~Obtain all Aeons~

This trophy requires Yuna to get all Aeon summons available in the game. You receive Valefor, Ifrit, Ixion, Shiva, and Bahamut as you go through the storyline. But to earn this trophy you'll also need to earn Yojimbo, Anima, and the Magus Sisters. Once you obtain the last Aeon you'll earn this trophy.

See It's All About The Money for Yojimbo details.
See Feel the Pain for Anima details.
See Delta Attack! for Magus Sister details.
