Sequel
See Cartoon Network: The Robot War.

On April 6, 2019, Warner Bros. Interactive Entertainment has expressed interest in making a sequel, or perhaps, making a franchise out of it. Later, on April 20, 2019, just a day after the first DLC has been released, a Twitter post came up, saying that the sequel will have some big changes, which includes being able to not only play as Dexter, but Dee Dee too, the Eds and possibly Gumball and Darwin being original characters instead of DLC characters, and most importantly, a new villain. On June 11, 2019, a teaser trailer has been released, revealing the title, which is Cartoon Network: The Robot War.

Rumors say that it will include Time Squad, Codename: Kids Next Door, Hi Hi Puffy AmiYumi, The Face Paint'nimal Gang, The Marvelous Misadventures of Flapjack and ''OK K.O.! Let's Be Heroes'' as newcomers.

If it's true, then that would mean the sequel will have a lot more playable characters than in this game.

Trivia

 * Most of the voice recording for the video game was set in Los Angeles, save for the Ed, Edd 'n Eddy and The Amazing World of Gumball characters (set in Vancouver, British Columbia, Canada and London, England, United Kingdom, respectively).
 * Running Gag: In cutscenes, after the corrupted characters are defeated, Billy ends up saying "Fudgebutter!" only for a random building to collapse and injure Billy while the rest of the heroes run away before they get injured too.
 * Another Running Gag: When the Thing usually gets mentioned, everyone gets confused on what they are talking about.
 * In the main story's stages except The Thing's Dimension, there are various easter eggs hidden in them which have to do with shows that don't make an appearance in the main story and the DLC stories, for example...
 * In The City of Townsville, a broken radio can be seen playing a distorted theme song of Hi Hi Puffy AmiYumi.
 * In Genius Grove, there is graffiti on one of the damaged houses. One part of the graffiti resembles Robot Jones from Whatever Happened To... Robot Jones?
 * In The Desert, a damaged poster is seen near the desert which features Ciller the Centipede and Midder the Millipede from The Arachnid Friends, along with text that says, "WANTED: Two Creepy Crawlies."
 * In Endsville, the Sector V Treehouse from Codename: Kids Next Door could be seen. It could also be a reference to the crossover episode of The Grim Adventures of Billy and Mandy and Codename: Kids Next Door, The Grim Adventurea of the KND.
 * In the Land of Ooo, an action figure of Chowder from Chowder is hidden somewhere in Candy Kingdom.
 * In the Park, somewhere inside Pops' house, is a small painting of Captain K'nuckles from The Marvelous Misadventures of Flapjack.
 * In The Forest, one of the trees had a writing that says, "Ice Bear Was Here".
 * In Strangon, when you enter a damaged TV store, one of the TVs is showing Courage the Cowardly Dog screaming at the viewer.
 * It is theorized that the Thing is a pre-existing Cartoon Network character. However, it has later been debunked by Cartoon Network, claiming that it is an original character.
 * Before it was debunked, some fans claim the Thing is actually Alfe from The Problem Solverz, while others say it's Golly Gopher from Out of Jimmy's Head, yet others even say it's Dick Grayson/Robin from Teen Titans Go!.
 * One user jokingly claimed that it was a Nickelodeon character (notably someone like SpongeBob SquarePants, Timmy Turner, Ren and Stimpy, Lincoln Loud, etc.) who was trying to ruin Cartoon Network and make Nickelodeon a better kids' network than Cartoon Network.
 * Surprisingly, there was no claims of being one of the 2016 counterparts to the Powerpuff Girls, though it could be mainly due to them appearing in the game as their 1998 counterparts.
 * The same thing with the 2017 counterpart of Ben Tennyson, mainly due to him appearing as his 2005 counterpart in his Alien Force/Ultimate Alien age in the DLC.
 * Some fans thought the Thing was a demonic Cartoon Network villain such as Aku, Him, Nergal, etc in a different form.
 * This was eventually debunked after Aku being revealed as a DLC main antagonist.
