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, 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, Ross' life was saved by Hulk. Afterwards, she and Banner went their own separate ways. In 2018, Ross was a victim of Thanos' Snap, but was resurrected by Bruce Banner five years later.
