Fables version of the big bad wolf, the one reborn would have all his powers, though the wolf side when taking over would be his pure instincts and could only turn back by sleeping or until he masters his abiltys.
Honestly it's a cool character, and being the big bad wolf in any world would be fun, though I lean towards rwby, I mean Ruby is basically red riding hood so maybe he could save her and accidentally be her guardian angel that no one believes in.
