[[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 shadow [[Keyblade]]. After being defeated, it fades back into darkness.

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, and it has the Heartless' trademark glowing yellow eyes. It wields a shadowy copy of the [[Kingdom Key]].

In [[Link Mode]], the second player's avatar is depicted as a darker version of Sora. Just like Shadow Sora, it lacks the yellow eyes of the Heartless, but can still wield a Keyblade like AntiSora.

It is recommended to set [[Aero]], [[Cure]], and either [[Thunder]] or [[Stop]] to the shortcut menu. Most of AntiSora's attacks resemble Sora's basic ground combo, using a vertical slash, a horizontal slash, a thrust, and a turning slash. It is unable to use magic or Special Abilities, but can melt into the shadows and move around like [[Shadow]]s. It can leap out of the ground with an uppercut, dealing massive damage if Sora is caught. Avoid these attacks with [[Dodge Roll]] or by keeping Sora in motion.

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 Sora. [[Scan]] can distinguish the real AntiSora from the fakes because the fakes have 1 HP whereas the real AntiSora still has the full HP bar, but the fakes can hit and do the same amount of damage as the real AntiSora. Be sure to keep Sora's HP within a tolerable level—heal when necessary.

[[Guard]] is particularly useful if used in conjunction with [[Counterattack]] in this battle, as Sora can deflect some of AntiSora's attacks.

During the final portion of the storyline, Riku performs a Dive into Sora's heart in a sequence resembling the Dive to the Heart sequences from ''Kingdom Hearts''. In this sequence, numerous AntiSoras appear as enemies after Riku has tagged at least 10 Soras. Each is surrounded by an impenetrable blue energy shield when it first appears and will slowly circle the screen, occasionally launching a large X-shaped attack directly forward. Eventually their shields will drop, at which point they can be killed for health pickups, but fighting the AntiSoras is not required to complete the Dive. These versions of AntiSora have the same visual and sound effects as Dream Eaters when they get destroyed, despite having the same eyes as that of a Heartless.
