02In Hawaii, the octopus is an alien underworld god.
Kanaloa is one of the four major akua (gods) of traditional Hawaiian religion and ruler of the underworld. For leading the spirits in a failed rebellion, he was cast into the underworld. He did seem to get installed as a god, so it seems like something of a lateral move.
Depending on how you translate the Kumulipo, the Hawaiian creation myth, Kanaloa is basically the last alien survivor of a now-extinct age.
