Origin

Patrick O'Connor was an American air fighter. While stationed in London, he became a test subject for the stolen German technology, with which the Germans had created their Battleships and Panzermensch. He survived the experiments and became their first HMH (Her Majesty's Human).

Taking the codename Colossus, his first fight was again Battleship Sieglinde. She had invaded Paris with a troupe of Panzermensch. Together with other enhanced humans, Colossus fought one-on-one against Sieglinde. Trying to choke her, she tore off both his arms and mutilated his body with her powers. Invulnerable, Colossus didn't die from the mutilation. The Allied Forces euthanized Colossus by using an industrial drill.
