The Xevious universe (ゼビウス, Xevious) is a series of vertical shooters developed by Namco. In Xevious, the player controls a ship called the Solvalou, fighting against an alien army from the planet Xevious and their leader, a biocomputer known as GAMP.
The Xevious universe's first appearance in the Super Smash Bros. series is in Super Smash Bros. for Nintendo 3DS. It is one of the Namco franchises represented in the game, along with others such as Dig Dug, Galaxian, Mappy, Baraduke, Rally-X, and Pac-Man.
The Xevious universe in Super Smash Bros. Ultimate remained untouched from its previous appearance. Only Bacura was removed in the transition due to Smash Run not returning in this game.
