Nightmare Moon

A powerful alacorn princesses of equestria that made it night now corrupted with power and greed. She is tall easily double the hight of the average pony with a taste for revenge on those who banished her long ago. Shes so well known across equestria she has her own holiday: nightmare night. This being equestrias equivalent of Halloween ponies offer candy to her to satiate her for the time being. Her anger and cruelty may be strong with her night based magic but shes fair and dosent act out for no reason. She can grow to the size of a castle if she wants to to intimidate or show her power. With her hunger for both power she seeks out large sources of magic to consume however she also hungers for the one thing she cannot resist from her past: candy! But after years of offerings of candy her pitch black belly has started to gain more pudge creating a furred dome that hangs under her. She refuses to admit that she has a gut usually acting annoyed at those who point out her tummy. However she cant help her greed if offered candy and will quickly eat it right out of someone's hoof then looking offended for someone using her stomach against her. Despite her villainous ways and clearly corrupt power hunger deep down shes still that princess so it is possible to get through to her if someone tries hard enough. She may even become there friend "begrudgingly" though in her mind she will appreciate it due to years if isolation.
