I just want to tell you something about my own charakter Lupin:
He is a normal red fox, who is big as a wolf and not only that is special about him!
He got a scar over his left eye, from a special cat who he loves very much, but she... well let's say that she can get pretty aggressive and is a tsundere.
The most important thing about him to tell is that he can use magic, it's destructive nature seems to get over Lupin sometimes, that is why he can be extreme brutal and reckless. This magic he uses is called "Cerberus Flame", which allows him to use white flames and controll them like he wishes to do. He can also controll what the flames are attacking and what things get damaged by them. This mean he could let the flames flow over your body, but you can't feel any heat.
This magic also allows him to be flames himself. This technique provides two more forms of himself:
1. The first form of him is like a battle form which allows him to appear as a big fox anthro, he gots pretty much offensive and defensive physical power in this form.
2. The second form is a huge three headed fox beast with enormous magical and physical power.
BUT in really bad situations of anger, dispair or sadness because he lost someone, he really likes, it can happen that his magic takes the lead and his magic becomes acts likean spirit and destroys everything. After that Lupin can't remember anything and he also loses pretty much power. If you see his eyes glows red, you know he can't controll his power any longer.
Normally he is pretty quite and don't often laugh or shows many emotions... except his love is around.
This was a short view on my OC Lupin the Fox
