Dark Matter is a major recurring antagonist from the Kirby series and considered by some to be the main antagonist.
In Kirby's Dream Land 2, Dark Matter takes over King Dedede and after defeating Dedede he shows his true form.. It flies up and Kirby grabs a sword and goes into space to fight Dark Matter's Swordsman form, taking on a strange mage-like form with a sword just like Kirby's. After beating that form, he turns into a single eye with manypetals, this is his true form.
Dark Matter Returns in larger numbers to flood Pop Star in Kirby's Dreamland III. In this game Dark Matter is presented as a species, presumably led by Zero. In Kirby 64: The Crystal Shards, they return once more. The Dark Matter Cloud and Zero Two are destroyed in this game, presumably destroying the race as a whole.
Dark Nebula from Kirby: Squeak Squad is known as Dark Zero in Japanese, is likely it is a type of Dark Matter. It was later revealed to be true in 2015 by the creators.
Darm Matter returned in a non-canon spinoff from Kirby Mass Attack, he was a villain encountered in Kirby Quest. This game also featured the return of his Swordsman form.
Dark Matter Swordsman returned in Kirby: Planet Robobot, albeit as a clone. Star Dream summoned him to test Meta Knight in Meta Knightmare Returns. Some of his attacks use the Rainbow Sword, the weapon that originally destroyed him. He was also fought in The TRUE Arena back-to-back with the Queen Sectonia clone.
