Anti-Sora is a shadowy doppelganger of Sora, acting as a powerful boss in the Kingdom Hearts video game.
Anti-Sora can teleport in and out of shadows, duplicate itself and attack in a similar manner to Sora himself and comes with a considerable amount of health and attack power: like many doppelgangers Anti-Sora doesn't talk and is devoid of emotion, seeking only to destroy Sora and take his place.
The Anti-Sora 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.
When Sora encounters Riku on Captain Hook's ship, Riku reveals that he now has control over the Heartless. To prove it, he creates a Heartless replica of Sora before his 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 Soras, which only he can defeat.
However, the replicas 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.
- The Anti-Sora's name reflects the fact that it is an antagonistic, Heartless copy of Sora. The prefix "anti-" means "against".
- Anti-Sora is one of only eight enemies who do not have entries in Jiminy's Journal. The others are Bit Sniper, the Cave of Wonders Guardian, Chernabog, the Crank Tower, Glut, Shadow Sora, and World of Chaos.
