Dark Nebula (Dark Zero in the original Japanese version) is a fictional character in the Kirby series of video games. It is the final boss of Kirby: Squeak Squad, and the true villain of the game. He commonly appears as a giant black star with a purple glow/flames around his body and a red/pink/purple cat-like eye in the center. Some fans believe it to be the same entity as 0 from previous Kirby games, due to his Japanese name.

Dark Nebula was locked away in a treasure chest found in King Dedede's castle. After Kirby beats King Dedede at the end of Prism Plains, the Squeaks attack and take the treasure, which they think is the one that contains an ultimate power. What they don't know, however, is that the chest really contains the sinister Dark Nebula inside it. After Kirby beats Daroach at the end of Island Ice, Meta Knight appears out of nowhere and takes the chest and escapes with it to the Halberd at the bottom of the Secret Sea, which Kirby will need five colored stars to access through that door that MK has escaped through. After he beats MK to reclaim the treasure, Daroach takes it again and opens it only to become possessed by Dark Nebula and then known as Dark Daroach. After Kirby defeats Dark Daroach at the end of the Gamble Galaxy, Dark Nebula leaves his body, reverting him back to normal Daroach and his colors back to normal. Afterwards, Kirby gets the Triple Star and is able to chase Dark Nebula through two short areas before battling it.
