basement, Pym showed him what he and van Dyne had been planning for the last few months in their attempt to stop Darren Cross from building an army with the Yellowjacket Suit. Lang remained skeptical and suggested that they call the Avengers to help them in their mission, but Pym dismissed this idea as he claimed he had spent much of his early career ensuring that Howard Stark did not get ahold of this technology, so he would not allow Tony Stark to use it either. When Lang remained unconvinced that he was the right man for the job, Pym gave a speech about how they were not doing this mission to save themselves, but to save their children and earn the respect in Cassie Lang's eyes, which Lang noted as a great speech before agreeing to help them. Pym trained Scott Lang in learning to use and control the suit in such a way that he and it became one and the same, he demonstrated this by having Lang attempt to jump through the gap in a keyhole and turn back to normal size on the other side. Lang attempted this time after time but without a true understanding of the suit, he constantly failed and crashed into the door. Eventually, after much practice, Lang succeeded and jumped through the keyhole, only to crash into the wall on the other side, although he still claimed to have nailed the attempt. The next stage of the training involved teaching Lang how to communicate and use the various forms of Ants at his disposal. To do this, Pym sent Lang into the ant's tunnels in his garden to meet them; these included Bullet Ants, Carpenter Ants, Crazy Ants and Fire Ants, all of which had their various uses and skills for their mission. However, when Lang would go into the tunnels, the size and numbers of the ants would often surprise and alarm him, causing him to regrow into his normal size, much to his embarrassment and Pym's annoyance. Pym also tasked Hope van Dyne in teaching Lang how to fight in the Ant-Man Suit. Hank Pym found Scott Lang in his study one afternoon fiddling with the Ant-Man Suit's generator on the belt, claiming that he believed he could improve it. Pym told him to stop as any change to the generator would be highly dangerous as if the generator became unstable then the user could potentially fall into the Quantum Realm where they could be lost to time and space forever. Seeing Pym's fear of the dangers that this involved, Lang agreed not to fiddle with the suit any longer.

Explaining the Truth
"Your mom died a hero. And I spent the next ten years trying to learn all I could about the Quantum Realm." "You were trying to bring her back." "But all I learned was we know nothing."

- Hank Pym and Hope van Dyne

Despite Pym's best efforts, Scott Lang continued to struggle to master how to communicate with the Ants. As he became more frustrated, Hope van Dyne ordered him to commit to the attempt. To demonstrate that she should be the one going on the mission, van Dyne communicated with the ants and made them place the sugar in the tea before bringing in a small army to do the same. Pym yelled at van Dyne to stop and she stormed out of the house. When Lang and van Dyne returned to the house after taking a moment to continue their training, Pym made the choice he had been avoiding for decades. He explained to Van Dyne the details of the final mission he had undertaken with her mother Janet van Dyne, telling her of how she had sacrificed herself to save millions of lives and been lost in the Quantum Realm which Pym had spent the next few decades trying to understand. Van Dyne hugged her father and their relationship finally began to rebuild once again, although the moment was somewhat ruined by Lang's comments.

Duel at New Avengers Facility
"Uh, guys, we might have a problem. Hank, didn’t you say this was some old warehouse? It’s not! You son of a bitch!" "Scott, get out of there." "Abort! Abort now. He's going to lose the suit!"

- Scott Lang, Hope van Dyne and Hank Pym

To put his training to the test, Pym organized a mission in which Scott Lang would be sent to steal a device from one of Howard Stark's old facilities which would help them in their mission by disrupting transmissions from Pym Technologies, allowing them to sneak inside without Darren Cross' security team being aware of their presence. As Lang rode Ant-thony to the facility while Pym and Hope van Dyne watched from the mansion, Lang quickly reported that the facility had become the New Avengers Facility which was guarded by the Avengers. Realizing their mistake, Hope van Dyne ordered Lang to abandon the mission, but he refused. Once Lang landed, he was confronted by Falcon who attempted to stop him, causing them to fight. Lang was just able to overpower and defeat the Falcon before escaping the facility with the device.

