Lets think of some things here…
Tidus, loving Yuna and all that junk, would probably be the person to step up. It would be a dramatic scene as it would be Father vs Son here. Tidus would look… well… pretty funky as an Aeon if I think about it… I mean, what can he do as an Aeon?
Auron is well…. dead… so I guess he won’t count.
Wakka was with Yuna for quite awhile and he would take that nobel stand. As an Aeon, well, he’ll probably be something pretty big.
Kimahri… well just make him bigger and he’s already an Aeon.
Lulu…. gawd…. hottest Aeon ever? Probably, I think her rack would kill the entire FFX party. She might be second in line for being an Aeon… or maybe Third.
Rikku… ahh…. somehow I doubt it.
What do you guys think?
The thing I wonder most is – after killing Yunalesca, what if they had found out that they couldn’t kill Sin any other way?
I think Kimahri would have become the fayth. It makes the most sense. Of course everyone would offer, but after realizing the truth and everything, I think Kimahri would be the only one still willing. Plus I doubt Yuna will let anything happen to those she loves (Wakka, Rikku, Lulu, and Tidus).
You make it sound as if she’s just taking advantage of Kimahri. That’s true though, Kimahri would be the most willing out of them all.
I see Kimahri as being the most likely one as well. He’d definitely volunteer for it, and while I am sure it would pain Yuna to do it, i think she would understand why he made that choice.
I do think a Tidus vs Jecht type thing would have been spectacular, but I can’t really imagine him being the one.
