The worst thing you could ever do to your original character is giving him dark supernatural powers and an edgy personality, that has an abilities over everyone, and being more than average..
just
choose a random habit or talent.
look at Toy Maker, I made her also an example of a personality you could give to a character.
Trust me, even average or weakling character can be interesting.
When you give characters dramatic backstories and edgy personalities, they become less interesting and more cliche.
The characters who seem the most normal are the most interesting because they are relatable and therefore, memorable.
