Arakacians

Arakacian is the alien species, located in Oroboris from the universe of Heavy Metal. It is the same species, that Sage Odin belongs in, who is also one of the tertiary antagonists of the animated film, "Heavy Metal 2000". It is also Odin's true form, as he first takes the appearance of a mystic, to trick the heroes. The true form of Odin is featured briefly in the last events of the second part of Disney vs. Non-Disney Villains War.
