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.

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.
