How could a Voltron and Steven Universe crossover work in fanfiction?

A really interesting plot could be that a powerful Gem weapon is stolen and ends up in the Voltron universe. The Paladins find it and don't understand its power at first. Meanwhile, the Crystal Gems think the Paladins are the ones who stole it on purpose. So there's this initial conflict. But as they start to communicate, they realize there's a bigger threat behind the theft. A shadowy figure is trying to use the weapon to destroy both universes. So they must join forces to stop this threat. The story could explore how the different characters interact and grow to trust each other.

Well, it could work by having the different power systems interact. For instance, the chakra in Naruto's world and the gem magic in Steven Universe. The Juubi's power is so immense that it could disrupt the balance in the Steven Universe. Naruto, being a powerful ninja, could teach the characters in Steven Universe about combat techniques that are different from their own. And the gems could introduce Naruto and his friends to new forms of energy manipulation.

It could be really interesting. Maybe the gems from Steven Universe end up in the spooky world of FNAF. They could use their powers to fight off the animatronics. For example, Garnet's strength could be used to hold the animatronics back while Pearl uses her spear to disable them.

Well, in such a crossover, Steven could use his gem powers to help the Avengers in battles. Maybe his healing powers could be used on the injured Avengers. For example, after a tough fight with a powerful villain like Thanos, Steven could heal Captain America's wounds.

It could be really cool. Imagine Steven's gem powers interacting with the Transformers' technology. Maybe the Crystal Gems could help the Autobots in some way, like using their powers to repair damaged parts. Or the Transformers could introduce new ways of using energy to the Gems.

A Markiplier and Steven Universe crossover fanfiction could be really interesting. Maybe Markiplier's character could end up in the world of Steven Universe. He could interact with the Crystal Gems, and his comedic and often chaotic personality would create some really fun and unexpected situations. For example, he might try to help Steven with his gem powers in a very unorthodox way that would make everyone laugh.

Well, it could be really wild. Maybe Steven could use his gem powers to try and stop Zim's crazy plans for world domination. Zim, on the other hand, would probably be super confused by Steven's powers and the whole concept of gems.

If it was a crossover with "She - Ra and the Princesses of Power", Adora could be a main character. Her strong leadership and the power of She - Ra would be an interesting contrast to Steven's more laid - back leadership style. Together, they could fight against a common enemy that threatens both their worlds.

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.

To write a good Steven Universe FNAF crossover fanfiction, you need to consider the tone. Since Steven Universe is more light - hearted in general and FNAF is horror - based, find a balance. You could start with the Steven Universe characters in their normal setting and then gradually introduce the FNAF elements. Let the characters react realistically to the new and scary situation. For instance, Amethyst might initially be curious about the animatronics but then get scared when they start acting strangely.
