Nickelodeon Superstar Brawl

Nickelodeon Superstar Brawl is a platform fighting game where various Nickelodeon characters crossover. It is a spiritual successor to Nickelodeon All-Star Brawl.

Gameplay
As a Platform fighter, players move around on a stage with varied layouts; with the main objective to knock their opponents off of it. Like its predecessor; characters have a light attack; which are weak but can be used to make combos, Strong attacks; which are slow but powerful, and special moves; which are tied to the characters themselves. Unique to this version is a Ultimate move called "Slime Buster". A Slime Buster is a powerful move that can be obtained by hitting the powerful Slime Orb, which enables the characters to use their powerful move. If enabled, players also has a gauge meter for their Slime Buster as well, which gets filled up if the character gets attacked.

Characters
The game improves on All-Star Brawl's roster by adding over 70+ characters. This also resolves issues with representations of several series. Leonardo and Michelangelo return but they're also group together alongside newcomers; Raphael and Donatello. As such, they are counted as one character.