Confronted by Darren Cross
"All those years ago, you picked me. What did you see?" "I saw myself." "Then why did you push me away?" "Because I saw too much of myself."

- Darren Cross and Hank Pym

Going through the house, Pym discovered that Darren Cross had seemingly broken into his house and was close to discovering their plans. Pym calmly spoke to Cross and as they spoke Scott Lang used the Ants to hide the plans. Cross invited Pym to join him at the presentation for his Yellowjacket Suit, as he claimed that he wanted his mentor to be beside him at his greatest moment of achievement. The two had a conversation about why Pym picked Cross as his mentor in the first place. Pym agreed and Cross left the house, seemingly having not found out about Pym's plans. Pym discussed if Cross had known that Hope van Dyne was in the house. The question was seemingly answered when van Dyne was called by Cross, who ordered her to increase security at Pym Technologies, leaving the team with seemingly no hope of completing their mission. Scott Lang suggested that they could still complete their plan if they used the water pipes and increased their team to include people so as to complete other tasks. Realizing that Lang intended to hire his former team of Luis, Dave and Kurt, Pym attempted to argue.

Building the Team
"Oh we can handle it, we’re professionals." "You’ll forgive us if we’re not instilled with confidence." "Wait, everybody. Just kick back and relax a little bit, man. We know our business."

- Luis, Hank Pym and Dave

Much to Hank Pym's annoyance, Luis, Kurt and Dave were brought into his home and invited to join their team. The three seemed mostly surprised to have been welcomed back into the house after robbing it just a few days earlier. Scott Lang came into the room dressed in the Ant-Man Suit, scaring Luis out of the room when he demonstrated its shrinking abilities. They worked out the new plan involving Luis, Kurt and Dave, giving them each individual tasks to complete, including allowing Luis to pose as a security guard at Pym Technologies. Pym remained unconvinced by their lack of professionalism and noted that they were doomed to fail with their help. Not helping Pym's confidence was Luis' instance to improvise during his mission by whistling as he believed it would help him blend in as a security guard, despite Lang and Pym's objections to the idea.

Arriving the Pym Technologies
"I gotta hand it to you, Darren, you really did it." "And you only know the half of it, Hank."

- Hank Pym and Darren Cross

The plan went underway and Pym arrived at Pym Technologies to meet with Darren Cross. Before Pym could enter however, he was stopped by Jim Paxton and Gale, who wished to question Pym over his relationship with Scott Lang. Pym tried to talk his way out of the situation, telling the men that if he did not get inside the building, a lot of people were going to die. Before he could be arrested however, Dave stole the officer's police car and drove away, forcing them to give chase. Once inside the facility, Pym was greeted by Darren Cross, who seemed delighted that Pym had turned up. Cross invited Pym and Hope van Dyne into the demonstration room for a private discussion on Cross' achievements. All while they spoke, Scott Lang made his way through the water line after Luis successfully opened the valves. Lang only needed to wait for Kurt to disable the security systems for a moment so he could steal the Yellowjacket Suit and escape.

Darren Cross' Revenge
"Don’t do this. If you sell to these men, it’s going to be chaos." "I already have, and for twice the price, thanks to you. It’s not easy to successfully infiltrate an Avengers facility. Thankfully, word travels fast."

