Demi-fiend

A being whose the destiny to shape the new world was forced upon. No longer human...yet not a devil, The Demi-Fiend forges his own path.

Neither Man, Nor Demon
The Demi-Fiend 's purpose in the Vortex World was to find a reason and shape the new world with his power. Yet Demi-Fiend rejects being a puppet, despite being his designation, and wants to forge his own path, be it clinging to his humanity in fear and leaving the world a desolate and dreadful nest of demons, courageously recalling his humanity and returning the world to how it once was, or embracing his demon side and discard his humanity, rejecting all creation, and becoming the Champion of Chaos against the Legion of God.

Reject his demon legacy, or throw away his humanity? The Demi-Fiend has come looking for answers.

Season 3
Apparently in TFRverse, Demi-Fiend chose the path to restore the world how it once was, which also allowed him to keep his demon powers. However, he felt a voice calling him to the ring, where he found a strange blue-haired man, what could he possibly want with the Demi-Fiend?
