Anathos is, according to Twilight who has a memory of all of Xaltanis` opponents, the strongest enemy Xaltanis has ever faced. It is never mentioned when Anathos was annihilated (it may be millenias or only decades on Fantasio). However, Anathos was the most evil god being at that time. It had the strength of a god, with huge powers that would have been unrivaled on Mobius. It has never been said whether Anathos was male or female originally, though the character picture Yorobot based this form on was male.
