The crossovers just keep on coming in Ubisoft’s money-making free-to-play Smash Bros. fighting game clone Brawlhalla.

Ubisoft announced that it’s teaming up with Nickelodeon to add in characters from Avatar: The Last Airbender. The heroes are Aang the Airbender, Toph the Earthbender, and Zuko the son of Fire Lord Ozai and master Firebender.

The launch also kicks off the latest Crossover Event, featuring Western Air Temple-inspired maps for free-for-all and 1v1 matches, Momo emote, Cabbage Merchant KO effect, Appa sidekick, and new themed emojis and avatars. Players who log in during the event will also earn ”The Tale of Iroh” profile avatar for free. All items will still be purchasable and playable, and the maps will still be playable, after the event ends.

This means that the trio will be joining Leonardo, Raphael, Michelangelo, and Donatello as the only Nickelodeon characters to join Brawlhalla’s roster as guest characters so far. Check out the crossover trailer below.
