How Can I Get Thundara on kingdom hearts 2 (Ps2)?

Question

im really trying to beat this game i need your guys help plz help me

Answer 1

To obtain Thundara, you need to defeat the Storm Rider in The Land of Dragons on your second visit there.

Answer 2

You don't get it directly but once you have thunder and you get another thunder element its upgraded to thundara

To get thunder element #1 you must defeat the Hydra in the Olympus coliseum

To get #2 (thundara) Defeat the storm rider (huge flying bird) in the land of the dragons (2nd visit i think)

To get #3 just for future reference (thundaga) defeat the groundshaker in the pride lands (2nd visit)
