"Colossus", whose real name is unknown, was a member of the criminal band led by Nea and Nostrand.
Colossus was a member of Nea and Nostrand's criminal group. Apparently unsatisfied with what he received, he betrayed them during a bank heist, when he shot Nea in the head after she had cracked the vault. Taking the money and fleeing along their intended escape route, Nostrand discovered what Colossus had done, and attacked him. The two were captured as a result.
During transfer to the Dark Sentencer, Colossus repeatedly attempted to break free and attack the guards, each time unsuccessfully. He and Nostrand exchanged hostile glares throughout the trip, Colossus angered for their capture and Nostrand for the apparent death of his love. Taken before a judge, the two were sentenced to life imprisonment aboard the Dark Sentencer. During this, Colossus refused to kneel before the judge, and was knocked down by a guardsman.
Colossus, true to his name, was a tall, muscular man. His face was severely disfigured, with his right cheek torn open and his teeth exposed, some of them hanging out of the opening. How precisely he received this disfigurement is unknown.
During the heist, his face was covered by a skull mask, and he wore industrial style equipment.
