"He's a butcher." "And what are you?" "I'm a man trying to put my family back together!"

- Calvin Zabo and Raina

Calvin "Cal" Zabo, born Calvin L. Johnson, is a medical doctor of ambiguous morality. After being violently separated from his gifted wife and baby daughter by HYDRA and S.H.I.E.L.D., he started the quest to avenge his wife and find his daughter, committing numerous crimes that have caused others to consider him a Monster. During this time, Zabo developed a formula that gave him enhanced strength. However, the side effects of the unstable formula gave Zabo an erratic personality and severe issues controlling his emotions, particularly anger.

After discovering his daughter's whereabouts, he made a temporary alliance with Daniel Whitehall's HYDRA branch so he could take his daughter to the ancient Kree City where she could fulfill her destiny. However, after the Terrigenesis, his daughter stayed with S.H.I.E.L.D., and Zabo formed a team of enhanced criminals to use them against S.H.I.E.L.D. This attracted the attention of the Inhumans who kidnapped him and brought him to Afterlife where he was reunited with his wife. One more encounter with S.H.I.E.L.D. and HYDRA led to Zabo and his wife developing a plan to destroy S.H.I.E.L.D. once and for all, until Phil Coulson convinced him to fight his wife to protect his daughter, resulting in Zabo killing his wife to save his daughter. In the aftermath of the battle, Zabo's mind was wiped by the remaining resources of Project T.A.H.I.T.I. and he lived the rest of his life as a happy veterinarian named Dr. Winslow.

Doctors Without Borders
Calvin Johnson had a medical practice in Milwaukee, Wisconsin, when he decided to work with "Doctors Without Borders" and moved to China to work there temporarily.

Hunan Province
"I worked in a clinic. People liked me. I liked myself."

- Calvin Zabo

Calvin Johnson worked in a clinic in China as a young adult, where he met Jiaying, who would become his wife. As he could not understand Chinese, she helped him with translations. After a while, the two of them had a daughter, whom Johnson delivered himself, and they named her Daisy.

Men claiming to be S.H.I.E.L.D. agents, but who were in truth members of HYDRA, came to their clinic and demanded that Jiaying be handed over. Johnson and Jiaying resisted, but their efforts were in vain, as she was kidnapped nonetheless. He then left Daisy among people he trusted, and set off to search for his beloved wife. He later found her remains in Austria, apparently dead as a result of a vivisection performed by Daniel Whitehall. When Johnson discovered her body, he refused to allow his beloved wife to die and using his medical skills, put her body back together until her Inhuman powers allowed her to recover and return to life.

Understanding, however, that he would be unable to defeat Whitehall in his current form, Johnson began to try and make himself stronger by dabbling in chemistry. Eventually he concocted a formula which made him stronger, but also much more volatile. He and Jiaying later returned to their village, only to find that Daisy had been rescued by S.H.I.E.L.D.. Jiaying ordered her husband to kill everyone, and so he did, butchering the entire population of the village and the S.H.I.E.L.D. teams who were coming to extract an 0-8-4. The first S.H.I.E.L.D. team were killed and a second team, composed with Linda Avery and Richard Lumley, were succeed to extract Daisy to safety. But when they land, each members of the team, including Linda Avery, were killed by Johnson himself. Lumley manages to give Daisy safety and arranges to disappear from S.H.I.E.L.D. circulation. Johnson then set off to find his daughter. In his attempts to do so, Johnson came across another gifted individual, Wendell Levi. With Levi, Johnson was able to look at S.H.I.E.L.D.'s Index, but could not find Daisy on it.

When Johnson told Jiaying that he had lost their daughter, she was heartbroken and divorced him. Johnson swore that he would reunite their family one day. He later changed his last name to Zabo.

Monster
"I wasn't strong. I couldn't protect the people I loved. So I tried to change, improve myself, with chemistry. Results were... inconsistent. Some volatility issues. But I keep working on a formula. Always tweaking.."

- Calvin Zabo

Zabo found Raina living on the streets as a beggar, holding onto stories that her grandmother had told her. At that time, she was in Thailand with a group of friends who called themselves "freaks." He sheltered them and raised their self-esteem. Meanwhile, he revealed to Raina that, if she could reunite him with his daughter, he could prove that her grandmother's stories about the Kree were true.

Years later, Zabo was visited by Raina, who had discovered his daughter, a S.H.I.E.L.D. agent now going by the name Skye, and presented him with a picture.

The Diviner
"Bring me my daughter and I will show the both of you."

