I have a theory about Ultimecia... (Major Spoilers)

[Carl the Llama]

Griever may be a GF but it doesn't function like the other normal GFs. Griever is more like a symbol of character or simply put, a very special GF. To summon this special GF, you need to have a stronger magic, such as Ultimecia's power.

Seeing as you always ignore my soundly given arguments I will just say this: Where is your proof?

I could make up stuff if I liked, like say... "Ultimercia is really a MAN with big hairy balls" but without a shred of evidence I can't prove it.

Please Note: I only accept real evidence, not convoluted backwards and insideout theories but SOLID PROOF, like say, Ultimania or some game script.
