Nickelodeon All Star Brawl (Streaker Prower and GabrielTheLoudTamer's Version)

Nickelodeon All-Star Brawl is a 2021 crossover fighting game developed by Sonic Team, Probe, Sora Ltd, and Bandai Namco Studios, and published by Sega. It is part of the Nickelodeon Super Brawl series of fighting games, serving as its fifth entry. Featuring characters from various Nickelodeon animated television series, the game was released on October 5, 2021, for Nintendo Switch, PlayStation 4, PlayStation 5, Windows, Xbox One, and Xbox Series X/S.

Gameplay
Nickelodeon All-Star Brawl is a platform fighter, with players battling on different stages and attempting to launch their opponents off the arena and out of bounds. Movement takes place on a two-dimensional plane, with characters able to move around by running, jumping, double-jumping, or performing a mid-air dash in any of eight directions. Characters have three different types of attacks: light attacks, which are weak but quick and can be used to perform combos; strong attacks, which are slower but do more damage and knock opponents back further; and special attacks, the properties of which vary by character. Different attacks can be performed by pushing up or down or running in combination with one of the three attack buttons. Players can also grab and throw opponents or enemy projectiles, even in the air, and guard against attacks without penalty, though they will be pushed back in doing so. Unique to the game is the "strafe" function, where players can hold a button to prevent their character from turning around while moving in different directions; this can be used to continue attacking an opponent while actively retreating from them. As characters take damage, the amount of knockback caused by opponents' attacks will increase, making them easier to knock off the stage. Each stage offers a different layout, with some also having additional hazards that can cause damage to the characters. During gameplay, a "Slime Meter" can be built up by attacking opponents and used in different ways, such as powering up attacks, extending aerial recovery, performing attack cancels, pushing opponents away, and activating powerful character-specific super attacks.

The game supports local and online multiplayer for up to four players, with the game's online functionality utilizing rollback netcode on supported platforms. The game also features a single-player roguelike campaign called "Dimensional Danger", in which players must stop Danny Phantom villain Vlad Plasmius from conquering the multiverse. Players start in the hub area, the "Timeless Stardial", where they can choose their character and interact with non-player characters to prepare for a run. When a run begins, players progress through nodes that each feature different challenges and special rules, including waves of enemies, platforming challenges, and boss battles. Players will receive free power-ups from non-player characters or purchase them using an orange blimp currency they earn during battle. These powerups will remain active for the remainder of the run; upon completion or defeat, the player's power-ups and blimps are discarded as they return to the Timeless Stardial. Players will also earn new playable characters by defeating them in battle, as well as green Slimy and purple Splat currencies, all of which are retained when a run concludes. Slimies can be spent on equippable perks that will grant the player additional benefits during a run, while Splat can be used to purchase additional slots for equipping perks, decorations for the Timeless Stardial, and upgrades for shops that expand their selection of purchasable items.

The game also features expanded arcade and training modes, new mini-games, and a boss rush mode. The game includes 26 stages, some of which feature selectable alternate layouts. In addition, support for cross-platform play has been added to the game's online multiplayer.