- Calvin Zabo

Raina retrieved what he truly wanted, the Obelisk, and in order to test its authenticity, instructed Raina to hold it. Instead of turning into stone, the Obelisk glowed orange with the Words of Creation, confirming Raina was an Inhuman. He was pleased by the Obelisk's reaction. Raina begged Zabo for more information about the Obelisk, but in order to explain to her its significance, he required his daughter. He ordered Raina to bring him his daughter, and he would show the both of them. A few days later Zabo was performing an illegal surgery on two gang members who had been injured in a fight; one of the gang members drew a gun, saying he planned on killing the man who injured his friend. Zabo politely asked the gang-member to put the gun away, which the man did since Zabo asked politely. Raina appeared, having been threatened by HYDRA leader Daniel Whitehall and begged him to give up the Obelisk. He refused, saying that she has still not brought him Skye. Grabbing Raina's throat, he asked her if she feared Whitehall more than him. Raina told him he was losing control and needed her to help him with his rage. Loosening his grip, he refused to give up the Obelisk and told her to plead to Whitehall for her life. As Zabo returned to the surgery, the gang-member told him to calm down, Zabo did not react well and murdered both of the gang-members. Later, Coulson's team of S.H.I.E.L.D. agents reached his hideout, after following Raina, only to discover it deserted. A picture of him was left on the ground and Skye found it, leaving her in a state of shock having finally seen an image of her father's face. Meanwhile Zabo was hiding in his car outside and watched the team searching his hideout through a secret camera embedded in a clock on the wall. After seeing the two corpses of the two gang-members he had killed, Skye called him a monster. In response he angrily smashed his tablet, which he used to access the hidden cameras. He threw the broken tablet out of the window and drove away.

The New Alliance
"We share a common enemy, guy named Phil Coulson, I thought maybe together you and I could kill him, along with, you know, everyone else."

- Calvin Zabo to Daniel Whitehall

He then went to HYDRA Laboratories to meet Daniel Whitehall, as he arrived he commented on the fact that they seemed to be moving locations. When the guards tried to stop him, he promptly slayed them both before apologising for making a mess on Whitehall's table with their blood. He then showed Dr. Whitehall the Obelisk, and offered not only to teach him how to control the power of the Diviner, as it is called in its native language, but how to survive it. When asked his motivation, Zabo said that they had a common enemy: Phil Coulson and together they could kill him and everybody else.

With his knowledge of the Diviner, Zabo was able to help Daniel Whitehall and Toshiro Mori to design a new deadly weapon know as the Splinter Bomb, which HYDRA used to assassinate world leaders from the UN.

Working with Daniel Whitehall
"I've lost everything important to me. And I want to kill those who took it and finally be reunited with my family." "Reunited?" "In the Afterlife."

- Calvin Zabo and Daniel Whitehall

Daniel Whitehall had a meeting with his scientists, but was disgusted when they only told him information about the Diviner that he had already known since 1945. Zabo was brought in and immediately insulted Whitehall's previous efforts with the Diviner, when he tried to take a step forward Whitehall's guards aimed their guns at him. Whitehall explained that he currently knew that only a select few could touch the Diviner without it killing them, when he called it a weapon Zabo informed him that it was a key and only killed those it did not deem worthy of unlocking it's true power. He told him that if the Diviner was taken to a special place it would do something he claimed would be much cooler than killing. As Zabo and Daniel Whitehall continued their discussions on the Diviner's power, Whitehall told him that he believed that the Kree had come to conquer the world with the Diviner, but Zabo explained they had come to end all life on Earth apart from those the Diviner deemed worthy. Zabo promised Whitehall that he would be able to take a team into the Kree City to use the Diviner to it's potential. When Whitehall accused Zabo of planning to steal the Diviner's power for himself, Zabo assured him that he was not worthy. Whitehall questioned why Zabo was willing to help him in his quest, Zabo explained that it was because he had nothing to lose and he wished to kill those who took him life away from him.

Meeting Phil Coulson
"You realize we're talking life and death here." "I know. It's exciting, isn't it? I mean, both sides racing to the temple, life and death, flesh and blood, emotions! Who knows how it'll shake out? All I know is, my baby's gonna be right there in the center of it."

- Phil Coulson and Calvin Zabo

Zabo was given a team of operatives to take to Australia to find the city matching the City Blueprints. When S.H.I.E.L.D. arrived on the scene, also looking for the city, Zabo disguised himself as a hostage. When agent Antoine Triplett was shot during a firefight there, Zabo assisted in saving his life, in order to talk face-to-face with Phil Coulson. When he accidentally revealed his identity to Coulson, he cut Triplett's brachial artery and told Coulson he would only save him if he was allowed to escape. Zabo explained that the Diviner had something within it, but when Coulson asked if it was equal to the Tesseract, he had no clue of the comparison. Zabo then escaped, leaving the medical care of Triplett to Coulson and Fitz.

