What are some interesting ideas for Portal x Crossover Fanfiction?

One idea could be to cross X - 23 with the X - Men. Maybe she teams up with Wolverine to face a new and powerful enemy. They could use their similar powers in unique ways to combat threats.

Another interesting idea is a story where Mel teams up with some of the other test subjects she's only heard rumors about. They could work together to try and escape the facility in a more coordinated way than in the original game. In this fanfiction, there could be a lot of character development as they learn about each other's strengths and weaknesses.

You could do a crossover with the Inhumans. The X Men and Inhumans have some similarities in terms of having special abilities. In the fanfiction, there could be a misunderstanding at first between the two groups. For example, Beast could be fascinated by the Inhuman biology while some of the more hot - headed X Men like Gambit might be a bit more aggressive in their initial interactions. Then they would have to work together to face a threat like an alien invasion.

One idea could be that Tony Stark tries to modernize Dunder Mifflin's technology. He'd be frustrated by the old - fashioned ways of the office. Another could be Thor working as a temp at the office and constantly getting into comical misunderstandings because of his Asgardian ways. Maybe Hulk could be the office's security guard, scaring off any unwanted visitors in a very Hulk - like manner.

Another idea is a crossover with the Star Trek universe. The X - Men could find themselves on a Starfleet ship. They might have to deal with the differences in cultures and technologies while also trying to stop Apocalypse from spreading his chaos across the galaxy.

A genetic experiment gone wrong could also be a great plot for the crossover. A mad scientist tries to combine mutant and super - soldier DNA. This creates a new breed of dangerous creatures. The X - Men, with their knowledge of mutants, and the Avengers, with their combat skills and high - tech resources, must work together to contain the threat. Jean Grey's telepathic powers could be crucial in finding the source of the experiment, while Iron Man uses his technology to develop a way to reverse the genetic changes.

One popular 'portal crossover fanfiction' could be the one where the characters from Portal cross over into the Half - Life universe. In such stories, the unique portal - based mechanics add an interesting twist to the already complex Half - Life world.

One idea could be that Ichigo and Rukia find themselves in an alternate universe where their roles are reversed. Rukia could be the one with the Shinigami powers from the start in Karakura Town, and Ichigo is a normal human who gradually discovers his own latent spiritual abilities to help her. Another could be that they are sent on a special mission together to a realm neither has been to before, like a dimension full of lost souls. There, they have to rely on each other more than ever to find their way back and complete their task.

One idea could be that Naruto and Ichigo meet in a dimension where their powers are combined. They have to fight a new, powerful enemy that threatens both their worlds. For example, a villain who can manipulate the energy of chakra and reiatsu at the same time.

Perhaps there could be a plot where a villain in the bnha world discovers a way to summon demons from the kny world. This causes chaos as the demons start attacking the cities. The heroes and the Demon Slayer Corps then have to team up. The bnha characters use their quirks to support the kny characters in battles, like Bakugo using his explosions to create distractions while the kny characters go in for the kill.
