This fakemon is called Warloch (has two related pokemon in Sorceroast and Sagesage) I have a better fakemon idea, but I think this is a better place to start. Right one is the shiny version.
This is one of my fakemon ideas, only one so far that I've done art of because n0Rtist on youtube inspired me. Not my art, made by @knight-dude on tumblr.
