Nickelodeon All-Star Brawl's release date was accidentally revealed by Nintendo this week, and now a similar listing has revealed four more of its fighters.

Nickelodeon's answer to Super Smash Bros. was announced earlier this year in the form of All-Star Brawl. A fighting game that will allow players to pick characters from some of their favorite Nicktoons and pit them against one another. Reptar versus SpongeBob and Danny Phantom versus CatDog are just a couple of the dream matches you will be able to play a part in.

Nintendo accidentally revealed earlier this week that the wait for All-Star Brawl isn't a long one. According to its eShop listing, the game will be here on October 5. Now Nintendo appears to have also leaked a few of the game's unannounced fighters. Artwork, which was also discovered on All-Star Brawl's eShop page, shows four fighters yet to be officially announced.

As is the case whenever the build to a new Smash fighter announcement, people have been debating who else might join All-Star Brawl. Characters from Avatar have been very popular choices, making this leak from Nintendo a welcome one. The artwork shows both Aang and Korra just over SpongeBob's shoulder, with two more unannounced fighters right above his head.

Those other two are Ren and Stimpy, who many would have assumed were going to be a part of the game anyway. The duo are two of the most famous Nickelodeon characters of all time. What isn't clear is whether the two of them will work as a team like the Ice Climbers. All four new characters will presumably get official announcements in due time, just like CatDog and April O'Neil did at Gamescom.

If the Nintendo leak is accurate, then All-Star Brawl will launch on October 5, presumably on all of the platforms it has been announced for. It also seems as if, like Smash, its fighters will be revealed and maybe even added over time. Even though Aang, Korra, Ren, and Stimpy will be announced at some point, that doesn't necessarily mean they will be available at launch.
