I really don't think there's any just cause to be calling this 'design theft'.
It's a pretty generic design; just by typing 'black and red wolf' into google you'll find a bunch of characters with similar, if not exactly the same markings.
In the future, if you think something is art theft, please simply report the post and leave it for a moderator to deal with instead of doing it yourself ^___^; That's what we're here for
