Other than Bandana Dee, another perfect playable Kirby representative is Dark Matter. He was the main antagonist of Kirby's Dreamland 2, 3, and 64 and was a true example of a villian unlike Dedede. It would be rather unique character for being a mixture between a swordsman and darkness user and the second genderless fighter. His abilities include possession, sword beams, teleporting, shooting dark matter clouds, black thunder, and sword rushing. It is the 5th most important and reoccurring character in the Kirby franchise. It was considered one of the hardest Kirby bosses in history and was considered the best thing that happened in the series. Even though it was created by a different director, there are some hints that Sakurai may have a soft spot for it. It reappeared in Kirby Canvase Curse, Kirby Squeak Squad, Kirby Super Star Ultra, and Kirby Mass Attack for the purpose of pleasing the classic fanbase. Most of his own villianous creations (Drawcia, Dark Mind, Magolor, ect.) are simialr to it in terms of attacks and appearances in all forms. Also it's master's (0) Zero Theme was in Brawl, as well as its heroic sibling's (Gooey) appearance as a trophy (Melee) and a sticker (Brawl). It may not be as popular as Nightmare or Marx, but is relavent to Kirby and has equal amount of chance as Bandana Dee. It does have a few supporters right at this moment unlike dying ones like Adeleine and Nightmare.
