So I decided to make an OC. His name is Umbra, he's a thief and he's able to use magic to stretch his body in a way that makes him look like a shadow. Honestly, he seems kinda OP to me so I don't plan on using him in any RPs. He's supposed to be the antagonist in a story I'm writing.
Not sure what to make his cutie mark yet. I was gonna make it a bag of money jumping out of a chest, but can there be a cutie mark for theft? Is that allowed?
Hopefully he's not too similar to anyone else's OC.
