What could be an interesting plot for a Steven Universe and OK KO crossover fanfiction?

Perhaps OK KO travels to Steven's universe and is amazed by the different types of gems and their abilities. He could learn from Steven about gem culture and in return, teach Steven some of his cool fighting moves. This could lead to them going on an adventure together to help a group of gems who are in trouble.

Maybe a corrupted gem that has the ability to control technology. It sees the world of OK KO as a perfect place to spread its corruption. It takes overobox robots and uses them to attack both the heroes of OK KO and Steven. This gem villain could be really powerful as it combines the strength of gems and the technology of theobox world.

Enid from OK KO and Pearl from Steven Universe. Enid is a bit of a cool, laid - back character with her own brand of strength, and Pearl is a very refined and skilled gem. They could have a great dynamic, like Enid teaching Pearl some modern - day Earth things, and Pearl showing Enid some of her elegant combat moves.

A crossover with Adventure Time would also be cool. Ok Ko could end up in the Land of Ooo. He might team up with Finn and Jake to battle some sort of evil force that threatens both the plaza and Ooo. They could exchange their different fighting styles, like Ok Ko's formal karate training compared to Finn's more improvised sword - fighting.

One possible plot could be that Steven and the Crystal Gems end up in Gravity Falls. They could team up with Dipper and Mabel to solve a mystery that involves both the magic of Gravity Falls and the Gem technology. Maybe there's a Gem hidden in Gravity Falls that has been causing strange phenomena, and together they have to find and deal with it.

A plot could involve a powerful villain that threatens both the Naruto universe and the Steven Universe. So, Naruto and Steven have to team up. Steven could use his healing powers on Naruto's friends who get injured in battles, and Naruto could use his Rasengan to break through tough defenses of the enemy. They could also exchange their beliefs and values. Naruto could teach Steven about perseverance and never giving up, while Steven could show Naruto the power of love and acceptance in a more in - depth way.

The mash - up of different settings. The Ok Ko world with its own set of rules and the Nexus world which is likely very different. When combined, it creates a really unique backdrop for stories.

One idea could be a crossover with another popular animated show like 'Steven Universe'. OK KO could end up in Beach City and have to team up with Steven to fight off a new type of gem - infected villains. They'd combine their unique powers, like OK KO's power fist and Steven's shield, to take on the bad guys.

One possible plot could be that the Gems come to Gravity Falls to investigate some strange energy readings that are similar to their own gem powers. They meet Dipper and Mabel, and together they figure out that there is a connection between the two worlds' magic.

In some fanfictions, OK KO could go on a journey to a different dimension. This would be full of strange creatures and new challenges. He'd have to use his wits and powers in unique ways to find his way back home while also helping the inhabitants of that dimension.
