The history of the old Justice Force coincides with the Mirage template, but with some modifications. As first seen in Return of the Justice Force, Steve has feelings for his teammate Battling Bernice (who also had feelings for Dr. Dome). Bernice secretly had a daughter with Dr. Dome, Ananda. But when she fell in battle, the Justice Force went their separate ways, as their own adventures entered comics; coincidentally, Steve and Metal Head ran their own comic store in Northampton, Massachusetts. It was mentioned in one issue that Stainless Steel Steve once saved Dr. Dome from Living Volcano and another issue having Dr. Dome curing Stainless Steel Steve of the creeping alien rust.
When the Domeoids kidnapped the former Justice Force members, Steve and Dome accused each other of being behind of the attacks, but in reality, they were caused by Ananda, who blamed the Justice Force for the death of her mother. The turtles and Casey Jones, had joined Steve in search of his friends, and Michelangelo tried to bring the counter-parties back to their senses.
After she had filed her thoughts of revenge, Ananda and Metal Head joined the second incarnation of the Justice Force.
Back to the Sewer
Although because of his age Steve can no longer be actively involved in the Justice Force, he and Zippy Lad are in the second incarnation of the team as advisers on the side.
Stainless Steel Steve has a round metallic saucer on his forehead, which he gets his name from, capable of smashing through anything, as well as withstand any blow to the head. Steve mostly uses it as weapon offset by objective headbutts; the plate is very resistant against physical damage and if in the right position is able to fracture even stone, steel and bullet-proof glass with a single blow.
He speaks in an Adam West-style voice.
