Nickelodeon All-Star Brawl is about as close as you're going to get to a Nickelodeon themed Smash Bros. game without actually being a Smash Bros. game. Unlike Smash Bros., which are only ever released on Nintendo platforms, Nickelodeon All-Star Brawl is coming to the PlayStation 4, PlayStation 5, Xbox One, Xbox Series X|S, and the Nintendo Switch in Fall 2021.
