Dark Matter are a hive minded race and major antagonists in the Kirby series. When a large group of Dark Matters join together, they form the Dark Star, an entire planet composed of pure darkness. Their main goal is unknown though they seem to want to spread their kind throughout the universe.
They first appeared in Kirby's Dream Land 2, where a sole Dark Matter possessed King Dedede and broke the rainbow bridges connecting the Popopo Islands, but was defeated by Kirby. Their next appearance was in Kirby's Dream Land 3, where they launched an all out invasion on Popstar.
Dark Matter BladeThis Dark Matter appears in Kirby's Dream Land 2 as the main antagonist. It was named in the game Kirby: Planet Robobot. In the manual it is stated that it targeted Dream Land because it grew jealous of its lifestyle and the fact that no one wanted to be its friend. It possessed King Dedede and shattered the rainbow bridges that connected the islands of Dream Land in order to take them over. After defeating the possessed Dedede, Dark Matter retreats. If Kirby has collected all of the Rainbow Drops, then they will form the Rainbow Sword and Kirby will get to fight Dark Matter. After defeating his first phase, he will reveal his true form. After being defeated, it explodes.
If Kirby hasn't collected all of the Rainbow Drops and defeats Dedede, then the bad ending plays out. Dark Matter remains in the king's body while Kirby and his animal friends go on a victory march through the rain. As Kirby, Rick, and Coo leave, Kine will linger behind and stare at the sky, as if sensing that something is wrong. Dark Matter also appears at the end of the scrolling list of enemy names in the credits, presented in a cross between its swordsman form and true form, listed as "!?".
Dark Matter Blade later returns in Kirby: Planet Robobot as a clone created by Star Dream to fight Meta Knight. This form fights exclusively in the swordsman form used by the one in the first phase of Kirby's Dream Land 2. This is due to Star Dream being unable to comprehend the alien nature of Dark Mind's true power, resulting in it never fully transforming into its eyeball form in its battle with Meta Knight. it does, however, briefly assume this form in its death-throes, just before it explodes.

Zero Two is the true main antagonist and final boss of Kirby: The Crystal Shards and a revived form of Zero. He initiates an all-out attack on the planet Ripple Star, in order to steal the Crystal Shard. This crystal can easily purge Dark Matter out of person, but it must be used in the hands of a good-hearted person or else its power will not work. Zero Two sent several Dark Matters to destroy the crystal so that it won't impede their plans. But a fairy named Ribbon takes the crystal to Popstar where Kirby lives. She is chased by three Dark Matters who shatter the crystal, unintentionally sending Ribbon to Popstar, where she meets Kirby. Meanwhile, a Waddle Dee, an artist named Adeleine, and King Dedede are all possessed by the three Dark Matters. Kirby easily defeats them, thus turning Adeleine, Waddle Dee, and King Dedede back to their normal selves. They all together travel other planets, recovering the pieces of the Crystal. They then go to Ripple Star, which is under control of Miracle Matter, a high-ranking Dark Matter subspecies. Kirby fights Miracle Matter and defeats him.
After Miracle Matter is defeated, the Dark Matter surrounding Ripple Star seemingly vanishes and peace returns. However if the player has collected all 74 Crystal Shards, then the Crystal will still sense some dark energy, and shoots a beam of light out at the Queen Fairy, turns out to still be under the influence of Dark Matter. After being blasted, the Dark Matter inside the Queen transforms into the Dark Star and begins its final assault.
Kirby, Ribbon, King Dedede, Adeleine, and Waddle Dee travel to the core of the planet to defeat Dark Matter once and for all.
Once they reach the center of the cloud, they find Zero Two and engage him in a fierce battle. Ribbon picks up Kirby, armed with Ribbon's Shard Gun, and flies him around as they fight Zero Two in a Star Fox-like fashion. After hitting Zero Two in the eye enough times, Zero Two reveals his weakness, a green, spiked tail. Kirby shoots the tail with shards and destroys Zero Two, finally ending the evil entity.
Although 02 was dead, other Dark Matters would live on to fight Kirby in later games.
Miracle MatterMiracle Matter is a special Dark Matter that can use some of the powers Kirby can conjure. Miracle Matter was assigned control of Ripple Star when Dark Matter took it over, but was later defeated by Kirby.
Miracle Matter possesses several of powers Kirby uses: fire, ice, cutter, bomb, lightning, needle, and stone. All of them are really powerful and very hard to dodge. But the ability it uses is also its downside, as it can take damage by the same element it uses at the time. Attacking it with a different ability than the one it uses will not damage it.

Main Article: Dark NebulaDark Nebula, also called Dark Zero, is the ruler of the Underworld and the true main antagonist of Kirby Squeak Squad. Although he was never seen associating with Dark Matter, he was confirmed to be a member of their species in the 20th anniversary encyclopedia. Before the events of the game he was sealed inside a chest though was later released when Daroach opened the chest, expecting to find a strawberry shortcake. After being released, Dark Nebula possessed Daroach, transforming him into Dark Daroach, and flew off into the galaxy with Kirby in pursuit. After defeating Dark Daroach, Dark Nebula flew off in the form of a small star. Kirby chased him down and defeated him.

In what is seen as one of the darker points of the series, a possessed King Dedede fights Kirby in both Kirby's Dream Land 2 and Kirby's Dream Land 3, possessing many surreal abilities such as his stomach opening up to create a mouth, spitting out balls of Dark Matter, and floating without having to puff up. Defeating King Dedede once all 7 Rainbow Drops (KDL2)/30 Heart Stars (KDL3) have been found reveals Dark Matter as the true final boss of the game, and the source of Dedede's powers.
In Kirby 64: The Crystal Shards, King Dedede is fought very early on in the game, and is possessed by Dark Matter once again. His attacks are similar to the ones from previous games; using his hammer and spitting out Dark Matter orbs.
In Kirby 64, Dark Matter possesses a Waddle Dee (who ends up being Kirby's friend). Waddle Dee's strength doubles during the fight, as well his physical features of having two eyes changed to one big single eye like that of a Waddle Doo. Dark Matter leaves the body after the battle and Kirby is reunited with his Waddle Dee friend.
In Kirby's Dream Land 3, Whispy Woods gets possessed by Dark Matter and is boss of Grass Land. He has the same regular attacks and moves, though after damaging him halfway he pulls his roots out and chases after Kirby.
In Kirby: Squeak Squad, Daroach was possessed by Dark Nebula, transforming him into Dark Daroach.