New Member
"It's always good to look your enemy right in the eye."

- Calvin Zabo

Upon Zabo's return to HYDRA, Daniel Whitehall introduced him to Grant Ward, who had been a member of Coulson's Team and worked closely with Skye, before betraying them to rejoin HYDRA. Whitehall explained Ward had just been allowed to rejoin HYDRA after murdering his brother Senator Christian Ward. Whitehall believed that as a team they would be able to be able do achieve many great things for HYDRA. Ward asked him how his meeting with Coulson had gone as Coulson could be a difficult man to deal with, Zabo said that it was worth while, as it was always worth looking your enemy right in the eye. As he said this he looked at Whitehall.

Family Reunion
"Now that he's served his purpose, I'm gonna kill the man that destroyed my life. Best day ever."

- Calvin Zabo

Zabo sat in a room and waited for Grant Ward to bring Skye to him inside the Ponce de León Theater‏‎, a temporary base HYDRA established in San Juan. Zabo told Skye how he had waited so long to be reunited with her. Though she was repulsed by him, calling him a monster, she listened as he told her of how he met Jiaying. She corrected his story when he said that S.H.I.E.L.D. took her to Austria to kill her, revealing that it was HYDRA that truly did the deed. Zabo told her he had known all along that Whitehall killed his wife and that he was using the HYDRA leader to reunite them; and once they were together, he planned to rip Whitehall apart in revenge. Whitehall had a meeting with Zabo, Skye, Ward, and Raina, where he expressed his gratitude to Zabo for helping him locate the city and giving him understanding of the Diviner. He then explained that he wished to know if Skye would survive touching the Diviner, Zabo nodded at her to assure her it was safe, while he prepared a scalpel in his hand. When Skye picked up the Diviner, she attacked a HYDRA operative with it as Zabo killed his guard, leading to a stand-off. Whitehall explained that he had remembered who Zabo was and told him that he would not get his revenge for Whitehall killing his wife, Zabo was then knocked out by one of the guards. When he awoke he attempted to kill Whitehall again but was stopped with a Control Device that paralyzed him remotely. As he lay on the ground, unable to move, Whitehall mocked Zabo, telling him he wanted him to watch as he tortured Skye to death.

Denied Revenge
"WHAT DID YOU DO?!" "You're welcome..." "You killed him! He was mine and you killed him!"

- Calvin Zabo and Phil Coulson

Once Whitehall had left the room to investigate the gunfire that was heard, Zabo used the opportunity that Ward gave him by distracting their guard to remove the Control Device on his neck and kill the guard. He did not free Ward or Skye because he did not want her to see or Ward to help him kill Whitehall; he left them still bound. Zabo found Daniel Whitehall standing alone and prepared to finally exact his revenge on the man who robbed him of his life. Whitehall spotted him and raised his gun, preparing to shoot to shoot Zabo, but Phil Coulson shot the HYDRA leader from behind, Zabo could only watch in shock and horror as his enemy died in front of his eyes before he could get his long planned revenge. Angered that he could not exact his revenge upon his greatest enemy, Zabo took his rage out on Coulson. Coulson fought back for a while, but Zabo chased him down and eventually got the upper hand and beat Coulson into submission. Skye found the two struggling, Coulson having nearly been beaten to death and at gunpoint, told her father to leave and never see her again. Zabo agreed to leave, but promised that she would eventually come to him for comfort, because no one other than him would understand her struggle after her transformation. He then revealed her birth name to her: Daisy, before turning around and walking away devastated.

In Hiding
"We can't stop now. We can't let them make us afraid or make the world afraid of us! They are the criminals, and we're gonna shine a light on that!"

- Calvin Zabo

Zabo went into hiding following his confrontation with S.H.I.E.L.D. and HYDRA, intending to leave Puerto Rico inside one of the container units of a cargo ship. Raina, who had traveled with Zabo using that method many times before, went to the cargo ship to confront him, having been transformed into a new Inhuman form, which she considered monstrous. She demanded to know what had happened to her, but Zabo simply told her that she had become what she always wanted and there was no way back. Raina then revealed that Skye had also gone through a transformation; he danced with glee and swore he would have to help her through her confusion the same way Jiaying helped others years before. However, his glee turned to horror as he reminded himself that Skye would go running back to Coulson's arms, who would most likely put her on S.H.I.E.L.D.'s Index. He convinced himself that Skye would come to him when his prediction regarding her friends growing to fear her came true. A dejected Raina retorted that it would never happen nor would Skye ever love him, though he ignored her. He then got the idea to contact other powered people he knew from S.H.I.E.L.D.'s Index so he could exact his revenge on Coulson. When Raina told him that she could not live looking like that, Zabo dismissed her and left.

