Dark Matter (species)

Dark Matter is a species of beings who are often characterized by having a single eye. Most members are a major antagonistic force in various Kirby games. Although their goal may vary between individuals, most of them attempt to invade planets and cover them in darkness. Presumably being made of darkness and negative energy, some members are weak to light and positive energy, as shown with the Rainbow Sword and the Love-Love Stick. Members of the species also have the ability to possess and control others' bodies to do their bidding. In the past, Hyness's clan worshiped the "matter of darkness." This implies that the Dark Matter species (or the material they are made of) was worshiped by them.

Regular Dark Matter are the most common members of the species, given that they can be mass-produced by Zero as an attack in Kirby's Dream Land 3. They appear as a black sphere with a single eye and additional orange spheres surrounding their body.

According to General Director Shinya Kumazaki on Miiverse in the Kirby: Planet Robobot Drawing and Screenshot Challenge, Dark Matter have the ability to materialize their memories. This explains how the Dark Matter Clone is able to wield the Rainbow Sword in Kirby: Planet Robobot.

Dark Matter
There is a specific character also named Dark Matter who has made a few appearances in the Kirby franchise, most notably his debut appearance in Kirby's Dream Land 2, where he is the main antagonist and the final boss. Dark Matter's true form (often referred to as Real Dark Matter) is identical to the species themselves, but he has a distinct form known as Dark Matter Blade, who has a somewhat humanoid appearance and wields a sword.

Gooey
Gooey is a docile Dark Matter that is friends with Kirby, being introduced in Kirby's Dream Land 2. Gooey is very much unlike other members of the species, despite being made of the same material as them. He has two eyes instead of one, a mouth with a long tongue, and can use Copy Abilities like Kirby. Gooey does have a similarity in that he can take flight via his Mock Matter form, where he resembles Real Dark Matter and can use their lightning attacks. However, he retains his normal face.

Zero
Zero is the leader of the Dark Matter species, or at least the leader of most members, serving as the main antagonist and true final boss of Kirby's Dream Land 3. Zero is shown to have the ability to create Dark Matter, meaning that it is the presumed spawn of them. Zero mainly attacks by shooting blood at its opponents, and can also detach its eye from its socket as a last resort.

Dark Rimuru, Dark Rimura, and Dark Rimuro
Dark Rimuru, Dark Rimura, and Dark Rimuro are a trio of Dark Matter that appeared in Kirby 64: The Crystal Shards. They were the ones who shattered Ripple Star’s crystal and forced Kirby and friends to gather the Crystal Shards. They are not technically fought directly, instead possessing a Waddle Dee, Adeleine, and King Dedede and making them fight. After Kirby defeats and frees the victims, the trio fly off and are never seen again, leaving their fate unknown. Their appearance is vaguely similar to a Real Dark Matter, and much like regular Dark Matter, they look identical to each other.

Miracle Matter
Miracle Matter is a supposedly elite member of the Dark Matter species. Unlike other members, Miracle Matter's body is covered with eyes. It is shown to have the ability to take on different forms that have the same powers as Kirby's Copy Abilities in Kirby 64: The Crystal Shards.
