The mod is currently in beta, and was on hiatus for a while, but Sleepy Jirachi is back and working on it once again. Using the models of the Pokémon already present inside Brawl from the Poké Balls you throw to summon support, Sleepy Jirachi adds custom movesets and animations to each Pokémon so that they have the feel of being unique fighters that remain faithful to the original characters. What you can see in the video is a fight between Ganondorf, Blaziken, Mewtwo, and Electivire. As the title of the mod implies, it adds a bunch of extra playable Pokémon fighters to the game’s roster. YouTube user Sleepy Jirachi has uploaded a video of their upcoming “Pokebrawl” mod for Super Smash Bros.
