William "Bill" Foster, also known as Giant Man is a inventor, engineer and superhero who took part on many exploits of Doctor Henry Pym during his days as Ant-Man. A scientific and engineering genius, Bill found himself working alongside Nighthawk and Iron Man to save the life of Ant-Man after he was trapped on the Quantum Realm alongside Wasp. When Ant-Man was saved, Bill received a position in Pym Industries, when he would later become the hero Goliath. When Project: Meta was a success, Bill figured out he also wanted to help his country in the wake of World War III, so he entered on it under the counsel of Pym himself. After receiving his powers, Bill became Giant Man, the giant-sized counterpart to Ant-Man himself.