- Hank Pym and Darren Cross

Darren Cross welcomed Pym and Hope van Dyne and walked them into the demonstration room, where his men immediately held them at gunpoint, revealing that he had learnt of their scheme. Cross trapped Scott Lang and took the Yellowjacket Suit before welcoming Mitchell Carson into the room and introduced him as the representative from HYDRA; Pym punched Cross in the face and told him to reconsider selling his designs to the terrorist organizations. Cross ordered his men to execute Pym, but changed his mind and decided to kill him himself. Before Cross could kill his former mentor, Scott Lang broke free from the glass enclosure and he and Hope van Dyne began fighting Cross' guards. Pym fought Darren Cross and was shot in the shoulder before Cross escaped. Lang and Van Dyne ran to Pym's aid and he ordered Lang to stop Cross while van Dyne stayed with him. Van Dyne told them they had to escape as the entire facility had been rigged to explode. Pym revealed that the tank key-ring he kept with him was in fact a real tank which had been shrunk down. They transformed the tank to its original size and used it to escape. Van Dyne and Luis took Pym to get medical attention from a nearby ambulance as they witnessed the Pym Technologies building exploding from the C4 which Scott Lang had planted inside. As Pym was treated for his injuries, Lang tracked down and fought Cross. Eventually, Lang was able to kill Cross by damaging his suit's internal mainframe, briefly teleporting him to the Quantum Realm before he was able to return to normal size.

Learning of the Quantum Realm
"There must be something else. Well I suppose the human mind just can’t comprehend the experience, but you made it. You went in and you got out, that’s amazing."

- Hank Pym to Scott Lang

Back in his mansion, Pym spoke to Scott Lang about what he remembered from his experiences within the Quantum Realm and how he escaped, pushing him for any new details although Lang assured him that he had no recollection of what happened to him, which Pym explained must mean that the human mind cannot cope with such an experience which was why Lang had failed to remember. Although he gained no real evidence about the realm, knowing that it was possible for someone to go to the Realm and return sparked a new passion within Hank Pym and a hope that it could be possible for Janet van Dyne to return to the normal realm once again. As Lang left, he was walked out by Hope van Dyne; when Pym went out into the corridor, he found Lang and van Dyne kissing. Lang claimed that it was van Dyne who had kissed him but Pym told him that he was full of shit; Lang did not disagree.

Wasp Suit
"I realized you can't destroy power. All you can do is make sure it's in the right hands."

- Hank Pym to Hope van Dyne

Hank Pym later took Hope van Dyne into the basement of his mansion, explaining to her that before her death in the 1980's, he and Janet van Dyne had been working on a prototype for a new Wasp Suit. He told her that although they had made it for her mother, he now knew that it should be used by Hope van Dyne. As Pym proudly unveiled the suit to his daughter, she did not disagree and happily accepted the suit, noting that it was about time this happened.

New Upgrades
Pym and Scott Lang worked together on making the Ant-Man Suit grow instead of shrink. They were successful in one of the laboratory trials, but only for a few seconds before Lang passed out.

Becoming a Fugitive
In 2016, Lang (while using the Ant-Man Suit) violated the recently signed Sokovia Accords after secretly running off to Germany to assist Captain America and his team, who were fugitives under these accords for unauthorized superhero acts.

Lang brokered a deal with Thaddeus Ross to serve two years of house arrest. However, under the accords, Pym and Hope van Dyne, now considered fugitives for developing Scott's tech, were forced to go on the run. Outraged over what Lang had done, Pym and van Dyne both severed ties with him. Sometime during Lang's sentence, they began using a secret, portable lab that could be shrunk at will to continue their work.

First Encounter with Ghost
"Wing and blasters." "So I take it you didn't have that tech available for me." "No, I did."

- Scott Lang and Hank Pym

in 2018, the year Scott Lang was due to finish serving his sentence, Pym began building a tunnel designed to be able to provide direct transport into the Quantum Realm. Since Scott was able to successfully come back from the Quantum Realm, he figured that that his long-lost wife: Janet, could possibly still be alive in it.

One day - after Pym activated this tunnel - Scott Lang, with whom he had no contact for two years, called Pym only a few minutes later, reporting to have had a dream about the Quantum Realm in which he saw Janet playing with a young Hope. Immediately after receiving this message, Pym arranged for Hope van Dyne to retrieve Lang. After successfully bypassing Lang's tracking device, van Dyne delivered Lang to the lab. Despite still upset at Lang, Pym filled him up on the details about the tunnel, telling him that he might have had a quantum entanglement with Janet down in the Quantum Realm. Hank and Hope took Scott along for a deal with Sonny Burch for the final part they needed, but the deal went sideways when Burch deduced Hope's identity and Hank's by proxy. Hope took action as the Wasp, forcibly taking the part they had paid for and leaving. But before she could return to Hank and Scott, she was attacked by a unstable masked figure who attempted to steal the part. Scott donned a new Ant-Man suit which Hank claimed was a "work in progress" and joined the fight, saving Hope but allowing the "ghost" to get away with the shrunken-down lab.

