Tartarus
The primary antagonist and self-proclaimed God of Demons. Tartarus destroyed Earth in the original timeline and was instrumental in pressuring the other gods to force Zephyr's reincarnation—mainly because he wanted to erase that blemish from his otherwise perfect track record. He's obsessed with maintaining his image as an all-powerful being, which makes his failure to prevent Zephyr's initial escape a sore subject. Fans often note that his vanity is arguably his biggest weakness, even more than his actual combat abilities.
