o yeah and what is the anti-form.

You pretty much have to beat everything. You need to complete the journal and do it on the hardest mode. I tried it and lost patience but I believe that is how you do it.

On hard you need to beat everything, on medium you have to beat everything and fill Jiminy's Journal...not possible in easy. Hope I helped.

On normal mode you have to complete the story 100% and complete Jiminy's Journal 100% and on Proud mode you have to complete the story 100% and this includes defeating Sephiroth and on easy mode it's not available. Also, Anti Sora is when you try to use your drive forms but instead transform in a heartless like state.

Secret Ending:
On Beginner Mode: You can't, tough luck.

On Standard Mode: You have to complete Jimminy's Journal. Yep, EVERYTHING! If there is a Mickey Head Icon in your start menu, then you know you've done it. It might be easier for some people to just start over on Proud Mode because...

On Proud Mode: You only have to complete all worlds. Yes, ALL, including the 100 Acre Wood and Atlantica.

You can fight Terra only in Kingdom Hearts 2 Final Mix. Once you've completed all worlds and watched the Old Secret Ending "Gathering",exit out to the World Map. There is a new episode added to Disney Castle. Head to The Hall Of The Cornerstone. Through the new portal, you can fight the Todomarishi Shinen(Lingering Spirit). If you do beat him, you get the Proof Of Connection.

Anti Form, also known as Anti-Sora, is Sora's Heartless Drive Form from Kingdom Hearts II. It happens based on a hidden counter that increases as you use forms (but drastically decreases every time you use Final Form), and has no abilities.

Most believe that this Drive Form exists due to Sora becoming a Heartless, specifically a Shadow. Since his movements in this Form are remniscent of that of Shadows and Neoshadows, this Drive Form is essentially the closest he ever gets to turning into a Heartless once more.

While Sora is extremely fast in this form, he can't attack with the Keyblade, instead he use his claws and feet, and can only revert when not in battle. It uses ALL of Sora's remaining Drive Gauge, and takes both party members. It also makes Sora more vulnerable to damage, and his attack power drops, but his combo length is longer than most other combos in the game (Final Form can get in more hits at its higher levels, but it is very fast, and ends quicker than the Anti-Form combo). Anti-form cannot be levelled up, and has no specific abilities, but pressing Square will make him do a Dodge to Forward Lunge attack (Anti-glide). One more threat is that Sora can't use magic or items, meaning he can't be healed.

Many say that the way to trigger the anti-form is by getting hit by heartless while in other drives, such as valor, wisdom, or master. The best way is using master form, because your party members are gone, and you can allow the heartless to attack you. You then gain points, which some call anti-points (not recorded in stats). When the anti-points go to a certain level, change into a random Drive, and then you will change into anti-form.

It is wise to not rack up anti-points before a boss battle because even though Sora deals lots of damage with Anti-form's long combo's, he is also more vulnerable to damage.