Slicing Talons
"Ladies and gentlemen, I want to welcome you to this historic matchup between the S.H.I.E.L.D. Eagles and us, rivals and underdogs, the... Slicing... Talons?"

- Calvin Zabo

Zabo quickly reconnected with Wendell Levi to assemble a group of people from S.H.I.E.L.D.'s Index to help him destroy Phil Coulson. He removed the microchip in Levi's arm that kept him from accessing technology and Levi hacked into the files of the Index to find potential members that Zabo felt was wronged by the organization because they had powers. Zabo recruited Francis Noche; then the three went to the home of Karla Faye Gideon and convinced her to join by freeing her of her restraints. Together, they worked out a plan to break into the Brynmore Psychiatric Facility and recruit the enhanced individuals there who they had located from the Index. While Zabo distracted the guard, Karla Faye Gideon killed him and Wendell Levi disabled the security systems. Before the power was shut off, Zabo took the opportunity to smile and wave at the security camera as a mocking message to Phil Coulson. Once Francis Noche had given them access by ripping open the gates, Zabo and his team freed the Facility's prisoners John Bruno and David Angar. Leaving Bruno behind to kill the S.H.I.E.L.D. agents when they came to investigate, the group travelled to Manitowoc, Wisconsin to exact their revenge. Along the way, the team stopped at a diner to eat where Zabo commented on Wendell Levi not eating at all as he claimed to not enjoy food. Zabo was able to gain the sympathy of his compatriots by explaining to them how S.H.I.E.L.D. had stolen his daughter from him after his wife had been murdered, and how Coulson had killed Daniel Whitehall, despite his desire to do so himself. He explained to the group how he gained his strength after experimenting with body enhancing chemicals. The group desired to teach Coulson and S.H.I.E.L.D. a lesson and show the world the crimes they had committed to them.

Confronting Coulson
"Let’s welcome Phil Coulson to the field. Here is a fun fact: He killed the man I had been plotting to kill for two and a half decades! Disappointment!"

- Calvin Zabo

At a high school in Manitowoc, David Angar's muzzle was removed by Levi and Gideon, but before he could scream, Zabo advised him to "make it count"; Zabo watched smiling as Angar screamed in the middle of a football field filled with athletes and cheerleaders causing them all to lose consciousness. They then awaited Phil Coulson's arrival. When Coulson arrived, Zabo spoke on a microphone, announcing the team as the Slicing Talons and that they wanted revenge on S.H.I.E.L.D. for the wrongs that it has done to gifted individuals. He reminded Coulson that he wanted his own revenge for Coulson taking away his chance of finally killing Daniel Whitehall after twenty five years of planning. Zabo approached Coulson with his teammates, except for Gideon who was in the bleachers with a group of unconscious students, when Melinda May arrived with Skye at gunpoint. This made Zabo hesitant and explain his motives over the microphone. He then passed the microphone to Angar, intending for him to kill the S.H.I.E.L.D. agents once Skye was safe. Before Zabo could kill Coulson, Gordon suddenly teleported onto the football field and warped Zabo away, taking him back to Afterlife.

Reunion with the Inhumans
"You're making too much noise." "Noise? I'm sounding a battle cry! I'm protecting us from S.H.I.E.L.D.!" "There is no "us." You're not one of us. You're just a science experiment."

- Gordon and Calvin Zabo

Zabo threw a tantrum and destroyed the furniture in the room he was placed. Gordon later entered and asked if Zabo was finished. Zabo asked Gordon why he teleported him instead of Skye; Gordon explained that Zabo was creating too much attention towards the Inhumans and, since he was not one of them, it was not appreciated. Gordon then motioned Zabo to the door to see the one who would decide his fate. Zabo adjusted his attire to be more presentable and walked slowly out the door.

