Equestrian Legends/YMMV

Villain Sue: One of these attempted to sneak in, early in the site's history: a Germane Unicorn with Celestia-like powers, who could not be harmed by anything, served Discord with utter loyalty and was his right claw pony, had been alive for several thousand years, needed neither sleep nor food, and could spontaneously catch fire when he got upset because "it looked intimidating." Unfortunately, since the user deleted all his threads and account due to the character's denial the whole thing has become something of a noodle incident.
