Clearly, it is Squall's mother Ultimecia, trapped in time due to Time Compression. This obviously proves I, Future Esthar's theory, that in FFVIII, that Zell and Seifer had an illegitimate offspring; Rinoa, who, in turn, had buttsecks with Selphie, thus having the baby, NORG. NORG then morphed into a Wendigo, which, after getting hit with a magical attack, lands on his back and shots pulse ammo out of its mouth. One day after getting hit with Ultima by Quistis he shot out a pulse ammo, which missed, and hit into the lake, and the chemicals morphed into Ultimecia after thousands of years. Naturally explaining that R=U. Any questions?