Keeping His Promise
Ultimately, Zabo found himself in a room with no exit, neither windows or doors; he pounded and rampaged to no avail. One day, Gordon teleported within the room; Zabo demanded to be released. Zabo soon realized that, after days without a visitor, Gordon was there because Skye was in Afterlife. Zabo then attacked him, but Gordon used his strength and teleportation to strike and evade Cal, who eventually relented because he had hurt his already sore hands, Gordon told him he may never leave Afterlife because of his actions. Hours later, while Zabo still suffered from the pain in his hands, Jiaying and Gordon appeared in the room. She thanked and hugged him for keeping his promise to reunite her with their daughter Skye and help her fulfill her destiny in becoming an Inhuman. However, when he asked her if he could see her, Jiaying told him he could not, knowing that it was due to his uncontrollable anger, Zabo reluctantly agreed, although he wished to stay in Afterlife on the off chance Jiaying or Daisy might change their minds.

Family Dinner
"I'd wanted so badly to make everything perfect for tonight and suddenly it is."

- Calvin Zabo and Daisy and Jiaying

Zabo was informed by Jiaying that he would have an opportunity to have dinner with her and Skye. Zabo prepared for the meal by collecting daisies and wearing a suit. When Skye and Jiaying arrived, he handed Skye the flowers and greeted her warmly. Jiaying mentioned that Skye did not know when her birthday was, and Zabo immediately told her that it was July 2nd, going on to happily tell the story of her birth. Zabo then revealed that Skye was born in 1988, not 1989 as Skye had originally believed.

Leaving Afterlife
"What an idiot I've been huh, I see what's happening. You were going to dump me here like yesterday's trash. You don't want to spend time with me, this isn't Daddy's day out. This is goodbye."

- Calvin Zabo to Skye and Lincoln Campbell

Zabo was told that he could leave Afterlife to pick up his belongings, but Zabo was uninformed that Gordon would simply leave him behind so he could never return to Afterlife and never see his family again. While sitting in his room, Skye knocked on his door and asked if she could come in before asking him where he was going. Zabo happily told her he was going to retrieve his belongings, but when Skye asked if he was going to China, Zabo told her he had a practice in Milwaukee, and that was where he was going. When Skye asked if she could go with him, Zabo happily agreed. Gordon dropped off Zabo and Skye in Milwaukee. Zabo tried to show his daughter all the old places he knew, but they had all closed down in the years since he had been there. Zabo remained nervous, often asking if Skye was bored spending time with him, but she assured him that he was a lot of things but boring was not one of them. At one point Skye bumped into a stranger, Zabo began to lose his temper, demanding the stranger apologize to Skye, but she managed to calm him down. Eventually, he took her to his old office, where all his things were left untouched, revealing to her that he in fact owned the entire building. Skye noted that Zabo's original surname was Johnson, but told her that he had changed it when he went on the run. He showed Skye his grandfather's operating kit he had used to sew Jiaying back together. His enthusiasm was spoiled when Skye told him that he was holding on to the idea of raising a family, a thought that would never come true and she told him it was time to move on. Skye let it slip that Zabo was not to return to Afterlife. The two were interrupted by a noise in the building. When they went to investigate, they found it was Lincoln Campbell, who had been sent by Jiaying to watch over Skye. Zabo realised that Jiaying and Skye were intending to leave him behind and in his anger, Zabo threw Campbell against a wall. Zabo was interrupted by HYDRA agents, and he told Campbell to get Skye away. He walked towards the agents, and attacked them. When Gordon came back to retrieve Skye, Zabo leaped at him and just managed to reach him as Gordon teleported away.

Return to Afterlife
"Ahh, didn't expect to see me back here so soon, did you my love? Not after such a well planned banishing!"

- Calvin Zabo to Jiaying

Zabo returned to Afterlife enraged and immediately began arguing with Jiaying about how she had planned to leave him behind like an unwanted dog. She tried to calm him down but he continued to shout at the top of his voice so everyone could hear, she eventually convinced him to wait in his room and calm his rage, telling him she would visit him later. Although he was unhappy, he knew Jiaying was often right in these situations and so did as he was instructed, leaving Jiaying to deal with the current situation. After spending a few hours in his room pacing up and down trying to calm down, Zabo was visited by Jiaying. She took him outside for a walk and Zabo tried to defend himself that he had come back too hot and had not had time to calm down, which is why he lost his temper. Zabo tried to learn why Jiaying had attempted to send him away, she tried to explain it was too dangerous to have him in Afterlife. She told him he could stay for the time being, which delighted him as the idea of spending time with his family made him incredibly happy. Jiaying then asked Zabo about Raina and he told her that they had spent a lot of time together and she was not to be trusted.

S.H.I.E.L.D. Threat
"The Index? Do they want to?.. No no no... They will brand you, all of you. You have power here, lots of it." "To do what? Openly attack them? Blast their planes out of the sky?" "Well for a start."

