Kingdom Hearts II is it possible.....

.....to go into the final battle without having glide or arial dodge? cuz in the part of the fight when you have to dondge the buildings flying at you if you fell you wouldnt be abble to get back up cuz one time out of curiousity i went down under the dragon and theres no way to get up. that i saw anyway.

 

Of course it's possible, don't worry about that!

 

you have to have it in that little bit of the fight but after, if the ability is unactivated then ya don't.

 

You don't need it for the fight, you have the most powerful versions of them just for that fight. You don't need to have them beforehand.

 

you also get a more powerful dash. you know the ability from wisdom form.

 

You do get them, only for that particular final battle segment. That's the case in KH2, and I can only assume KH2FM as well.

Also, sora-final-riku mentionned a more powerful Quick Run. I think that's half-true, because the game's physics are very different in that part of the final battle. Quick Run sometimes makes you take off the ground, for example.
If you let yourself fall into the void, you'll... touch an invisible floor.

And half the time, I get stuck in a wall with lasers shooting be and bypassing Once More :ranting:
