This is Ajax Reus!

He is a winged Tiefling variant.

Ajax is an only child. He is a Semi-god, his mother being a Tiefling and his father being a Demigod of Fire.

But he was too human to be accepted by Tieflings, too Tiefling to be accepted by Humans, and not divine enough to be accepted by the Gods or their Kin. So his mother, Memoris, hid him and raised him in secrecy in a rocky cave within the mountains.

When he was 7, he developed his fathers fire feet, which his father had inherited from his divine father (Hephaestus). But because god powers dilute every generation, the best his fire feet can do is melt snow that he is standing on, so they're basically there for appearance.
