OK KO, Let's Be Heroes! is a Cartoon Network series (2017-2019) set in a future world where there are many superheroes. K.O. is a young boy who hangs out at Lakewood Plaza where his mother works, interacting with other employees and honing his superhero powers. Sounds like a lot of noisy battles. But apparently six characters end up in same-sex relationships:
Enid, a teenager training to be a ninja, and Red Action, a cyborg teenager from the future (even farther in the future).
Main villain Lord Boxman, a corporate bigwig obsessed with destroying Lakewood Plaza and the even more evil Professor Venomous
The trio escapes from the lava and gets even with Boxman by pretending to be chefs. They sabotage the dinner with slapstick routines, including sneezing pepper and pies in the face.
