General Thaddeus "Thunderbolt" Ross is the secondary antagonist of the 2008 Marvel film The Incredible Hulk and the 2016 Marvel film, Captain America: Civil War. He was a Lieutenant General of the United States Army. During his career, he was put in charge of the military project called the Bio-Tech Force Enhancement Project, which aimed to recreate the Super Soldier Serum. However, the experiment led to an accident which transformed the scientist Bruce Banner into Hulk. After a long hunt, Banner was captured, only for Ross' subordinate officer Emil Blonsky to transform into the monstrous Abomination which forced Ross to accept Hulk as an ally and allow him to escape after the battle in Harlem. Five years after this incident, he is now serving as the U.S. Secretary of Defense.
