This was really fun to do! There is a back story of course, so I had better get on to that I suppose...
This is one of my OCs- Sabre. His story is that he wants to be with his girlfriend, but, because of his magic (yes he lives in a world full of 'angelica Panthera' that all have magic powers) he is afraid he will hurt her. He is a 'insert catchy name because I haven't thought of one yet' which means he changes into a cool powered up version of himself once a month. The problem is in this form he cannot control his actions and basically kills stuff. (spoilers but at the end of the story he kills his gf by accident)
