Red Hulk

General Thaddeus E. "Thunderbolt" Ross is a fictional character appearing in books published by Marvel Comics, usually as an adversary of the Hulk, sometimes as a supervillain. Ross is a United States military officer, the father of Betty Ross, ex-father in-law of Glenn Talbot and the father in-law of Dr. Bruce Banner, who transforms into an immensely powerful monster known as the Hulk. To better combat the Hulk, he eventually allowed himself to be transformed into the Red Hulk by The Leader and MODOK.

A veteran of several wars, Ross was the military head of the Gamma Bomb Project although he treated the project's research head, Banner, with contempt. When Banner is caught in a test blast of the weapon and acquired his Hulk condition, Ross personally volunteers to kill the monster and pursues him with a growing obsessiveness. As he is not initially aware of the truth of Banner's condition, Ross merely suspects he is a compatriot of the beast. However, when he does learn the truth, Ross hunts Banner as well.

In 2009, Thunderbolt Ross was named IGN's 71st Greatest Comic Book Villain of All Time.

Ross is a General in the Air Force who is in charge of Bruce Banner's gamma bomb project. His daughter, Betty, takes a liking to the young scientist, a fact which only enhances the dislike the rough Ross has for the "weakling" scientist Banner. After Banner's transformation into the Hulk, Ross spends years chasing the monster, becoming obsessed enough with it to commit treason by allying himself with the Leader, MODOK and the Abomination in order to destroy the Hulk. Dishonorably discharged, he shows up at Betty and Bruce's wedding with a gun, and shoots Rick Jones. He is recruited by S.H.I.E.L.D. agent Clay Quartermain to merge with the electric creature Zzzax, a process that gives Ross superpowers, but also makes him mentally unstable. He is later restored to human form but retains some residual energy-generating powers.
