A Robot Arm is quite the eye catcher. All I'm saying is he's different enough, Roy and Jim were different enough that we didn't know that he was intended as a clone until Greg told us, Arsenal's different enough from Roy for the same reasons.

IMO, the baldness is a slight influence by Luthor through the arm transaction.
