Mementos

Mementos is a downloadable stage that appears in Super Smash Bros. Ultimate, and is based on the recurring location of the same name in . It was released alongside Joker on April 17, 2019.

The stage consists of a main platform with a small slope in the middle and two Semi-Solid Platforms. After a while two trains appear on the top and bottom of the stage, with the bottom train being able to damage fighters. Occasionally, a wall or ceiling will appear temporarily on the top or the sides of the stage, which fighters cannot pass through. The Morgana Bus occasionally rides in the background of the stage and will disappear through a portal, but it does not affect the fighters.

While the default color scheme is red, based on Persona 5's main color scheme, when a music track from ' or ' is selected to play on the stage, its color scheme will change to blue or yellow, respectively. This change also applies to Joker's victory screen if he wins on the stage.
