From WiKirby, your independent source of Kirby knowledge.
Necro Nebula is the fifth and final level in Kirby Mass Attack. It exists as its own world, guarded by a dark cloud which can only be penetrated by collecting every Rainbow Medal in the previous four levels. It consists of five stages, the first four of which are re-runs of all the previous bosses, and the last of which is the showdown with the final boss, Necrodeus.
Once this level is beaten, and Necrodeus defeated, the final cut-scene takes place, where the mini-Kirbys use the villain's staff to restore themselves to one full Kirby again. From there, the game's credits roll.
- This is the only level where Daroach's airship does not travel.
