Antiform

File:AntiForm.jpg

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 br 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.

There is also a rumor that there is a "White" Anti Form. This form is said to have a 1 in 1000 chance of appearing. The attacks are the same, but do twice the damage of the regular form. This is only a rumor; there are different stories, but none have been proven.

• Fights in which Anti-Form never occurs: Pete (all fights), Barbossa (Port Royal), Hades, all battles involving outside characters (i.e. Mickey, Hercules, etc.)
• Note: Once the scene where Sora battles Roxas (After you fight him in Final Mix+) has occurred, as long as the Two Across Keyblade, acquired from winning the battle and which bears the "Light and Dark" ability, is held, there is a 25% chance you will get Final Form instead. If you still get Anti-Form, it increases to 50%, and then 100%.

Trivia

• Anti-Form looks very similar to Anti-Sora in the first game (Kingdom Hearts), only without a Keyblade.
• While Anti-Form is normally impossible to activate manually, certain cheat devices can allow you to activate Anti-Form from the Drive Menu.
• During the fight against Vexen in Kingdom Hearts: ReCom(and his data battle in Kingdom Hearts II: Final Mix+), Vexen can make copies of Sora that are actually Sora's in Anti-Form.
• Despite showing almost no distinctive appearance apart from Sora's shadow, the Anti-Form's appearance does indeed changes in different worlds:

• In Halloween Town the Vampire mask takes the form of a Shadow Heartless.
• In Timless River, the Anti-Form appears as a retro cartoon silhouette.
• In Space Paranoids, the Anti-Form changes the armor completely black and the circuits to dark purple.
• In Christmas Town, the Anti-Form changes Sora's Santa costume completely to black, a Heartless emblem can be seen on top of the hat though. (Applies only in Final Mix)
