I would really like to see FFXs Anima - simply because I could image her being a pretty cool fight, with possibly having the party split up to fight the upper and the lower body at the same time during certain parts of the fight.

And even if we're having creatures called "Valefor" already, we got hints that she could be come sort of summon during that quest with the Doman refugee kids. FFX is my favorite, so I'd really like for her to appear as a real, proper summon - and not only as some weird, demon-like creature in LotA...
