The Battleship Halberd is Meta Knight's warship, first starring in Revenge of Meta Knight, built to help Meta Knight take over Dream Land. In the later games, it usually makes important appearances but ends up getting destroyed in most cases. It's power source is the reactor, which is powered by Wheelies, but the conversation between the Meta-Knights indicates that it may rely on solar energy as well.
AppearanceEditThe Battleship Halberd's appearence varies from game to game. Still, it kept Meta Knight's mask, it's elongated bow, it's bat-like wings and tons of cannons throughout the series. It is about as large as Castle Dedede.
