The Great Fox (グレートフォックス, Gurēto Fokkusu) is the mother ship belonging to the Star Fox mercenary group. The Great Fox appears in Sector Z, Corneria, and Venom. It also appears in the background of Lylat Cruise.
The Great Fox is a giant ship that has four large wings. In the front of the ship is a port that allows Arwings to enter and exit the ship. The front of the Great Fox has two turrets that fire high-powered energy blasts. The Great Fox serves as the base of operations for every one of Fox's team adventures since Star Fox 64, and it serves purposes ranging from launching and carrying the Arwings to having ROB 64 send Fox supplies.

 In Super Smash Bros.
The Great Fox appeared in Super Smash Bros. in the Star Fox 64 stage Sector Z, where the Great Fox acts as the platform on which the players fight each other. The players can only traverse the ship length-wise. The ship is greatly scaled down (or the fighters are greatly scaled up), as normally, the entire Star Fox crew can fit comfortably in the cockpit, and the ship can store several Arwings and other large vehicles. The ship also is shown very briefly in the game's intro, before the camera zooms into the bridge to show Fox.
In Super Smash Bros. Melee, the Great Fox is again reduced to a smaller, unrealistic size (however if the game mode is "Tiny Melee", all characters are smaller and are roughly to scale to the ship, though the Arwings and Wolfens are not). It is featured on two stages. In Corneria, the Great Fox acts as a platform as it did in Super Smash Bros., whereas the players traverse lengthwise, while in Venom, the player traverses the ship's width as it flies over the planet Venom from Star Fox 64. Its four wings become usable as platforms; the top two can be passed through. It again appears in the intro in Melee, shown along with the Captain Falcon's Blue Falcon and Samus Aran's Gunship.
In Super Smash Bros. Brawl, the Great Fox gives up its role as platform in the new Star Fox stage, Lylat Cruise, ceding it to the Pleiades. It still zips by in the background, however, and still appears in the Corneria stage, which returns from Melee. It is also featured in Adventure Mode: The Subspace Emissary.
 Subspace Emissary
The Great Fox briefly engages the Battleship Halberd in a quick battle over a giant wasteland. Shortly afterwards, it is defeated and carried off on the underside of the Halberd before being slammed into the Glacial Peak; however, what exactly became of the vessel after this remains unknown, as it is never seen after the "Snake's Mission Begins" cutscene, where it seen erratically fleeing the area, its engines heavily trailing smoke.
