Mario could not do it with Joker on the Mementos location from Persona 5
We already have confirmation that every challenger pack of the Fighters Pass for Super Smash Bros. Ultimate will provide a new character, a new stage, and accompanying music. None of the combatants are Echo Fighters.
It has been reiterated that the first DLC fighter outside of the Piranha Plant, Joker from Persona 5, will be released in April 201
Up until now, fans have only been able to speculate on which stage Joker will come with in Challenger Pack 1. While looking through the files of Super Smash Bros. Ultimate, DrHyperCake has claimed that he was able to find "Jack_Menentoes_" in a format that matches stage name strings.
Previous data miners have indicated that they believe that mentions or "Jack" in Super Smash Bros . Ultimate's code are references to Joker. Notably, there are also mentions to a "Brave" character that many are speculating about.
There is a possibility that the "Jack_Menentoes_" string found inside of the code is simply junk data but also a probably chance that Joker's inclusion internship is the Mementos location within Persona 5.
Like other internships within the game, it'll probably have a normal, Battlefield, and Omega variant. Of course, it's always a good practice to take any rumor or "leak" with a grain of salt until it's officially confirmed.
