Dream Eater

Dream Eaters (ドリームイーター) are creatures that debuted in Kingdom Hearts 3D: Dream Drop Distance. They reside in the Realm of Sleep and consume dreams, as their name implies. There are two types of Dream Eaters: benevolent Spirits (スピリット), which feast upon bad dreams, and malevolent Nightmares (ナイトメア), which plant bad ones. During their Mark of Mastery exam, Sora and Riku recruit Spirit Dream Eater to help them combat the Nightmares plaguing the Sleeping Worlds.

Story
Despite Ansem, Seeker of Darkness's defeat, some of the worlds remain asleep. Yen Sid explains they are beyond reach of the Heartless, but they and their Keyholes are instead threatened by Nightmare Dream Eaters. These enemies attack Sora and Riku many times over the course of their Mark of Mastery exam.

In Traverse Town, Sora decides to team up with Spirit Dream Eaters after he sees Neku summon a Necho Cat. Riku makes the same choice after Joshua helps him spawn a Komory Bat.

When Sora and Riku return to Traverse Town, they learn their friends in that world have forsaken their Dream Eaters for their human Game partners. The Keyblade wielders also encounter the Spellican, which wreaks havoc before escaping to Symphony of Sorcery. There, this powerful Nightmare troubles Mickey Mouse until Sora and Riku come to his aid.

In a false version of The World That Never Was, Riku comes face-to-face with Ansem, Seeker of Darkness. The Heartless reveals Riku is a Spirit Dream Eater who spent his entire Mark of Mastery exam inside Sora's dreams. Riku battles Ansem, defeats him, and escapes to the real The World That Never Was. He then locates Sora's Meow Wow and uses the power of his Komory Bat to reach the Castle That Never Was.

After an encounter with the real Organization XIII and Sora's successful rescue, Riku returns with King Mickey, Donald, Goofy, and Lea to the Mysterious Tower. To wake Sora, Riku voluntarily plunges back into his friend's dreams and defeats the Armored Ventus Nightmare.

Reawakened, Sora watches as Yen Sid names Riku a Keyblade Master. He returns to the sleeping Traverse Town and reunites with his Spirit Dream Eaters.

Design
Like the Unversed, Heartless, and Nobodies, Dream Eaters come in many shapes, sizes, and colors. They resemble real-world animals, and they bear emblems that designate them as either Spirits or Nightmares. While Spirit Dream Eaters are brightly colored, Nightmares are less vibrant. A Spirit Dream Eater's Disposition determines its eye color, while Nightmares' eyes are round, red, and lack pupils.

Characters that become Dream Eaters have emblems on their bodies in accordance with their roles. Riku, a Spirit Dream Eater, has the appropriate sigil on his back. Meanwhile, the Armored Ventus Nightmare has one emblazoned on its helmet.

Nature
Dream Eaters exist in the Realm of Sleep, where they consume the dreams and nightmares of its denizens. Nightmare Dream Eaters outnumber Spirits, which Sora and Riku must create by collecting the necessary recipes and dream pieces.

Spirit Dream Eaters enjoy affection and love playing with Training Toys. Their Disposition determines their eye color and how they behave during combat, while Paint Guns can be used to alter their body color. Spirits lend their power to Sora and Riku via the Link System, and they can compete against others of their kind in Flick Rush tournaments.
