What is the name of the Meta-Knights' airship?

The name of the Meta-Knights' airship is the Halberd. More precisely, it is Meta Knight's flagship and the centerpiece of his forces in Kirby Super Star's “Revenge of Meta Knight” mode.

Meta Knight launches the Halberd's invasion of Dream Land because he believes its inhabitants have become complacent and lazy. Kirby pursues the ship across several stages, eventually boarding it and fighting through its crew. The Halberd is armed with powerful technology, including the massive Combo Cannon, which makes it one of the Kirby series' most recognizable vehicles.

The Halberd is sometimes confused with other Kirby spacecraft. The Star is associated with Kirby, while the Lor Starcutter belongs to Magolor in Kirby's Return to Dream Land. The Egg is also not Meta Knight's ship. In later games, the Halberd is reused or redesigned, but its identity remains tied to Meta Knight.

Meta Knight himself is a recurring masked swordsman who often shifts between ally and rival. His signature weapon is Galaxia, while the Halberd serves as his mobile headquarters and battle platform.