Meeting Bill Foster
After finding that Ghost had turned off the tracker on the lab, the trio was left with no other option than to find Hank's former partner Bill Foster and request his help. Bill had worked with Hank on a project called Goliath where he had managed to grow up to 21 feet tall, but like with the quantum tunnel, Hank had seen the malicious uses for this technology and had cut off the project, discrediting Bill and destroying evidence that the project had ever existed in an effort to make sure it was never recreated. Despite Bill's lingering bitterness about these events, he agreed to help them, advising that they use a regulator from one of Hank's old suits to track the lab. Hank soon despaired at this, however, realizing that there were only two suits whose regulators he could use: the first Ant-Man suit, whose regulator had been destroyed when Scott went subatomic; and the second suit Scott stole to help Captain America, which he had promised to Hank that he had destroyed. Scott revealed that he did not, in fact, destroy the suit, though, having instead shrunk it down and mailed to Luis before he turned himself in, much to Hank's indignation. He then realized that the trophy in which he kept it, one that his daughter had given him, was in her possession at her school's show-and-tell. Scott and Hope snuck into the school and retrieved the suit before using the regulator to track the lab to Ghost's lair, where they found a young woman sleeping in a bizarre chamber. As they tried to steal back the lab, she woke up and knocked the trio out. When Hank came to, he found that he, Hope, and Scott had been bound to chairs. The young woman revealed herself to be Ava Starr, daughter of another of Hank's former partners, Elihas Starr. Ava explained that her father, after being fired and discredited from Hank's quantum tunnel project, was desperate to prove that he had been a part of the experiment and tried to recreate the tunnel in Argentina with disastrous consequences: everyone in the facility was killed by an explosion from the malfunctioning tunnel, including Ava's mother and father. Ava, however, was left intangibly unstable. She explained that this meant that she could pass through walls and turn invisible, and even exist in multiple realities at once, but it hurt her immensely and she had trouble controlling it. Additionally, it would soon kill her if not cured.

Bill then revealed that he was working with Ava to find said cure and had been since she was a little girl. They both had settled on the realization that a great quantity of quantum energy was the only thing that could even temporarily cure her, and that such a sum of energy could only come from Janet herself, who had been absorbing quantum energy for several decades. Believing that taking this energy from Janet would kill her, Hank refused to help and faked a heart attack as a means of distracting Bill and Ava long enough that the trio could escape with the lab.

Arrested
The three set the lab up in the Redwood Forest and continued their work, using the newly acquired part to complete the mechanism and open a stable tunnel. This allowed Janet to temporarily possess Scott's body, sharing a tender moment with Hank and Hope as she gave them her exact coordinates but warned them that they had a matter of hours before the instability of the quantum realm would make it impossible to find her again for centuries. The trio was given notice that a resentful Burch had tipped off an inside man in the FBI as to Scott's breaking of house arrest and Hank and Hope's location. Scott fled to get back home before the FBI could find that he was missing, leaving Hank and Hope to try and escape, but unsuccessfully, by the time their lab was shrunken, a large team of SWAT and FBI agents had surrounded them and forced them to surrender. The two were taken into custody at the FBI agency while Ghost stole the lab after killing Stoltz, who was secretly trying to take the lab to Burch. While in custody, however, Scott managed to sneak in Hope's suit and a disguise for Hank which allowed them to escape.

Rescue of Janet van Dyne
"You never said it was so beautiful, Scott."

