Gen. Thaddeus E. "Thunderbolt" Ross is a fictional character and villain who appears in comic books published by Marvel Comics featuring the Hulk. Ross is a U.S. military officer, the father of Betty Ross, ex-father-in-law of Glenn Talbot, father-in-law of Dr. Bruce Banner, and the head of the gamma bomb project that turned Banner into the Hulk. After the creation of the Hulk, Ross pursues the creature with a growing unhealthy obsession, and, after learning that Banner and the Hulk are one and the same, Ross hunts Banner as well, spending years chasing him to the point of committing treason by allying himself with supervillains such as the Leader, M.O.D.O.K. and the Abomination to destroy the Hulk. In 2008, Ross was transformed into the Red Hulk in an attempt to better combat his nemesis.
