- "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[src]
Dr. Elizabeth "Betty" Ross is a scientist, as well as a professor at Culver University. She is Bruce Banner's former girlfriend, but rarely gets to see him since his exposure to Gamma Radiation, turning him into the Hulk.
Betty was assisting Bruce with the Gamma Pulse experiment that resulted in the unintentional creation of the Hulk: a large, strong, green, being that Bruce, from that moment on, would turn into when his heartbeat got too fast or when he becomes very angry. The resulting accident in the lab caused Betty to be injured and taken to the hospital. When she awoke, she found that Bruce had already left. Bruce later quit his job and left in search of a cure to his unwilling transformations.
When Betty returned to work, her father, General Thaddeus Ross, had all of her work and data on the Gamma Pulse experiment taken away, but she had already made a back-up version in case Bruce would ever come back.
Bruce eventually returns to Culver University, but not with the intentions to meet her. She however accidentaly sees him, and forces him to stay the night, giving him a copy fo the gamma experiment data that he required. The next day before Bruce left, Leonard Samson informs Gen. Ross of his presence. A battle ensues on the campus of Culver University which leads to Bruce transforming into the Hulk. During the battle, Hulk is shown to connect with Betty at multiple levels, as he realizes that she is the only one without the intention to hurt him. This results in his anger increasing when he sees Betty being hassled by Army Soldiers.
With the fight over, Betty approaches him, being the only one who was not hurt in his presence. Hulk ensures her safety when a helicopter crashes upon them, and takes her in the mountains after she passes out. Upon gaining conscience, she connects with the Hulk as no one had ever before, with the Hulk demonstrating the intent to protect her in the face the thunder and lightning of a nearby storm and Betty calming him, sitting beside him and holding his hand. Due to his calmed condition, Hulk changes back to Bruce overnight.
Later, the pair stays at a motel for some time, where Betty apparently wanted to have the connections with Bruce, but he pulled back, as it excited him to the level which might change him into the Hulk.
Leaving every traceable possession behind, Betty sells her mother’s last remembrance, a necklace, to help the pair to travel to New York City, and meet Dr. Samuel Sterns (Mr. Blue), a close ally of Bruce. Bruce underestimates the track on him, and his email to Mr. Blue is easily traced by S.H.I.E.L.D., who then responds to the U.S. Army and General Ross.
Helping Bruce find an antidote
Upon arriving in New York, Betty and Bruce meet up with Dr. Sterns, who tests his experimental antidote on Bruce. During his transformed state, the Hulk is at the verge of loosing control and destroying the laboratory, only to be calmed by Betty, whose interaction and soothing words to the Hulk makes him control his anger and change back to Bruce, there by, allowing the antidote work.However, soon after, the U.S. Army intervenes, arresting Bruce and taking the pair back into custody. On their way back to base, Army soldiers report them that the Hulk has been spotted in the streets. General Ross, Bruce and Betty realize that he is a transformed Emil Blonsky. Bruce request that Gen. Ross to let him attempt to stop him, to which the general grudgingly complies. A battle follows in which The Hulk falls weak in front of the now improved Blonsky, only to beat him when Blonsky’s actions endanger Betty’s life. After beating Blonsky, Hulk and Betty share a peaceful moment together, in which he calls her name, and then flees as more authorities arrive.
Later, Bruce, now in hiding at Bella Cooper, British Columbia somewhere in the mountains, manages to retain Betty’s necklace, and arranges it to be sent back to her.
