Anti Black Coat

The Anti Black Coat is a Nightmare Dream Eater that appears in Kingdom Hearts 3D: Dream Drop Distance. He is the physical manifestation of a nightmare that has trapped Sora.

Kingdom Hearts 3D: Dream Drop Distance
The Anti Black Coat appears when Riku tries to wake Sora from his deep sleep. He battles the Keyblade wielder and vanishes upon his defeat.

Design
As its name suggests, the Anti Black Coat wears a black coat. Its circular, red eyes are visible from underneath the coat's hood. It bears the Nightmare Dream Eater insignia on its back and magenta flame designs on its sleeves and coattails.

Attacks

 * Wild Arcanum (ワイルドアルカナム): A six-hit melee combo.
 * Poison Arrow (ポイズンアロー): Launches a series of curved projectiles that inflict Poison when they make contact.
 * Scissor Bite (シザーバイト): Strikes vertically (from below) or horizontally with an "X"-shaped mass of red and black energy.
 * Shadow Steal (シャドウスティール): Knocks the target upwards with a vertical blade erupting from a dark red line racing through the ground. The red line will constantly aim at the target. If the hit lands on Riku, the Anti Black Coat will deplete his HP to 1 and scatter HP orbs across the arena to heal himself. The HP orbs that he grabs heal around 1/5 of his current HP bar each. Riku's HP will stay at 1 until he gets freed, even if he eventually gets healed by his Dream Eaters in the meantime.

Strategy
Riku should maintain a hit-and-run/block strategy when fighting the Anti Black Coat, as the Nightmare attacks every time Riku staggers him. He can avoid a majority of the boss's attacks with well-timed Dodge Rolls or Dark Barrier. To damage the boss, he should rely on using his commands like Balloon spells or Shadowbreaker at the right moment mostly when the Nightmare is close and not about to teleport. Curaga is essential during this battle as well, for it can quickly replenish Riku's HP if he is hit by the Anti Black Coat's "Shadow Steal" technique, that can be avoided by either blocking or dodging forward. The Nightmare can use this technique at any random moment, noticeably when combined with other attacks or when he is idling, and if he follows this attack by any other one while Riku is getting freed, it can become a guaranteed Game Over. Provided Riku has Once More and Second Chance equipped, the HP orbs that are spread across the battlefield can act as a failsafe in case Curaga is still in cool down or if Leaf Bracer isn't equipped. Riku may as well combine Doubleflight followed by Firaga Burst and Ice Barrage for a temporary safe spot, making him avoid most of the boss's attacks while dealing major damage.
