Nicktoons: Legacy is an American action-adventure-comedy video game serving as a reboot to the Nicktoons Unite series. It is developed by High Voltage Software and published by Paramount Digital Entertainment through Nickelodeon Interactive Entertainment, being released for PC, Mac, PlayStation 4, Xbox One and Nintendo Switch on April 2nd, 2019. A Sega Orion port is currently in development with an unknown release with Iron Galaxy handling the port.
When Anti-Cosmo plans on using dimensional travel to achieve full conquest of the universe, SpongeBob leads a group of heroes to work together and stop him.
On what seemed to be a normal day at first, Timmy was seen watching TV when he spots a commercial about a new invention. Timmy, being somewhat interested, decides to keep watching it until it suddenly goes static. He then asks Cosmo and Wanda what is going on as the TV suddenly shows Anti-Cosmo. Anti-Cosmo then claims that he is going to take control of the universe as he laughs. Then, a portal appears with Goddard followed by Jimmy appearing out of it, which Jimmy tells him to enter the portal. Timmy is confused and asks what's happening. Jimmy claims he will explain later.
Later, in a huge lab, Jimmy explains that Anti-Cosmo has been planning on taking over the entire universe by travelling to different dimensions. Jimmy also revealed he sent several Nicktoon heroes to the lab so they can stop Anti-Cosmo, as those heroes show up, revealing themselves. Jimmy tells them that Anti-Cosmo has recruited several villains to attack areas.
The first area attacked is Retroville by Skulker and as he is attacking the city, he reveals that Anti-Cosmo has already begun his plan and Skulker himself is gonna stop the heroes from finding Anti-Cosmo. After defeating Skulker, they find a device that can open portals to get to areas faster.
