The ferryman named Karon is an interesting character from Secret of Mana.
Charon helps you cross the Sea of Wonders into the Moon palace.
But because his sprite is the same as a Robin Foot, the game recognizes him as an enemy.
You can't kill him with weapons but magic can kill him.
Obviously the Robin Foot enemy sprite that Karon has is based off of Robin Hood.
Karon, however, is based off of Charon the ferryman from Greek mythology.
Charon would let the dead cross the river Acheron to the underworld of Hades, a place of gloom and doom, if they paid him a silver coin.
Karon, though, let's LIVING people cross a desert in a SANDSHIP for FREE. But they lead to the Moon Palace which has the troubled town music playing ("A Phantom and a Rose" is the song).
Karon also is aptly named after Pluto's moon, Charon. Which goes hand and hand when he crosses space to get to the MOON palace.
