Charon is a deity from Greek Mythology who ferries the dead to Hades. When people died, two coins were placed on their eyes for them to pay for a ride from Charon. He is widely depicted as being tall and skeleton like, carrying a large oar to paddle his boat. Michelangelo depicted him as being apelike.
He appears as a boss in God of War: Chains of Olympus and he rode Perseus to Medusa's lair in both installments of Clash of the Titans.
