Betty Ross

"You made him a fugitive... to cover your failures and to protect your career. Don't ever speak to me as your daughter again."

- Betty Ross to Thaddeus Ross

Doctor Elizabeth "Betty" Ross is a scientist and professor at Culver University, who became infatuated with her colleague Bruce Banner. In 2005, she joined Banner in the Bio-Tech Force Enhancement Project, administering Banner with a primer she developed that allowed him to survive his exposure to gamma radiation and become Hulk. For five years, she was separated from Banner, while her father Thaddeus Ross spearheaded an international manhunt.

In Banner's absence, Dr. Ross had begun dating Leonard Samson. In 2010, she became an accomplice of Banner after she was reunited with him in the United States. Together, they went on the run from the Strategic Operations Command Center, until Banner was captured in New York City while consulting Samuel Sterns. During the Duel of Harlem, when Banner was released to fight the Abomination, Dr. Ross' life was saved by the Hulk. Afterwards, she and Banner went their own separate ways.

In 2018, she was a victim of Thanos' Decimation, but was resurrected by her former love interest five years later.

Early Life
Elizabeth Ross was born the daughter of Thaddeus Ross. Her mother died of unrevealed causes. Later, Ross met Bruce Banner in college, where they fell in love. At Harvard University, both participated in an experiment involving hallucinogenic drugs.

After college, Ross and Banner both worked at Culver University as scientists and professors, with Ross teaching and Banner working in  and.

Gamma Experiment
"The gamma pulse came from the amygdala. I think Dr Ross' primer lets the cells absorb the energy temporarily, and then it abates. That's why you didn't die of radiation sickness years ago!"

- Samuel Sterns to Bruce Banner

As a response to the, General Thaddeus Ross commissioned the Bio-Tech Force Enhancement Project, designed to recreate Abraham Erskine's Super Soldier Serum from World War II. Both Dr. Ross and Bruce Banner were recruited into the program, although they were not informed of the serum's true purpose, instead of being told that the serum-treated radiation sickness.

While working on the project, Dr. Ross developed a myostatic primer that allowed an individual's blood cells to absorb gamma radiation temporarily. Banner, who had substituted the original serum's Vita radiation with gamma radiation, injected himself with both the primer and his replicated serum and increased the dosage in gamma radiation in an effort to impress General Ross.

Dr. Ross' primer allowed Banner to survive the tremendous amount of radiation he was subjected to, as it allowed Banner's cells to absorb the excess amounts of gamma radiation. However, this caused Banner to transform into a giant, green monster. With no control over the beast, Banner destroyed the lab, attacking Dr. Ross and injuring her, and as a result, was hospitalized.

Following her recovery, her father ordered that the data regarding the project was to be deleted, forcing Dr. Ross to covertly extract the data and keep it hidden, in the event that Banner would require it someday. While being separated from Banner, Dr. Ross moved on and began dating Leonard Samson, one of her colleagues at Culver University.

Bruce Banner's Return
"Don't go. Don't go. I want you to come with me now. Please."

- Betty Ross to Bruce Banner

Bruce Banner eventually returned to Culver University, but not with the intention to meet Ross. She however accidentally saw him at a pizzeria owned by Stanley Lieber during a dinner date with Leonard Samson and convinced him to stay the night, giving him a copy of the gamma experiment data that he required.

Battle at Culver University
"You're killing him! Stop! Get off of me! Bruce! Bruce!"

- Betty Ross

The next day before Banner left, Samson informed General Thaddeus Ross that Banner and Dr. Ross had reunited and that they were headed to Culver University. A battle ensued on the university campus which lead to Banner transforming into Hulk. During the battle, Hulk connected with Dr. Ross on multiple levels, as he realized that she was the only one without the intention to hurt him. This resulted in his anger increasing when he saw Dr. Ross being hassled by the Strategic Operations Command Center. After Hulk had defeated the general's forces, including super soldier Emil Blonsky, Dr. Ross approached him, being the only one who was not hurt in his presence. When a military gunship arrived and fired at both Hulk and Dr. Ross, Hulk shielded her from the gunfire as well as the helicopter's explosion. He then carried her unconscious body to safety, hiding within the Smoky Mountain National Forest.

Aiding Banner
"I don't know. In the cave, I really felt like it knew me. Maybe your mind is in there, it's just overcharged and can't process what's happening." "I don't want to control it. I want to get rid of it."

- Betty Ross and Bruce Banner

Upon gaining conscience, she connected with Hulk, with Hulk demonstrating the intent to protect her in the face of the thunder and lightning of a nearby storm. Ross calmed him, sitting beside him and holding his hand. Due to his calmed condition, Hulk changed back to Banner overnight. Later, the pair stayed at a motel for some time, where Ross wished to have sex with Banner, but he refused, citing that his heart rate would get too high if he became excited, triggering his transformation into Hulk. After procuring him with some clothes and leaving every traceable possession behind, Ross sold her mother’s last remembrance, a necklace, to help the pair to travel to Grayburn College in, New York City, and meet Doctor Samuel Sterns, a close ally of Banner under the moniker "Mr. Blue". However, General Thaddeus Ross had hacked the S.H.I.E.L.D. database to track all communication between Banner and Sterns and discovered Sterns' location. Upon arriving in Harlem, Betty and Banner met with Sterns who tested his experimental antidote on him. During his transformed state, Hulk was at the verge of losing control and destroying the laboratory, only to be calmed by Dr. Ross, who managed to prevent Hulk's thrashing long enough for Sterns to administer the antidote, allowing Banner to briefly control the Hulk before reverting back to his human form.

Duel of Harlem
"It's okay." "Betty."

- Betty Ross and Hulk

However, soon after, the Strategic Operations Command Center intervened, arresting Banner and taking the pair back into custody. On their way back to base, the soldiers reported that Hulk had been spotted in the streets. General Thaddeus Ross, Banner, and Dr. Ross realized that it was a transformed Emil Blonsky. Banner requested that Ross let him attempt to stop him, to which the general grudgingly complied. A battle between Hulk and Abomination ensured throughout the streets of Harlem, where Abomination was able to best Hulk, causing Banner to briefly regain control. As Abomination pinned Hulk and informed him that he would kill Dr. Ross, Hulk regained control and managed to defeat Abomination, while also saving both the Rosses from an explosion. Hulk prepared to strangle Abomination to death but elected to spare his life upon Dr. Ross' pleading. She and Hulk shared a brief moment together, in which he spoke her name and wiped her tear, before fleeing as more authorities arrived.

A Gift from Banner
While visiting the sometime after, Dr. Ross began reflecting back on her memories with Banner by looking back at some pictures of him stored on her camera. Thirty-one days later, Banner, now in hiding at Bella Coola, British Columbia, Canada, purchased Dr. Ross' necklace from the pawn shop and arranged for it to be mailed back to her under the pseudonym "David B".

Death and Resurrection
In 2018, Betty Ross was among those killed by Thanos in the Decimation. She was resurrected by Banner five years later.
