How to Get Final Form in Kingdom Hearts 2.5
In Kingdom Hearts 2, Sora has the ability to change into different drive forms by absorbing the power of his friends Donald and Goofy. The most powerful of these drive forms is final form. Final form allows Sora to attack very quickly with his keyblade, dealing tons of damage. It even allows you to attack while gliding.
You won’t pick up final form the same way that you do other forms in the game; the way that you earn it is actually quite hidden. You can only unlock the final form after you’ve beaten the Roxas boss in The World That Never Was. This is right at the end of the game, so this form is mainly for the final areas of the game or for post-game content, such as the game’s many superbosses. Once you’ve defeated him, you’ll earn a keyblade called Two Become One. After equipping this keyblade and activating master form, there is a chance that you will instead transform into either Sora’s anti form or his final form.
Luckily, there is a simple way to do this which removes the need to constantly refill your drive bar. Simply go to Olympus Collisieum (Hercules’ World) Underworld Entrance and talk to Panic. Select the Cerberus Cup. Use master form with the Two Become One keyblade equipped, and if you don’t unlock final form, pause the game and hit retry. This will refill your drive guage, allowing you to try as many times as you like until you get final form. You’ll know you’ve got it when Sora turns white. After you’ve unlocked final form, you will be able to activate it from the drive menu the same way that you do with any other form.
