AntiSora

The AntiSora is a Pureblood Heartless that is found in Kingdom Hearts, Kingdom Hearts Final Mix and Kingdom Hearts 3D: Dream Drop Distance. It is a boss fought in the Captain's Cabin in Neverland and as an enemy in Dive to the Heart. Sora's Heartless also takes this form after being defeated by Data-Sora in his Neo-Darkside form.

Kingdom Hearts
Sora and his friends encounter Riku on Captain Hook's ship, where he reveals that he now has control over the Heartless. To prove it, he creates a Heartless replica of Sora before their eyes, and it throws them into the ship's brig. As Sora fights his way back to the ship's deck, he encounters many of these Shadow Sora's, which only he can defeat. However, they have no weapons and often vanish before he can even attack them. Once Sora reaches the Captain's Cabin, Riku creates a more complete replica of Sora, this one able to wield a shadowy Keyblade. After being defeated, it fades back into darkness.

Kingdom Hearts coded
Sora's Heartless evolves into Anti-Sora form after Data-Sora defeats its' Neo-Darkside form. It even gained the power to duplicate itself. Fortunately, Mickey helped Data-Sora when he was almost worn down.

Kingdom Hearts 3D: Dream Drop Distance
After Sora's heart is swallowed by Darkness, Riku dives into his heart and during his attempt to reach the Pillar is fought by many AntiSoras who dive towards him and shoot huge X-shaped symbols.

Design
The AntiSora is a near-perfect replica of Sora. It dresses in the same clothing as Sora, including his gloves, shorts, large shoes, hooded shirt, and even has the same necklace and hip chain. However, its clothing is colored entirely in shades of black and grey. Its skin is also black, as is its spiky hair. It carries a copy of the Kingdom Key, which is similarly dark-colored. It also has the glowing yellow eyes characteristic of Heartless.

The AntiSora's name reflects the fact that it is an antagonistic, Heartless copy of Sora. The prefix "anti-" means "against".

Strategy

 * Attacks
 * Keyblade Strikes: AntiSora strikes the player with its Keyblade.
 * Evade: The Heartless dives into the ground to avoid attacks.
 * Replica: AntiSora creates replicas to confuse the party.
 * Counter: Upon being struck, AntiSora dissipates into a mess of darkness, before reforming elsewhere and preforming a wide Keyblade swing attack.

The spells recommended to set to shortcuts are Aero, Cure, and either Thunder or Stop. AntiSora fights with many of the same skills and abilities that Sora uses. Unlike Sora, AntiSora is unable to use magic, but can instead transform into a flat shadow and move about in that state, much like the basic Shadow Heartless. It can deal a lot of damage if Sora is caught when it leaps back out of the ground. Be sure to keep Sora in motion or use the Dodge Roll ability to help avoid those attacks.

When the boss's HP meter goes to yellow status, it takes on a new strategy. In the second stage of the fight, AntiSora creates two replicas of itself to distract you. Use the Scan ability to find the real enemy, but be careful, as those replicas can hit and do the same amount of damage as the real AntiSora. Be sure to keep your HP within a tolerable level—heal when necessary. The Guard ability is particularly useful if it is combined with the Counter Attack ability in this battle, as you can deflect some of AntiSora's attacks.

Jumping on the bed on the left side of the room is a good place to avoid AntiSora's attacks or heal when necessary.
