Dark Matter is a major villain in the Kirby series. He is controlled by O2. It is the main antagonist of Kirby's Dream Land 2, Kirby's Dream Land 3 and Kirby 64: The Crystal Shards. It is a shadowy sphere, with a single eye in the middle. It possesses someone (usually King Dedede) to help it with its goal.
In Kirby's Dream Land 2, Dark Matter had taken control of King Dedede. The only way Kirby could fight Dark Matter was to collect all of the Rainbow Drops and defeat King Dedede. Kirby would get a Rainbow Sword to fight Dark Matter's two forms with. Dark Matter's first form is a swordsman like being. It attacks by dashing forward trying to hit Kirby or by firing energy orbs. It can also fire energy beams from its sword. When defeated it turns into its real form and Kirby has to fight him again. This time it also attacks by shooting energy balls in a circular pattern.
Kirby's Dream Land 3Edit
In Kirby's Dream Land 3, If you were to collect all of the Hearts, you would then fight Dark Matter with the Love-Love Stick. If you defeated it you would then come face to face with Zero.
Kirby 64: The Crystal ShardsEdit
Dark Matter takes over the planet of Ripple Star and its population. Ribbon flies away on the power crystal which seems to be the only thing that can purge a Dark Matter from a victim without defeating the host. A few Dark Matter follow her and shatters the crystal into exactly seventy-four pieces. The three Dark Matter possess a Waddle Dee (coincidentally turning it into a Waddle Doo), a painter named Adeleine, and King Dedede (they join Kirby afterwards).
Dark Matter appears in the Kirby of the Stars Pilot as one of the enemies created out of the plumes of smokes when the sky went dark. It looks like the form Kirby first fights in Kirby's Dream Land 3. Kirby Freezes him with the Ice ability after he inhales the Ice Dragon.
