Toon Wars

Toon Wars is a currently ongoing fan-made series and expansions created by Frozarburst in 2017. It began as a series revolving around cartoons of different eras from both Nickelodeon and Cartoon Network fighting in a war with the evil Syndicate and other shows before it was given a sequel in 2020 with Toon Wars Legacy following various adventures after the war. Both games as well as anime were later adapted into universes of their own with Dragon Ball Ultra Army and Dust and the Sweeper and each piece of media went on to inspire the author in making his own original projects. Toon Wars along with all its expansions has its own wiki located here.

Toon Wars
The first series released in 2017 revolves strictly around Cartoon Network and Nicktoons teaming up against the Syndicate, who have started a war by manipulating various cartoons into fighting one another, as well as gathering different assets from the Nicktoons Unite series to plan a number of evil schemes, each worse than the last. The Nicktoons Saga took place roughly 10 years following the finale of Globs of Doom and reintroduced much of the characters from the game series (with the exception of Spongebob who wouldn't appear until The Final Days). A side story written around this time focused on the lesser known Mighty Magiswords cartoon, occurring immediately after Quest for Knowledge with the Warriors for Hire teaming up with some of their friends to stop an alien invasion. Toon Wars' second arc introduced the Nicktoons (who now go by the Toon Force) to the Cartoon Network universe in the form of Gumball Watterson fighting to save his town from a Syndicate invasion that led back to Volcano Island and the return of the Mawgu. Afterward, the series' third arc featured Samurai Jack after Season 5 of his cartoon being thrown along with some of the Toon Force into a darker version of Aku's timeline ran by him and the Syndicate as their penultimate goal, while the rest of the heroes were forced to fight the last of the rogue shows.

Several shorts, as well as side stories would be released in the gap between the Samurai Jack Saga and Toon Wars: The Final Days, including two miniseries bringing Magiswords into the series and multiple one-shot episodes detailing different adventures at various points in time, both comedic and others being more serious. But perhaps the largest, most impactful arc would be the series finale, The Final Days, following survivors of a virus outbreak in the Nicktoon/CN Multiverse trying to reach the center of reality to stop it. It featured the return of Spongebob Squarepants for what would be the original Unite crew's last adventure together and brought in several bits of lore that would go on to impact the sequel series and its expansions (i.e. the concept of Gods and the Fourth Wall itself).

Toon Wars Legacy and Its Many, MANY Expansions
In 2020, Frozarburst released a sequel set after The Final Days named Crossover Forces, which centered around a new Toon Force consisting of newer CN shows at the time such as Mao Mao fighting a new threat to the Toonverse in the form of Cyber Catra, a more insane duplicate of Catra from She-Ra: And the Princesses of Power. This, along with its two stories The Watterson and Dark Disney, widened the scope of the universe to the likes of Netflix, Disney, and numerous other media and inspired two more series set in the lore of Toon Wars. Dust and the Sweeper would be focused on video games, starting with Dust an Elysian Tail and Blinx the Time Sweeper, while Dragon Ball Ultra Army and its remake would be centered around anime.

Inspiration for Original Work
As mentioned WAY up top, the many fandoms seen in Toon Wars and its sequels heavily inspired much of the concepts being worked on for Anthroshock and Star Heart, which even includes concepts exclusive to Toon Wars itself. Several characters for Anthroshock especially were based on people from things like Danny Phantom, Little Tail Bronx, or Transformers to name a few, while Star Heart was more focused on comics and DC/Marvel films/cartoons. One key thing to note about Frozarburst's art style especially is that much of it can be traced back to things such as Justice League Unlimited, Mighty Magsiwords, or OK K.O. Let's be Heroes, hence its versatility. Even more important is that certain characters for Anthroshock during development were previously written as fanon characters before they were moved. Those like Levi, Fusion, Aegis, and Trio essentially were given an introduction through fanfiction and completely rewritten for original content.

Trivia

 * All rights to each property in Toon Wars are owned by their respective owners...obviously. You'd think I wouldn't have to say that, but y'know how sensitive copyright bots are.
 * Even though Toon Wars was released in 2017, the first arc of the series was posted AFTER Mighty Magiswords: Fusion Wars. And development for the series dates as far back as 2007 when the Nicktoons Unite games were still going. A lot of ideas from then, especially in the 2015-2016 version were either dropped or completely revamped into what we'd eventually get in the final release, such as reboots being used as the main antagonists being rejected entirely to stay unbiased or Spongebob not being used until the last arc to give focus on least expected shows like Magiswords or Gumball.