- Calvin Zabo and Jiaying

Raina and Gordon were sent on a mission to locate an ancient Kree weapon; Zabo was called into Jiaying's office once again to discuss Raina and whether or not this was a danger to the Inhumans. Zabo briefly threatened to rip out Raina's heart if she ever hurt his family, but quickly calmed down and told Jiaying how he had met her when she was a homeless young girl with no family, and how he witnessed her go from resourceful and wise to manipulative and selfish. He told her that he had never known Raina to not want something, leading to Jiaying asking him what he believed she wanted now. When Raina and Gordon returned having successfully located the Monolith in S.H.I.E.L.D.'s possession, Zabo was invited to the meeting to discuss their next step. Although Gordon argued that Zabo should not be involved, Zabo argued that he should be as his daughter was currently at S.H.I.E.L.D., Raina tried to calm Zabo down but only succeeded in annoying him further. Zabo began to mock Raina, claiming she was putting on an act and was likely making up many of her visions and was trying to control them to create chaos. Gordon began mocking Zabo being nothing without his formula. Jiaying calmed down the situation assuring them that they would not allow S.H.I.E.L.D. to bring down their civilization. Jiaying later informed Zabo that S.H.I.E.L.D. were coming to Afterlife to meet her, the idea put Zabo in a rage and he smashed a table with his bare hands, although he immediately apologised. Jiaying asked him if he believed she could trust S.H.I.E.L.D., although Zabo made it clear he despised S.H.I.E.L.D. and especially Coulson, he knew that Coulson did care greatly for their daughter. When she asked Zabo about the Index Zabo appeared horrified at the idea, telling her that S.H.I.E.L.D. would brand them and take away her power. He suggested she use her power to fight against S.H.I.E.L.D. but she insisted that that was not what Skye would want. Jiaying said that her people would never follow her blindly into a war, but Zabo insisted that he would. Hearing this, she told Zabo that even though he had aged, he was still the same bold man with whom she fell in love, and the two shared a tender moment. Seeing no choice Zabo suggested that she hand him over to S.H.I.E.L.D. as a gesture of good faith, allowing him to protect his family.

Returned to S.H.I.E.L.D.
"You know I was always excited to meet you, even when you were a little bit of nothing inside your mother's belly. I had all these ideas in my head of what kind of woman you'd turn out to be. You really are magnificent."

- Calvin Zabo to Skye

Zabo was present when Robert Gonzales arrived in Jiaying's office for a meeting, when he asked why Zabo was present, Jiaying explained that she was willing to hand him over to S.H.I.E.L.D. as they had willingly handed Skye and Lincoln Campbell back to them, when Jiaying mentioned that Zabo had killed his agents, Zabo insisted that he had not, although he admitted to having killed many other people. Jiaying then ordered Skye to deliver Zabo to S.H.I.E.L.D. while she began her meeting with Gonzales. As they walked to the Quinjet, Zabo told Skye about how excited he had been to meet her, even before she was born. He expressed his gratitude to having been able to meet and spend time with her and she told him she was grateful that she got to know him as well. As Zabo was handcuffed and put onto the Quinjet, his pockets were searched by the S.H.I.E.L.D. agents aboard. One of the agents found the vials of his formula in his pockets, empty after he had injected himself earlier, when Anne Weaver asked him about it he denied all knowledge, as they were put away Zabo watched the agents with a strange smile on his face. As his formula began to take hold, Zabo struggled to keep his sanity and began singing children's songs to himself while tied down and wearing noise-cancelling headphones. Although he could not hear anything, Zabo knew that Jiaying's plan was under way, as many of the S.H.I.E.L.D. agents appeared distressed and at one point, Melinda May was returned unconscious to the Quinjet. Zabo was taken back to the Playground, where he was greeted by Phil Coulson. Coulson demanded to know why Zabo was really there but he insisted he was simply a peace offering sent by his family. Coulson then had Zabo locked in a cell.

Questioned by Phil Coulson
"You're here to take out some S.H.I.E.L.D. agents?" "No, I'm here to take out as many as I can."

