I was told that Anima was a Final Aeon, and to be honest I kinda thought he was too because I used Anima against Jecht and they were both equally the same size and wielded power unlike anyone else in the game, with Anima's help I took Jecht apart in less then 15 minutes.
Anyway my question is if Anima was indeed a Final Aeon then why the heck didn't Seymour use him against Sin? He could've defeated Spira's worst enemy all along.

The "becoming Sin" thing probably came later as he grew older.