- Hank Pym

The trio tracked the lab to San Francisco Bay where Sonny Burch boarded a ferry. Ant-Man's regulator malfunctioned, causing him to grow 65 feet tall. He swam across the bay and easily retrieved the lab, but was barely able to get it to safety on land before passing out from the effort of staying in his giant form. Realizing he would run out of oxygen soon, Waspswam down after him and fixed his regulator, saving his life. Meanwhile, Pym readied the quantum tunnel and donned a Quantum Realm Exploration Suit. He shrank down into the quantum realm, having a brief run-in with dust mites before continuing through the quantum void and into the quantum realm. As he began his journey, the exposure to Pym Particles caused him to begin losing his mind, which was the reason he had given up being Ant-Man originally. As he was about to sink into insanity, a figure emerged and imbued him with quantum energy, saving him. The figure then revealed herself as Janet van Dyne. The two began their journey back to the surface, during which Ghost began to siphon Janet's quantum energy, causing her extreme discomfort. This was halted by the arrival of Ant-Man and Wasp, who fought her off until Pym and Janet returned. Sensing Ghost's brokenness and life-threatening condition, Janet willingly imbued Ghost with quantum energy to temporarily heal her.

Pym and Janet soon retired happily to the coast together, choosing to keep a low profile since Pym was a wanted fugitive and Janet had been "dead" for 31 years.

Thanos' Victory
"These are Pym Particles, all right? And ever since Hank Pym got snapped out of existence, this is it, this is what we have."

- Ant-Man to Hulk

Pym and Janet van Dyne then continued to help with the harvesting of quantum energy from the Quantum Realm to help cure Ghost, creating a new Quantum Tunnel within Luis' Van. Pym, Janet, and Hope van Dyne were monitoring as Scott Lang was sent into the Quantum Realm. Just as they were getting prepared to bring him back out, however, the three were turned to dust along with one half of the universe's life due to Thanos' Snap.

However, five years later, Lang managed to escape the Quantum Realm after a rat activated the Quantum Tunnel. Despite five years have gone by, Scott was only trapped in the quantum realm for five hours. With this knowledge, Lang traveled to the New Avengers Facility, shared his experience with Steve Rogers and Natasha Romanoff, and came up the idea to use the Quantum Realm to travel back in time, collect the Infinity Stones, and undo the Snap. But, because Pym was one of the victims of the Snap, the Avengers only had enough Pym Particles for one round trip each to their destinations.

Theft of the Space Stone
"Dr. Pym?" "That would be the number that you called, yes." "This is Captain Stevens from shipping. We have a package for you." "Bring it up." "Well, that's the thing, sir. We can't." "I'm confused. I thought that was your job."

- Steve Rogers and Hank Pym

During the Time Heist, Tony Stark and Scott Lang failed to retrieve the Tesseract during the Battle of New York after the 2012 version of Loki acquired possession of it and used it to escape. When the duo regrouped with Steve Rogers, Lang claimed that they had failed since they only had enough Pym Particles for the trip back to 2023. Stark then remembered that in 1970s, the Tesseract was housed in Camp Lehigh where Pym also worked, meaning that they could reacquired the Space Stone and more Particles. While Lang returned back to the New Avengers Facility in 2023, Stark and Rogers traveled back in time to April 7, 1970.

Rogers then disguised himself as "Captain Stevens" and called Pym at his laboratory, notifying him that the package he was supposed to receive was accidentally opened by the shipping station. Horrified by this news, Pym ran out of his laboratory, allowing Rogers to get inside and steal a few Pym Particles.

Resurrection
As the Avengers succeeded in reviving Pym and every living being in the universe, Hope van Dyne was summoned to join the battle against Thanos and his army at a recently destroyed New Avengers Facility. Eventually, Tony Stark sacrificed his life using the power of the Infinity Stones to wipe out time-displaced Thanos and his army into non-existence. Pym, together with his wife and daughter, attended Stark's funeral the following day, despite having differences between him and the Stark family.

Personality
"Hank was a terrible partner. Temperamental... stubborn, impatient. Sooner or later, he just pushed everyone away."

