One popular idea is an Erza crossover with the Harry Potter universe. Imagine Erza attending Hogwarts and using her combat skills in magical duels. Another is a crossover with the Avatar: The Last Airbender world. Erza could learn bending techniques and fight alongside the Avatar. A third could be a crossover with the Naruto universe, where she might interact with ninja and use her magic in the shinobi world.
Another plot could involve a crossover with the Harry Potter world. Erza could be a transfer student to Hogwarts. Her magic, which is different from the wizarding magic, would create a stir. She might have to face off against Voldemort's forces while also learning about the magical world of wands and spells.
A cool plot could be that there's a magical artifact that has the power to grant any wish. Ichigo and Erza both hear about it independently and end up chasing it. When they meet, they initially think the other is an enemy. But as they start to understand each other's motives, they decide to share the wish if they get the artifact. However, they face many challenges along the way, like traps set by other people who also want the artifact. Erza's strategic mind and Ichigo's determination would be great assets in this adventure.
Some people like the idea of a Slenderman and Minecraft crossover in fanfiction. Picture Slenderman lurking in the blocky Minecraft landscapes, scaring the players. Another possible crossover is with the Gravity Falls universe. Dipper and Mabel could stumble upon Slenderman during one of their adventures in the strange town. And a crossover with the Resident Evil series would be intense. Slenderman in a world full of zombies and bio - horror threats would create a really complex and terrifying scenario for a fanfiction.

A cool crossover would be with the One Piece universe. Rin could be on a pirate ship, using his powers during sea battles and exploring the Grand Line. Another idea is a crossover with the My Hero Academia world. He could attend U.A. High and learn about different quirks while also showing off his own unique abilities. A crossover with the Inuyasha world would also be great. He and Inuyasha could team up to fight demons together.
Another popular crossover is with the Pokémon world. Samus exploring the Pokémon regions, perhaps using her skills to help or hinder trainers. She could encounter powerful Pokémon and have to use her own abilities to get out of tricky situations. It's an interesting contrast between her high - tech world and the more natural, creature - based world of Pokémon.
