An Extra Equestrial (E.E.) is a term for creatures from outer space in Fallout: Equestria - Ballad of a Crystal Pony. They may also be called Aliens. No such creature has been encountered in the story, but the character of Clash Coat has been called one by DJ Pon3 as an attempt to classify her when she is glowing like a crystal pony. DJ Pon3 has also said there are rumors of a downed E.E. ship south of Siren Cave.
