Kingdom Hearts 2

Below I have given some brief information regarding the drive forms and their uses.

Brave Form (Valor)

While in this form like your others you change your appearance and gain new abilities. The Brave form has the advantage of the High Jump Ability. While in this form your speed and strength also increase. You obtain this form very early on in the game, just after you gain control of Sora in fact. This is the easiest of the forms to level up because you only need to hit an enemy to gain experience points.

Wisdom Form

This form is no where as fun as the Brave form, the first difference between this form and the others is you only wield one keyblade. However while in this form instead of sword attacks you shoot plasma out of your keyblade. This form is very hard to level up early in the game because it requires you to kill a heartless to gain experience points, so if you are really weak it may take up a whole drive duration just to get a few experience points. This form yeilds the air-slide abilitiy.

Master Form

The Master form is the most fun to play with until the end of the game of course, but until then this will do. While in this form you are considerably stronger and very fast, you will be able to destroy a handful of enemies at one time with the whirlwind like ability. This form is rather easy to level up, an experience point is gained for every small drive ball and 3 for ever large drive ball. The leveling of this abilitly yields the Air Dodge ability which is extremely useful.

Final Form

This may not be the strongest drive form, however the Air Glide ability is so awesome that even if it isn't gliding pwns. In this ability you basically float around at very high speeds slicing the hell out of everything and anything. The only downfall is to gain 1 experience you have to defeat a nobody, and later on in the game when their are plenty it is still very time consuming.

Anti-Sora Form

The most annoying form on earth, this form can occur for various reasons and is really not preventable. In either case this form depleats your drive form and you cannot even get out of it once you are in it like the other forms. You are sort of trapped in an insanly fast heartless version of Sora. You are not offense-less but when you don't gain any experience what is the point of even fighting.
