Dragoon

The Dragoon is a legendary air ride machine from Kirby's Air Ride, appearing in Super Smash Bros. Brawl. Broken into three parts, the player has to collect Dragoon Part A, the nosecone, Dragoon Part B, the hull, and Dragoon Part C, the tail. Each player can collect one of the three parts of the ship, but only when one player has all three of the same time, they can use it to crash into the stage, knocking out all players who are hit by the Dragoon. When a player is hit or knocked out, he or she loses the parts of the Dragoon he or she has already collected, allowing other players to take the parts of Dragoon.

It should be noted that the Dragoon parts don't always appear in every single match, nor do the parts appear in certain stages.

Role in Subspace Emissary
In the Subspace Emissary, the air machine appears once and acts similar to the Warp Star (as Kirby's vehicle). In the scene when Ganondorf and Bowser just blew up the Halberd, after the explosion happens, almost all of the heroes of the game arrive in their ships (Fox is in his Arwing, Samus is in her ship, Captain Olimar is in his ship and everyone else is in Captain Falcon's ship) They all continue shooting the enemy ship and the enemy's ship also fires back. However, the enemy's ship is so large that the aircrafts don't do much damage to the large ship. Just when it seems the heroes are losing, Kirby comes flying in on Dragoon and flies straight at the ship's cannon. He flies through it, destroying the cannon in an explosion. The other ships then keep firing at the ship and soon, the whole ship is on flames. However Ganondorf and Bowser escape in a strange type of "Warp Door" and leave right before the whole ship explodes.

Trivia

 * In the game Kirby's Air Ride the Dragoon is used more for gliding than attacking. In Super Smash Bros. Brawl, it is used offensively like the Hydra, another Air Ride Machine in the same game unlocked in the same way.
