The problem is that we don`t know much about Ultimecia; she`s sort of like a small detailed character represented in the game and ironically she's the most type of villain that the game has to offer (main villain). Where does that leave us then? What do we know about Ultimecia? Almost nothing, just her sneaky dialogues and so many visible things around herself (her castle, possessions, images, etc.)

So, that's what the dragon's for.

NOT!
Irrelevant, because Ultimecia wasn`t involved in that incident. She was responsible for the appearance of Iguion. Like I said before, Ultimecia's data is so small, therefore questions arise and that only works if you like the game.

I haven`t thought about the Seifer part, it's possible but nevertheless it's a good attribute for the theory.

Who are you trying to tell someone what to do? This game is one of my favourite games, I like to explore and discuss when I'm bored. You`re implying that the game is straightforward when in fact it's not.
Iguion was of course a monster, just like other monsters in the game but it was under control of Ultimecia. Keep that statement in mind and compare it with the fact that her data is so small and you get the result.
Matron? I think you mean Ultimecia!
