Anti Black Coat
Kingdom Hearts 3D: Dream Drop Distance
As its name suggests, the Anti Black Coat wears a black coat. Its circular, red eyes are visible from underneath the coat's hood. A Nightmare Dream Eater emblem appears on the Anti Black Coat's back, and magenta flame designs decorate its sleeves and coattails.
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. Note that 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.