- Phil Coulson and Calvin Zabo

Zabo, still suffering from the effects of overdosing on his Formula, found himself feeling extreme cold and extreme heat in quick periods. Phil Coulson arrived to begin questioning Zabo, who complained of the intense cold he was feeling, when Coulson asked why Zabo had surrendered, he responded by explaining that Coulson, not being a father, could never understand what a father would do for his child. Coulson began asking about how Zabo had managed to kill an entire village of people, Zabo simply told him he had done it with style. When Coulson returned to continue the questioning, Zabo was now suffering was intense heat and requested a glass of water which he poured over himself before requesting another glass to drink. Coulson revealed that Jiaying had assassinated Robert Gonzales with the intension of starting a war between S.H.I.E.L.D. and the Inhumans, but Zabo refused to believe him. Coulson asked if Jiaying had forced Zabo to inject himself with his Formula as part of the distraction. Zabo divulged to Coulson that it was a formula of his own invention, designed to enhance his strength in order to protect his family and he had taken it under his own free will with the intention of killing as many S.H.I.E.L.D. agents as he could. During their discussion, Coulson causally referred to Skye as Daisy, which threw Zabo into a rage as he felt only her family should call her Daisy. Coulson attempted to reason with Zabo, pointing out that everything he had done, including wiping out the village and taking the vials of his formula, was all on Jiaying's behalf, but Zabo refused to believe he was being manipulated by his wife, claiming that she was not a monster like him. As he grew more and more angry at Coulson's accusations, his heart gave out and Zabo went into cardiac arrest and collapsed.

The Monster
"You were looking for a monster?"

- Calvin Zabo

Zabo was rushed to the medical unit, where Jemma Simmons attempted to restart his heart. When the defibrillator failed to bring him back, Simmons was forced to use adrenaline to start his heart again. This happened to be the missing component the serum needed to work, and Zabo went into a seizure. The final dosage resulted in Zabo undergoing a physical transformation, causing his skin, veins and fingernails to grow to repulsive sizes and giving him the enhanced strength he desired. Coulson, Simmons and Leo Fitz tried subduing Zabo by locking him in the medical pod, but Zabo smashed through the enhanced glass with little effort. They then attempted to stop him by shooting him with I.C.E.R.s, but they failed to even slow him down. Zabo pursued the agents, wreaking havoc in the S.H.I.E.L.D. base until Coulson was able to pin him against a hangar wall with the S.H.I.E.L.D. SUV, reinforced with an Electronic Battering Ram. Coulson managed to talk Zabo down, expressing his opinion that Zabo was not a monster but a good man, acknowledging that everything he had done was out of love for his family. Zabo managed to free himself, but rather than attack, he agreed to work with Coulson to protect Skye. Zabo was put under armed guard while Jemma Simmons helped counteract the effects of his formula, resulting in the reversal of his physical changes. While he continued his treatment, Zabo overheard Leo Fitz informing Coulson that Jiaying and a team of Inhumans had successfully taken over the Iliad. It was decided that Zabo should join Coulson and his team on the mission to stop Jiaying, as he had an inside knowledge of the Inhumans which could prove highly beneficial and if need be he could be a highly dangerous weapon for S.H.I.E.L.D. to unleash upon their enemy.

An Impossible Choice
"Please stop. You don't have to do this, you don't have to live with that pain. I will." "Oh... Cal... what are you doing?" "Keeping my promise."

- Calvin Zabo kills Jiaying

As they approached the Iliad, Zabo realized that Jiaying's plan was to use deadly Terrigen Crystals to kill all the Humans on board. He then assured Coulson that he would deal with Jiaying, as he viewed it as a family matter. He told Coulson to ensure the crystals were safe while he dealt with Jiaying. Zabo soon found Jiaying attempting to escape with the crystals; he tried to reason with her by telling her to think of their daughter. Jiaying refused to listen and had Gordon teleport Zabo into a locked room, trapping him. Zabo soon escaped and found Jiaying and Skye outside the ship, both using their powers to try and kill each other. Zabo begged them to stop before telling Skye she did not have to live with the pain of killing someone she loved. Seeing there was no way to stop Jiaying, he pulled her away from Skye and broke her nerve endings. He then lifted her high in the air and broke her spine, killing her. As Jiaying died, she asked him why he had done this to her, and he replied that he did it to keep his promise to her of protecting their daughter. Zabo held the body of his beloved wife and cried as he took the pain of her death and suffered it, knowing that he had saved Skye from the same agony.

A New Beginning
"I know I'm going away for good, but I was hoping you might come visit, once in a while." "I will, I promise." "That would be..." "Let me guess, the best day ever? You have a lot of those." "No, just one. July 2nd 1988."

- Calvin Zabo and Skye

With the Inhuman threat at an end, Zabo left the Playground. As he was leaving, he was walked out by Skye. In their last few moments together, Zabo told her that she was better than he ever imagined, even though he had imagined her perfect. Assuming that he was going to be incarcerated for the rest of his life for his crimes, Zabo requested that Skye come and visit him at his prison, and she promised that she would, telling him it would be the best day ever. Zabo told her he had only had one best day, the day she was born. Zabo's mind was erased by S.H.I.E.L.D. at a request from Skye, using the remaining resources from Project T.A.H.I.T.I., and he was allowed to begin a new and happy life as Doctor Winslow. He began work as a veterinarian with his own office. As Winslow worked another day at his new building, welcoming new animals to his practise with a smile, he was visited by a young woman, who showed an interest in his business. Winslow greeted the woman warmly and she introduced herself as Daisy; Winslow noted that it was a lovely name before continuing his life as a happy and peaceful man.

