Well, in a Goku and Marvel crossover fanfiction, the story could start with Goku somehow ending up in the Marvel universe. He might initially be confused but quickly adapt. He could get involved in the conflicts of the Marvel world, such as the ongoing battles between the X - Men and the Brotherhood of Mutants. His pure - hearted nature might influence some of the more morally ambiguous characters in Marvel. And his training - obsessed attitude could inspire characters like Spider - Man to train harder and reach new levels of power.
Well, it could be about Supergirl getting accidentally transported to the Marvel universe. She might team up with Captain Marvel. They could fight a common enemy like Thanos who has somehow gotten his hands on Kryptonian technology. It would be a clash of two very different power sets and universes.
It could be amazing. Maybe Percy and his demigod friends team up with the Avengers. Percy could use his water powers to help against a fire - based villain like Hela. His sword fighting skills would be useful in close combat with the likes of Loki. The demigods' magic and the superheroes' powers would create really interesting battle scenes.
The plot could involve a threat that requires the combined efforts of both universes. Maybe an ancient evil that can only be defeated by the unique powers of Naruto characters and the technology and superpowers of Marvel heroes. For instance, a villain who can absorb all forms of energy is threatening both the ninja world and the Marvel universe. Naruto and his friends team up with the Avengers to stop this threat. Along the way, they have to learn to work together, which could lead to some interesting character interactions, like Naruto trying to understand Stark's high - tech gadgets or Thor explaining his Asgardian magic to the ninja.
In this fanfiction, Master Chief could bring his military discipline and strategic thinking to the Marvel Universe. He might find himself in the middle of a conflict between different superhero groups. His no - nonsense attitude could either cause friction or inspire the heroes to work more efficiently together. There could also be a sub - plot about him trying to find a way back to his own universe while still helping out in the Marvel one.
In this crossover fanfiction, the Marvel heroes could visit the world of 'Phineas and Ferb'. Spider - Man would be swinging around Danville, impressing the local kids. The Phineas and Ferb gang could show the Marvel heroes how they build those huge and elaborate projects in just one day. And there could be a plot where Doctor Doom tries to steal the boys' inventions to take over the world, and the combined forces of 'Phineas and Ferb' and the Marvel heroes have to stop him.
The characters could interact in many ways. Goku could have a friendly sparring match with Captain America. Cap would be impressed by Goku's power and fighting skills, and Goku would respect Cap's leadership and unwavering will. Or Goku could help Iron Man upgrade his suit with some of his Saiyan technology knowledge.
It would be chaos! Goku's insane powers would throw the balance of power in the Marvel universe completely out of whack.
It would be amazing. Picture Goku teaming up with Iron Man. Goku's raw power combined with Iron Man's high - tech gadgets could make for some epic battles against villains like Thanos or Frieza. They could learn from each other's fighting styles too. Goku might be intrigued by Stark's intelligence and technology, while Iron Man could be in awe of Goku's ability to constantly increase his power level.
Well, perhaps Harley Quinn is kidnapped by a Marvel villain who wants to use her unique skills for his own evil plans. Let's say it's Loki. He brings her to the Marvel universe. Harley, of course, doesn't take kindly to being used. So she escapes and teams up with the Guardians of the Galaxy. They travel across different planets in the Marvel cosmos to stop Loki's master plan. Along the journey, Harley has to adapt to the strange new world of the Guardians, and there are lots of funny exchanges as she tries to understand their ways and they try to understand her.
Well, it could be about Saitama getting teleported into the Marvel universe. Maybe he'd start by accidentally punching a low - level villain really hard and causing a huge commotion. The Avengers might initially see him as a threat, but then realize he's just a super - strong, bald hero who just wants to fight strong opponents. He could team up with them to take on Thanos or some other big baddie.
