It seems that a game known as Nickelodeon All-Star Brawl has recently been listed for Nintendo Switch. This has generated speculation about a possible arrival of the title to the hybrid console.
As you know, this title has not been officially confirmed for Nintendo Switch. However, Gamefly has listed it with GameMill (Nickelodeon Kart Racers, etc.) as title holder for the October 5th of this year. By its name, it is speculated that it would be a fighting game with Nickelodeon characters.
The image that comes to mind is the one you have above, although unfortunately for now there are no official images of this premiere and it is only a fan-art inspired by Super Smash Bros. of SourceGaming.
We will be attentive to see if its release is finally confirmed on the Nintendo console. What is your opinion? Would you like to see it on Nintendo Switch?
