Referred specifically as "The Steve" by the teenagers, he is considered the leader of the Teen Ninjas. Maybe teens altogether. His first and only appearance was in Operation: T.R.E.A.T.Y., where he and Numbuh 362 were to sign the "Don't mess with us, we don't mess with you!" treaty between kids and teens. His clueless persona was seen briefly until he unveiled the plan to betray the Kids Next Door using a specialized piece of rock music to get rid of them, showing a more deviant side worthy of a leader.
