From the Super Mario Wiki
Final Destination is a stage that appears in every Super Smash Bros. game to date. It has absolutely no features, except for the large platform; so the combatants are not bothered by the stage in any way. In all four games, the Final Destination floats all around space, showing all the different landscape of the world. In the games, the places that the Final Destination travels through have changed.
Final Destination reappeared in Super Smash Bros. Melee as an unlockable stage, unlocked by clearing the Event Match "Showdown", and is still where the battle against Master Hand is held in Classic mode. The player may also battle Crazy Hand, if the right conditions are met. Final Destination is also where the player battles Giant Bowser in Adventure Mode. If the right conditions are met, the player is also be able to battle Giga Bowser afterwards.
In Super Smash Bros. Brawl, the stage is available from the start. Like in the past titles, it is a simple platform. In The Subspace Emissary, a Final Destination-like stage is the location of the final battle with Tabuu.
Final Destination returned in Super Smash Bros. for Nintendo 3DS / Wii U, with a different look. Like Super Smash Bros. Brawl, it features a background that takes place in space. It should also be noted that every stage has an alternate Final Destination incarnation. Also, in a new mode of online play, For Glory mode, these versions of the stages are the only stages available. Stages in their Final Destination form are stylized as Stage Name (Ω Form).