- Bill Foster

Hank Pym is a multi-faceted man, a passionate scientist who did not wish to see his work fall into the wrong hands. Pym was also a caring father and husband; however, once his wife, Janet van Dyne, sacrificed herself to save the world from a soviet ICBM, Pym became colder and distant. He sent his daughter Hope off to boarding school in order to protect himself and his young daughter from their loss.

Pym has an aggressive side and a tendency to lash out when provoked. When he was insulted by S.H.I.E.L.D. Head of Defense Mitchell Carson about not being able to protect his wife, Pym smashed Carson's face into the desk to the point where his nose bled and threatened him should he mention his wife ever again. This also happened with Darren Cross when Pym found out about Cross wanting to sell Pym Particles to a terrorist organization. He was willing to destroy Pym Technologies to keep his technology out of the wrong hands, though he showed concern for the people inside and planned for it to be evacuated, despite leaving at least some of Cross' men and knocked out terrorists inside when the building was destroyed. Luis also noted that due to Hanks abrasive and temperamental nature he had frequent fallings out with his friends and colleagues.

Pym is extremely overprotective of his Pym Particles and distrusts anyone who shows interest in them, due to being concerned that the Pym particles would change the nature of warfare and thus the world. During his time at S.H.I.E.L.D. he refused to let anyone use the Ant-Man suit and Pym particles except for himself. He immediately quit S.H.I.E.L.D when he found out they attempted to copy the Pym Particle. When he found out Cross was close to replicating his formula, he immediately plotted to steal Cross' Yellowjacket suit and destroy his own former company to prevent Pym Particles from being sold. Pym even fired Bill Foster for attempting to steal his work and also Elihas Starr for the same reason during his time at S.H.I.E.L.D. According to Foster, Pym had much of an ego during his career. Pym also has a habit of pushing everyone away because he's so cynical. He even cut ties with Lang when he accidentally made them fugitives for helping Captain America.

This distrust seems to be even higher towards the Stark family, as Howard Stark had been experimenting with Pym Particles. When Scott Lang asked to bring in the Avengers to help with Cross; Pym replied that he had spent much of his early life keeping Pym Particles out of the hands of Howard Stark and he would not let it fall into the hands of Stark's son Tony. Pym also believes in second chances and redemption, such as Scott Lang, for example. It would appear that after Tony Stark sacrificed himself to defeat Thanos for good and having helped in his and his family's revival, Hank had came to abandon his grudge towards the Stark Family, as he attended Tony's funeral and looked somber.

It should be noted that even before he had hope that Janet could still be alive, Hank never attempted to move on and love again. This shows a positive quality of Hank; he was true and faithful to the woman he loved.

Powers

 * Insect Manipulation: Pym can communicate with ants, allowing him a rudimentary form of control over the insects. He uses electromagnetic waves to stimulate their olfactory nerve center and to mimic the pheromones of insect sized organisms using the EMP Communication Device. He could effectively project his will into ants and other insects, which influence their actions and behavior. As of now, he uses the device in the form earpieces similar to hearing aids or coiled communication earpieces. Scott Lang and Hope van Dyne also have these earpieces.

Former Powers
"He just kicked your ass full-size, you really wanna find out what it's like when you can't see him coming?"

- Howard Stark to Mitchell Carson

Ant-Man Suit
 * Size Manipulation: Using his developed technology, Pym was able to reduce himself to approximately the size of an ant. He still maintained his regular sized strength and durability while in a reduced scale as the process amplifies the amount of force he can generate and increases his density. Additionally, the process of altering size compresses force and energy, manifesting as brief shockwaves of vibration around the target, which briefly augments his force and momentum as he returns to normal size.
 * Superhuman Strength: The process of size alteration grants him superhuman strength, which allowed him to defeat opponents of normal human size, as well as leap vast distances and great heights.
 * Superhuman Durability: The process of size alteration grants him superhuman durability, enough to survive falls from great heights and other impacts that would injure or kill even normal sized humans.

