Thomas Stuart was the son of prison warden Tyler Stuart who was fired after Carl Lucas (who went on to become the superhero Luke Cage) escaped from prison. Thomas sought revenge on Cage and first ambushed him during his fight with Billy Bob Rackham, but managed to flee when Cage confronted him.
He returned, partnered with his brother Tim, sporting futuristic equipment, calling himself Stiletto. They were defeated by Cage and taken into custody by their father.
He eventually battled alongside his brother again (both serving Hammer) against Iron Man.
