Joker

Joker (whose real name is given as Ren Amamiya in some media) is the protagonist of ', a and  title from the ' franchise's spin-off  series. In his game of origin, he is a Japanese high school student in his day life; however, he also has the power to access an alternate version of the world called the Metaverse. In said universe, he infiltrates the psyche of corrupted souls to steal their hearts, and he can summon Personas, powerful demon-like creatures.

Super Smash Bros. Ultimate
During on December 6, 2018, it was revealed that Joker would be appearing as a paid downloadable playable character in Super Smash Bros. Ultimate. He is the second DLC fighter (with Piranha Plant being the first), and the first one in the Fighters Pass, releasing as part of "Challenger Pack 1". He was released on April 17, 2019 (PST), and is classified as fighter #71.

Aside from being able to wall jump, Joker has a special mechanic known as the "Rebellion Gauge", which is a meter that slowly fills up either over time, when taking damage or when Joker is behind his opponents in score/stocks, and fills up faster when he is attacked when using his down special, Rebel's Guard (as well as halving the damage taken). When this meter fills completely, Joker will summon the Persona Arsene, who assists him in battle by attacking in tandem with him, increasing the power and range of his standard moves. Joker's special moves are also enhanced, and his down special changes to Tetrakarn and Makarakarn. If Joker gets KO'd, the gauge will reset.

The player can choose to play as six color variations of Joker's Phantom Thief outfit wearing his mask, as well as two versions of his Shujin Academy uniform wearing his glasses. His victory screen mimics the one from Persona 5, with the color of the screen changing to match the current colors of the stage Mementos if Joker were to win on that stage. If Joker wins the match with his Final Smash, the splash screen that appears at the end of the move will carry over to the victory screen. He is one of the lighter middleweight fighters, being heavier than the Ice Climbers, Lucario, Wolf, and Villager, but lighter than Ness, Lucas, Mii Brawler, and Inkling.

Joker shares his English voice actor,, with the game's announcer, as well as Master Hand and Crazy Hand.

Classic Mode route
The route's title references Shadows, recurring enemies in the Persona series. The second, third, fourth, fifth, and sixth rounds each feature an opponent from the previous round as an ally; this could be a reference to Shadows being able to join the player's party as Personas in Persona 5.
