Nickelodeon All-Star Brawl 2 is a 2023 crossover fighting game developed by Fair Play Labs and published by GameMill Entertainment.

[2][3] A new single-player roguelike campaign has been added, in which players must stop Danny Phantom villain Vlad Plasmius from conquering the multiverse.

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.

Vlad, who is now trapped there as well, cryptically reveals that the heroes made a mistake in stopping him, and Master Splinter hypothesizes that Clockwork may have had ulterior intentions for refusing to return the displaced characters to their original worlds.

In June 2023, prior to its announcement, several images from Nickelodeon All-Star Brawl 2, including development screenshots and partial box art, were anonymously leaked online.

[22] Nickelodeon All-Star Brawl 2 marked the debut of Jacqueline Grace Lopez as Korra, following Janet Varney's departure from the role.

Per her behalf, Varney insisted a woman of color should take over the role, as her final time voicing the character was in Nickelodeon Kart Racers 3: Slime Speedway the previous year.
