Onyx
Onyx was a Neanderthal from the stone age who was accidentally brought forward in time by Bloodhawk. Upon arriving, an unnamed symbiote tries to bond with him, but is too weak to fully corrupt his mind. Over the series, Onyx eventually learns to speak English. He often says that he feels drawn to the symbiote army, but cannot tolerate their destructive ways.
