Bad Ending (Obtained when lost to Shuiyn) : When you party all dies and you lose to Shuyin, This Ending Appears. Venagun is done charging and the Spira is destoried by the Blast that is done.

Normal Ending (Finish the Game) : You beat Venagun and then this ending plays, this ending only happens if you less than 80% of FFX-2 completed, the scene ends up with Yuna flying on top of the Celisus with Rikku and Paine, Tidus does not appear.

True Ending (Complete with 75% or more) : The real ending, Yuna and Rikku and Paine go back to Besaid, and they find Tidus swimming to Besaid.

Ulimate Ending (100% Complete) : The ulimate ending, Yuna and Tidus at Zanarkand, and they discuss the real truth behind how Tidus is real or not, this is the best ending but, this has problems, if you really want to see it, complete the game 100% and see it but if not, you aren't missing out on alot.
