When you say third male character, is this going be an extant character or an original one?

Also bear in mind that all of Ultimecia's GFs could exist in the present as well as the future (Tiamat, etc...), so theoretically two characters could have the same GF!

As for the other GFs I consider any of the summon monsters from any FF game cannonical. I included Diablos in my FFVI fanfic. Just because they don't appear in the game doesn't mean they don't exist.

In which forum will your guide be?
