History
Metalhead was once a superhero who, along with his friends Battling Bernice, Stainless Steel Steve, Zippy Lad, Dr. Dome, Captain Deadbolt and Joey Lastic founded the Justice Force team. Unlike his friends, Metalhead was not a man but a synthetic being that had been created by Doctor Dome. Finally, the Justice Force separated due to internal tensions simmered over Bernice because of the feelings of Dome and Steve, Steve and his friend Metalhead made ​​it to Northampton and opened a comic book store.

One day, the ex-members of the Justice Force were attacked by Doctor Domes old Domeoids, because Doctor Dome wanted to draw Bernice out of hiding. Bernice's daughter, Ananda was able, however, to inform dome that Bernice had already died three years earlier, and thus bring him to his senses.

Much later, Casey and April asked Steve and Metalhead to watch their adopted daughter Shadow after her grandfather Antoine Puzorelli had repeatedly tried to seize his granddaughter. The two super heroes then moved into the Jones farm, which they have shared with Shadow and Splinter (until his death).
