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.

Development
Tetsuya Nomura designed the Meow Wow; the others were designed by other staff members. Several Dream Eater designs were scrapped, but the Queen Buzzerfly was revived as a boss.

Kingdom Hearts χ‎
During the "age of fairy tales", the Master of Masters creates the first Spirit Dream Eater, the Chirithy, to assist and guide Keyblade wielders in their endeavors. The Master of Masters warns the foretellers that if a Keyblade wielder succumbs to darkness or vanishes, so will the Chirithy. The Chirithy support all five Unions, and though they are not subordinates to the foretellers directly, they work together with them to drive back the darkness.

<!--What does most of this have to do with Dream Eaters? Player meets Chirithy in Daybreak Town, who informs them how to wield their Keyblade and earn Medals. Afterwards, Chirithy teaches Player how to access the Gates to travel to other worlds that are also afflicted with darkness. Nightmare Chirithy proclaims that Nightmares like it exist to show people bad dreams, allowing them to sever connections and live freely, a concept that Chirithy is unable to understand. After a fierce battle with Darklings, Nightmare Chirithy absorbs them and becomes a monster. After being defeated, Nightmare Chirithy fades away.

After a reluctant Player takes part in the Keyblade War, they collapse in exhaustion following individual battles with each of the foretellers. Chirithy joins them, embracing Player as the countless hearts stop flying into the sky above them. A bright light then surrounds Player and Chirithy, with Ephemer and Skuld emerging from it in order to save Player by guiding them into the new world alongside the rest of the Dandelions. Upon entering the new world, Player and the other Dandelions forget everything about the world they had left behind, as Ava had intended, with only the new Union leaders and the Chirithys retaining knowledge of the world they left behind.

The new Union leaders enact a Union χ that allows each of the Unions to interact with one another, as they are determined to ensure that the Keyblade War never occurs again. The Union leaders decide to celebrate their success by creating new Spirits for the Dandelions. As a result, Player and Chirithy encounter another Chirithy sent by the Union leaders, who uses Chirithy's fur to craft the new Spirit, whose purpose is to further aid Player in battle and help defend against Nightmares.

When Player starts to have nightmares about the Keyblade War, reliving the fated battle and his confrontation with Aced, Chirithy reports this to Ephemer and Skuld. While reluctant to lie to Player, Chirithy wants Player to forget about the world they had left behind. With encouragement from Skuld, Chirithy resolves to continue protecting Player. Ephemer reminds Chirithy to inform Player about the Union χ while he and Skuld will investigate an impending darkness in the new world. Accepting this, Chirithy returns to Player.

After Player awakens from another nightmare in the Enchanted Dominion, Chirithy becomes concerned of the increasing frequency of Player's dreams of the Keyblade War. Player asks why they were asleep in the Enchanted Dominion, which Chirithy concludes it was due to the fact that Player has been through exhausted due to their recent activities. Chirithy inquires if Player they have become more open-minded while being in a new world and reminds them to rest regularly during their adventures.

As Player and Chirithy travel through the forest, they stumble across a castle entwined in a thicket of thorns. Unable to advance further, Chirithy suggests to Player that they head back to Daybreak Town and come back when they have figured how to clear the path. As Maleficent's Raven flies overhead toward the castle, Chirithy comments on how it would be nice if they had wings. -->

Kingdom Hearts 3D: Dream Drop Distance
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.
