Achilles is Apollo's right hand man. Artemis' mercy often makes him annoyed and he is conflicted by it. He is a Cyborg in the shape of a panther who carries a long sword and shield that can fire energy blasts. He also has acceleration mode which is activated by the balances on his shoes, unlike in his molar like 009 and 002. He is defeated by 009 with some help Pan.
He, like his other Cyborg's named after the Greek gods, had their memories erased. Their creator felt that memories would weaken their ability to fight.
