i see your poin but greiver is linked to squall where the other GFs arent obviously linked to anyone. there are some theorys on eden and i think that square based some of the GFs on the game possibly.
heres one thought. how did ultimecia even know that greiver was what squall considered to be the most powerful thing in existence? 3possibilities.
1. she is rinoa and has been frozen or somehow kept alive until this time and has gone insane but still remembers what squall thinks is the most powerful monster. (im not a supporter of the R=U theory so dont flame me for this. im just looking at things from every viewpoint.)
2. she used some sort of sorcery to read his mind or something.
3. she looked at his necklace. which would explain why the greiver (in some peoples opinion.) doesnt look much like the thing on the necklace
then again i doubt squall made greiver up all by himself. there are bound to be books and stuff that have legends about greiver.