Personality
Since experiencing the trauma of discovering the brutally murdered corpse of his wife and experimenting on himself, Calvin Zabo has demonstrated a highly unstable personality, easily prone to outbursts of rage, driven by a desperate motivation to restore the family he feels he has lost while seeking revenge on his transgressors.

Under normal conditions Zabo maintains a calm demeanor, expressing a high level of intelligence and a sensible, levelheaded personality, but at times may still express mild anger or annoyance in a more tactful manner.

Although Zabo was mentally unstable, he was also very caring; this was put forward by Phil Coulson who went on to say that he wore his heart on his sleeve. He ultimately only wished to fulfill his promise to Jiaying, which was to protect their daughter, which he made sure he followed to the point he even killed Jiaying herself because she attempted to murder Skye. This promise, however, made Zabo go to desperate lengths experimenting on himself and murdering an entire village of people.

Zabo's true self, however, was a much more caring and admirable man, a positive side of himself which most people who meet him find hard to believe, including his own daughter, who persistently called him a monster since their first meeting. As Calvin Johnson, he was a responsible and dedicated physician and worked for Doctors Without Borders. And were it not for their family tragedy, he would have been a wonderful father and husband as well. When Zabo showed his daughter around Milwaukee, he would continuously talk about how he planned on giving his family a normal and peaceful life, having already chosen a school for Daisy, and taking her to school and to dances.

After undergoing the T.A.H.I.T.I Protocol and having his memories wiped, he is now living happily as a veterinarian. As Dr. Winslow, he is very social and hospitable to others, and kind to animals. It can be assumed that Zabo has been restored to the good man he once was, albeit without the family he no longer realizes that he lost.

Powers
"If I wasn't born with Inhuman powers then I would make my own."

- Calvin Zabo


 * Enhanced Strength: Calvin Zabo shows physical strength that exceeds that of an average man, being capable of easily killing a man with his bare hands and breaking a HYDRA operative's neck by lifting him and tossing him on the floor. Derived from experiments Zabo performed on himself hoping to protect his daughter after her mother's death, his strength allowed him to toss a now transformed Raina to the ground, even though she had him by the throat, once he got enraged when she insulted his daughter.
 * Transformation: Thanks to his formula, Zabo can partially transform himself into a mostly huge humanoid, extremely resilient to physical damage: in this form, non-lethal weapons such as the I.C.E.R.s have absolutely no effect on him, and even lethal force barely slows him down. Also his strength increases remarkably, as he is able to toss around extremely heavy lab equipment with no effort, and was able to break Jiaying's neck with a simple twist of his wrist.

Abilities
"I can help. I'm a doctor."

- Calvin Zabo


 * Master Physician: Zabo has extensive medical training, having worked in a clinic in his youth, and having performed underground surgeries in his recent years. He possesses extensive medical knowledge regarding human physiology, which in turn makes him effective at saving lives, or killing others whenever he loses his composure. He has used his medical knowledge to create a chemical formula that enhanced his physiology and improved his strength, though he was not entirely successful with it, as it gave him a more violent personality.

Trivia

 * In the comics, Calvin Zabo is best known as the supervillain Mister Hyde, a recurring enemy of Thor and Daredevil, and father of superpowered S.H.I.E.L.D. agent Daisy Johnson. In the season two of Agents of S.H.I.E.L.D., he actually becomes a monstrous version of himself that alludes to the comic book character.
 * Zabo has a miniature hula girl on his desk, much like the one Skye had in her Van.

Behind the Scenes

 * Though the character's full name wasn't yet revealed in the series, it was confirmed by Maurissa Tancharoen that the character is Calvin Zabo.
 * Kyle MacLachlan did not play Calvin Zabo in the character's first appearance, Beginning of the End; the character was instead portrayed by a stand-in.
 * The actors of Agents of S.H.I.E.L.D. and the staff responsible for the marketing of the TV Series, suggest in social media that the character's alter ego is the same as in the comics. For example, a promotional art using the word "Hyde" instead of "hide", also promoted by Kyle MacLachlan with the description "You can run but you can't Hyde!", paraphrasing a statement attributed to American boxer.
