Character: unnamed black and red character (devil-vox)
It's quite possible that this character has a name, but this character was drawn by devil-vox around 2015, and all of his posts from Deviant Art, where he was active at that time, have been deleted. So if the character's name has been mentioned there, we can't know now.
I mean, it's possible to ask him the author, but at the point in time of writing this wiki entry, the name is unknown.
