ultima_(fft)
Primary antagonist of FINAL FANTASY TACTICS.
Previously localized as Altima, before the War of the Lions re-releases.
She has two forms. The first (and most popular), the High Seraph, is of a succubus-like woman in a red leotard with silver/white hair, red eyes, angel wings and head wings.
Her final, monstrous form, the Arch Seraph, resembles a gigantic suit of skeletal armor with bat wings. (e.g. post #304581)
