FINAL FANTASY VII
An extraterrestrial life form that crashlanded on the Planet some 2,000 years before the events of Final Fantasy VII. It is an instinctual being that seeks to destroy. Shown below, are it's four forms: Birth, Death, Life and Synthesis.
(On the record, the creature is considered an it, but I've included it anyways because of the female forms it takes).
