Purified Griever.

I always had this headcanon, that the Griever Ultimecia summoned in the final fight, was just a corrupt/copy, and the true Griever was Squall all along. So of course I included it in my main Squall/Sora AU.

See in the AU, Squall and his friends were sent through the time distortion after defeating Ultimecia, and ended up in the kingdom hearts world. Unfortunately Sophia, Seifer, Zell. Quistis, Laguna, Irvine, and more were reverted to younger ages and lost their memories.

Squall however has remained the same age (17) since he was sent through the distortion later and retained his memories. Anyway, later on in the AU Ultimica shows up, crazed and furious, yelling at Squall that she wants Griever back, and Squall is like WTF are you talking about?, and then fighting ensues.

And then at some point Squall becomes Griever and kicks her ass with Sora’s help.
