General Thaddeus "Thunderbolt" Ross

General "Thunderbolt" Ross runs the gamma bomb test. He barks at Bruce Banner to speed up the countdown while waving off the caution of the world's foremost atomic scientist. He boasts that with him in charge the whole thing would already be over. Hi nickname becomes apparent as he is a blunt instrument in a general's uniform. He’s loud and certain, and has no idea that the timid scientist he just insulted is about to become the most dangerous thing the desert has ever produced.

Once the dust settles, Ross is less a soldier than a rattled father. Home with Betty, he brushes off her fear of the Hulk as an overactive imagination right up until the green giant crashes through his own doorway and seizes her. Afterward he can only hold his shaken daughter and make the one promise a man like Ross knows how to make. He will find the creature, he swears it.

General Ross commands the military response to the Toad Men's spacecraft. When the alien vessel is detected, Ross orders missiles fired at it. The missiles destroy the ship, causing it to crash in the desert. Ross and his soldiers surround the wreckage and discover Bruce Banner emerging from it. Ross immediately arrests Banner for treason, believing that Banner's presence aboard the alien vessel makes him responsible for the attack.

Ross continues directing military efforts while the Toad Men establish their invasion force. Betty attempts to convince him that Banner is innocent, but Ross remains focused on the evidence surrounding the crashed spacecraft. When Hulk escapes from imprisonment and reaches the Ross residence, Ross leads soldiers and a tank against him while Betty is inside. After Banner stops the Toad Men's fleet with his gamma-ray weapon, Ross participates in the aftermath in which Banner is cleared of treason, though Ross remains suspicious of the connection between Banner and Hulk.
