What are some interesting Ken Kaneki crossover fanfiction ideas?

One idea could be a crossover with the world of 'Fullmetal Alchemist'. Kaneki Ken could be a chimera created by some dark alchemical experiment. His kagune could be seen as a strange alchemical creation. Another could be a crossover with 'Attack on Titan', where Kaneki joins the Survey Corps and uses his kagune to fight Titans in a unique way.

One idea could be a crossover with the 'Harry Potter' universe. Ken Kaneki could be a new student at Hogwarts, dealing with his ghoul powers while also learning magic. Another could be a crossover with 'Attack on Titan', where he helps the Scouts fight Titans, using his unique abilities. Or perhaps a crossover with 'My Hero Academia', where he attends UA and has to navigate the world of heroes and villains.

One plot idea could be that Ken Kaneki somehow gets transported to the world of 'Fairy Tail'. He might initially be seen as a threat due to his ghoul nature, but as the story progresses, he could form alliances with the Fairy Tail guild members. Maybe he helps them fight against a common enemy that has some similarities to the ghoul - like threats in his own world.

One idea could be an evil Kaneki crossover with the world of 'Attack on Titan'. Kaneki's unique kagune abilities could be a new form of weapon against the Titans. He might start off as an experiment by the Marleyans similar to how he was experimented on in the original Tokyo Ghoul story. Another idea is a crossover with 'Fullmetal Alchemist'. Here, Kaneki's struggle with his inner ghoul side could be paralleled with the Elric brothers' search for the Philosopher's Stone to regain their bodies. He could be seen as a new type of chimera in this world.

One idea could be to have Kaneki enter a parallel universe where he has to team up with a powerful centipede - like being to fight a common enemy. Maybe they are both trying to stop an evil organization that is experimenting on ghouls and creating mutant centipedes.

One interesting story could be about Kaneki Ken's unique abilities being introduced into the RWBY world and how he teams up with Team RWBY. Maybe his kagune could be a new form of combat power that the RWBY characters have never seen before.

Tatsumi from 'Akame ga Kill!' would be a great pair. Tatsumi is a fighter who has a strong sense of justice, and his interaction with Kaneki, who has his own moral struggles as a ghoul, could create an interesting dynamic. They could fight together against common enemies in a crossover world.
