Hardware
Hardware is the mechanic and weapons expert of Mon*Star gang. He is also considered one of the most important members of the Mon*star gang to the Silverhawks.
Hardware's back history may be unknown, but unlike most of Mon*Star's lackeys he was never on the Penal Planet before episode "The Hardware Trap, Part 2" and also gets along well with locals at Fence. That suggests that he is also knowledgeable about avoiding authority. He is the source of most of the mob's weapons and technology, and has created some of the most dangerous problems for the SilverHawks. As he was the one who created Sky Shadow, he is presumably the one who also created the Mob member's bird partners.
