Dante Montero is my imagining of the main character from a fanfiction that I'm trying to hammer out ideas for.
He has control over supernatural powers that allows him to create weapons out of pure energy. He also possesses a fragment of metal from a demonic artifact that allows him to transform into an incredibly powerful demon. The Insignia on his back is the crest of his long dead family. The amazing thing is that he's only 21 years old.