Abilities

 * Genius-Level Intellect: Hank Pym is one of the smartest humans in the world, a scientist who focused on the development of a technology that other scientists were unable to replicate, such as discovering size-shifting Pym Particles.
 * Master Scientist: One of most brilliant scientific geniuses in history, Pym has tremendous knowledge and unmatched understanding in several fields of science, particularly entomology and atomic physics, but also chemistry. Indeed, he was considered the world's foremost entomology and nanotechnology expert and, was once recruited by Howard Stark and Peggy Carter as a consultant for S.H.I.E.L.D., in addition to him later also advancing the fields of nanotechnology, human enhancements, as well as molecular and atomic studies with his company Pym Technologies. Hence, Pym was able to discover and isolate the extremely rare inter-dimensional Pym Particles, as well as personally go on to harness them. Indeed, S.H.I.E.L.D. were unsuccessful in their covert attempt to replicate Pym's work, and even Pym's protege Darren Cross, a genius himself, took several years of trial and error to replicate it, and even then failed to realize the negative effects of using the formula without specialized protection.
 * Master Engineer: Pym is a brilliant engineer, especially in a field of nanotechnology, having personally created the Pym Particle-harnessing Ant-Man Suit, as well as the EMP Communication Device. Pym later worked with Scott Lang to render the suit capable of also increasing in size, and they were ultimately successful.
 * Expert Businessman: Pym is a highly trained businessman, having founded his own research company, Pym Technologies, which earned him a distinguished reputation in the technology community.
 * Skilled Combatant: While rarely shown, Hank is a capable fighter even at his old age. In one swift move, he broke Mitchell Carson's nose with his own desk and in a surprise attack punched Darren Cross in the face, surprising the latter with his strength. Having trained in the US Army, it is possible that he is skilled in certain fields of combat tactics.

Equipment
"This is not some cute technology like the Iron Man suit. This could change the texture of reality."

- Hank Pym to Scott Lang


 * Ant-Man Suit: Created by Hank Pym, the Ant-Man Suit is a suit that maximizes the use of the Pym Particles while also protecting the wearer from the negative side-effects of using Pym Particles.
 * Pym Particles: Pym Particles are subatomic particles that are capable of shunting or adding mass and reducing or increasing scale of any form of matter, compressing physical forces around such objects or organisms that they are applied to, as well as increasing density and strength of the subject. Pym created and harnessed the Pym Particles in an intelligence organization called S.H.I.E.L.D..
 * EMP Communication Device: Pym created a communication device through many rigorous tests to ensure its functionality. It appeared to work perfectly with all ants except for bullet ants, who seemed to ignore all the orders he had given to them. He eventually used it for his Ant-Man Suit to shrink down and talk to the ants on their level. They still continued to be defiant and chased him around until they ran into a centipede that attacked them. Pym and the bullet ants even worked together to defeat the centipede.
 * Pym Particles Disks: Pym created a complementary weapons technology for Scott Lang. When thrown, the discs release their Pym Particles upon impact with the target, triggering one of two effects depending on the type of disc used. The red disk shrinks an object or being. The blue disk enlarges any target, Pym uses these disks on a small tank.
 * Quantum Tunnel: Whilst on the run from the government, Pym and his daughter Hope van Dyne created a device that could safely transport matter in and out of the Quantum Realm. Pym himself uses this technology to transport the Quantum Vehicle, to save his wife Janet.
 * Quantum Vehicle: Used in conjunction with the Quantum Tunnel, the Quantum Vehicle allows the user to traverse the Quantum Realm with ease. Pym uses this technology to travel to Janet's location. The Quantum Vehicle uses tri-engines and is equipped with a location device and also infused with Pym Particles. It moves and controls much like an airplane, using a control stick.
 * Quantum Realm Exploration Suit: This suit allows Pym to safely traverse the Quantum Realm outside of the Quantum Vehicle. It mirrors his Ant-Man Suit design, however, lacks any self-shrinking capability. Pym uses it to save his wife however removes the helmet, exposing himself to Quantum Energy, showing how vital the suit is when visiting the Quantum Realm.
