Dream Eater

The Dream Eaters (ドリームイーター) are a species of creature introduced in Kingdom Hearts 3D: Dream Drop Distance. As their name suggests, they reside in the Realm of Sleep, where they consume dreams. Dream Eaters fall under two major categories, Nightmares (ナイトメア), which eat good dreams and plant bad ones, and Spirits (スピリット), which only eat bad dreams. Nightmare Dream Eaters serve as the primary enemies in Kingdom Hearts 3D: Dream Drop Distance, while Spirits serve as recruitable allies that Sora and Riku can collect.

Story
Following the defeat of Ansem, Seeker of Darkness at Sora's hands, a portion of the worlds attacked by the Heartless remain submerged in sleep. Though this means the Heartless cannot reach them, they are instead plagued by Dream Eaters, entities produced by the darkness present in these specific worlds and who seek the worlds' keyholes. Two kinds of Dream Eaters are produced: benevolent Spirits and malevolent Nightmares, constantly in conflict with each other.

Sora and Riku, as part of their Mark of Mastery exam, journey into the Sleeping Worlds to awaken them, in the process recruiting several Spirits to help them in their quest and battling and destroying Nightmares.

Following Young Xehanort's defeat at Riku's hands and the end of the exam, Sora finds himself reunited with all of his Spirit friends in Traverse Town, having given them access to the Realm of Light.

Design
Like the Unversed, Heartless, and Nobodies before them, the Dream Eaters come in a variety of sizes and shapes, although they appear to have a much higher range of color schemes than their predecessors, and often resemble animals; some resemble plants. Some of them have repeditive names based on their form, such as Komory Bat. Each Dream Eater is adorned with an emblem which signifies whether it is a Spirit or Nightmare. None of the Dream Eaters possess weapons other than the natural abilites their bodies give them; the Nightmare that possessed Ventus's Keyblade Armor is an exception due to using Sora's Keyblade.

Dream Eaters are characterized by having colorful appearances. Nightmares tend to have darker color schemes, while Spirits have lighter, pastel colorations. Nightmares also tend to have round, red eyes which lack pupils, while those of Spirits tend to be yellow, blue or green; purple is also one of the occasional colors as well. They usual materilize through violet smoke.

The symbol of the Spirit Dream Eater is present on the back of Riku's third outfit to symbolize his presence inside Sora's dreams; the reason being is that he became a Dream Eater in a sense, destroying the Nightmares that spring up in his friend's dreams. Lastly, the symbol of the Nightmare Dream Eater appears on the visor of Ventus's Keyblade Armor when it is possessed by a Nightmare with Sora inside it; it also becomes covered in darkness, becoming completely black. This would be the only Dream Eater to have a single color for its entire body.

Nature
Dream Eaters exist only within the Realm of Sleep, feeding on the dreams and nightmares of those who sleep. The Nightmare Dream Eaters seem to be much larger in population than the Spirits, who only appear in small numbers to assist Sora and Riku.

Dream Eaters do seem able to process simple emotions; at the very least, they can show loyalty, as they do so not only to Sora and Riku, but others like Neku as well. Dream Eaters also seem to react to various forms of treatment, appearing to be happy when they are shown affection. The level of emotion Dream Eaters can process seems to be on level with that of normal domesticated animals. It is unknown whether Dream Eaters consist of a heart, body, and soul like typical denizens of the Realm of Light do.

Spirit Dream Eaters are able to share power with one another and with other beings they are loyal to in a variety of ways. Sora can utilize his companions in a combination attack similar to the Limits of Kingdom Hearts II, while Riku is able to harness their power to perform stronger attacks. Nightmares are not seen to share powers with one another, though it is possible that they have the ability to do so and simply choose not to.
