How did general ross turn into red hulk?

General Thaddeus "Thunderbolt" Ross transforms into the Red Hulk due to exposure to gamma radiation. In the comics, he seeks power to combat the Hulk and undergoes an experimental procedure that grants him immense strength, durability, and the ability to absorb gamma energy. Unlike the Hulk, who grows stronger as he gets angrier, the Red Hulk's power increases with his anger, making him a formidable adversary. This transformation is part of a broader narrative exploring themes of power, rage, and the consequences of scientific experimentation.
