 * 3 main characters from PB&J Otter, will have new dialogue, due to the original their voice actors, sounding too old to voice them.
 * Jelly Otter will be voiced by Anndi McAfee, as her original voice actress "Jenell Brook Slack", sounded too old to voice her.
 * Also as well for Peanut, and Baby Butter are going to be voiced by Vanessa Marshall, and Grey DeLisle-Griffin, respectivly.
 * Pit's voice actress, was originally going to be Lani Minella, but later replaced by Antony Del Rio, due to the release of Kid Icarus: Uprising, which was released on March 23, 2012. As Lani can voice other characters in the game.
 * Mike's new voice actor will be Christopher Sabat (who is known for characters in English dubs of anime), after his original voice actor Rod Roddy (who voiced him in House of Mouse), passed away in 2003.
 * Gumball and Darwin's voices will have new dialogue, and archival audio from past seasons, of The Amazing World of Gumball, due to their recent voice actors hitting puberty. Nicolas Cantu, and Donielle T. Hansley Jr. will assume their roles in the game.
 * Lincoln's voice as well, will also have new dialogue, and archival audio from the first season, and pilot, due to his previous voice actors hitting puberty, Collin Dean will assume his role in the game.
 * This was originally going be the first fighting game to be published by Disney Interactive Studios, but changed to Warner Bros. Interactive Entertainment, due to the closure of Disney Interactive Studios in 2016. The same company that distrbuted some Cartoon Network video games.
 * Originally, Luan was going to be a non-playable character, but changed to playable, due to the updated version of Super Brawl World from Nick.com, adding her, and Cylde.
 * This game will be similar to Mugen, another fighting game, where they feature crossovers.
 * It also will be similar and have elements from Lego Dimensions, another crossover videogame.
 * Originally Captain Falcon, Snake, Ezio and Sonic the Hedgehog would not appear. But due to the recent launch of the new Super Smash Bros. for Wii U/3DS game, they're written to be added.
 * This will be the second Cartoon Network fighting game, the first was Cartoon Network: Punch Time Explosion.
 * This will be the second Hitler Parody Fighting Games the first was Bunker Kombat.
 * The game was originally going to be on the Wii, and later Wii U, but changed to Nintendo Switch, due to Wii U having ended production, new upgrades, and eighth-generation of video game consoles.
 * This is the 2nd game, in which Hynden Walch voices Princess Bubblegum, and Starfire (from Adventure Time, and Teen Titans Go! respectively), other then just Viridi from Kid Icarus series. The first being Super Smash Bros. from 3DS/Wii U, and the second is Lego Dimensions.
 * Lance won't voice SML Shrek in the game, due to duplicating with the character from the movie of the same name..

International/Reigonal version differences

 * In the Japanese version, some Nickelodeon characters (like from The Loud House), and Family Guy characters won't appear, due to some Nickelodeon shows (like Welcome to the Wayne), and the adult comedy, which hasn't aired in Japan.
 * Chuck E. Cheese characters won't appear in the European, Korean, and Japanese versions, there no being no locations around Europe, and Asia. As Chuck E. Cheese's does not make international versions of acts, or dub the characters in other languages (although "Rockstar Birthday" was also released in Spanish, and for locations in South America, and the Middle East, but they're left in English).
 * SuperMarioLogan characters will be exclusively in the North American, Australian, and Europe (UK) versions only. Because the web series was never released in other languages, than English (although some characters speak Spanish in the series), similar to how Frank West spoke in English but his quotes are subtitled in Tatsunoko vs. Capcom.
