Dark Matter is an evil force in the Kirby series. The entity is a massive black cloud that possesses or corrupts unsuspecting individuals. Dark Matter can also split into smaller entities with the appearance of an eye. The master of Dark Matter is Zero.
Dark Matter has the ability to possess a living, or in some cases non-living, creature. The creature becomes subserviant to Dark Matter, and may even gain some new dark abilities. In ancient times, Dark Matter simply corrupted living beings, rather than fully possess them. It has also been reported that Dark Matter can coagulate into bigger, more powerful beings.
In the fourth installment of the Dark Matter saga, Dark Matter again takes control of several planets. However, the action is spearheaded by Demons under the control of Mind Matter. It is also revealed that Dark Matter is very ancient. The latest incarnation of Zero, the Iron Soul, is defeated by Kirby and friends.
Dark Matter once again returns, but this time reaching out from the most remote regions of the galaxy. The evil force desperately searches for artifact, which it can use to become more powerful.
In a similar vein to Kirby 64: The Crystal Shards, multiple peaceful lands have been taken over by Dark Matter, however, this time, the overtaken areas are instead in an alternate dimension. Despite that, Dark Matter seems to be slowly infiltrating through portals in order to reach Pop Star. This is implied to have happened in the bad ending, as the exit portal appears to be overlooked by a gigantic blob of Dark Matter. In the final main world (Articulated Airship), it is shown that Dedede has once again been possessed. In this game, Dark Matter-infested creatures are shown to have a single eye instead of two eyes (in Dedede's case, he appears to be sleeping, though there is an eye within his stomach, similarly to Kirby's Dreamland 3). Another reincarnation of Zero appears in this game, known as Dark Zero.
A witch tried to resurrect it. She failed.
It appears as a collectable trophy in the game.
Dark Matter is the main villain of the story mode who stole the golden stars and attacked Kirby. Later, he meets Lavora the oldest Koopaling. In World 12, Dark Matter pulled Lavora to killing Kirby, but it didn't work. At the end, Dark Matter pulled into a Robo Dark Matter. He's afording to suck the whole Earth into his black doom! Kirby and Lavora sneeks into the machene and shuts down the robot. The whole thing break down and Dark Matter desides to kill them both himself! After the defeat, Dark Matter dissappears forever!
The species appear in the crossover Night And Night where they are forming as clouds so Nintendo Heroes Must Destroy them!
The true main antagonist of Kirby: Dream Land's Hope and (in a way) the final boss as it merges with Andaedra and becomes Dark Maiden. All of Dark Matter was sealed within the Lost Dimension after it was supposedly destroyed by Kirby. Andaedra traveled through the galaxy fighting any kind of its remains, looking for all of Dark Matter's concentration in order to destroy it properly. Dark Matter, however, managed to possess her, manipulating her into gathering essence of life to break it free and leading to the events of the game.
The battle takes place in an auto-sidescrolling road of obstacles, with Dark Maiden attacking from the background with varied dark magic, including dark energy balls, lasers and even summoned Dark Matter enemies. Occasionally, Dark Maiden will go into the actual stage and spin around in hopes of hitting Kirby, and will sometimes summon a replica of her sword made out of dark matter to swing around and attack.
The Void Matter Rift form is obligatory and given in order to counterattack her when she is in the background, sending attacks throughout the void rifts.
After taking enough damage, Dark Maiden goes into form 2, with Dark Matter mostly in control. With Meta Knight's assistance, Kirby flies and confronts Dark Maiden again. Similarly to 02's battle in Kirby 64, Kirby uses the Shard Gun given to him by Ribbon. It is essentially a shooting battle, and Kirby & Meta Knight must dodge Dark Maiden's attacks which consist in dark energy beams and blasts, summoning other magic through portals, etc. She also retains her ability to teleport around.
When defeated, the impact wakes up the cosmic guardian Zethdin.
