Maybe Zelda herself could be transported to the Avengers universe. With her wisdom and magic, she could assist the Avengers in different ways. She could use her magic to heal the wounded Avengers or help Tony Stark understand some ancient technology that has similarities to her own world's tech. She could also provide strategic advice based on her experience dealing with Ganon in her own realm.
One idea could be that the Avengers are somehow transported to the wizarding world. They might be initially confused by the magic but then start to work with the Hogwarts students and teachers to fight a common enemy, like a dark wizard who has also harnessed some sort of Muggle - like technology to become even more powerful. For example, Voldemort could team up with Hydra remnants to create a super - weapon that threatens both the magical and non - magical worlds.
A common theme is teamwork. Since it's a crossover, different characters from different universes or groups have to work together. For example, in an Avengers and X - Men crossover, they need to combine their powers and strategies.
One great 'pjo avengers crossover fanfiction' is 'The Demigod Avengers'. It has an exciting plot where the demigods from Percy Jackson and the Olympians join forces with the Avengers. The character interactions are really well - written, like when Percy uses his water powers in a fight alongside Thor's lightning.
One interesting aspect could be how Spider - Man's agility and street - level skills blend with the Avengers' more high - powered abilities. For example, his web - slinging could provide a unique form of transportation or capture for the team during a big battle against a powerful villain like Thanos. He could also use his spider - sense to detect threats that the other Avengers might miss.
In a fanfiction scenario, the Avengers might be on a mission to save Hannah Baker from the dark place she was in. They could use their different skills, like Captain America's leadership and Thor's strength, to help her overcome her internal demons. This could lead to an interesting story where Hannah becomes part of the Avengers' support team, using her own experiences to help them understand the importance of mental health.
A really interesting plot could be a time - traveling crossover. Supergirl goes back in time to the era of the original Avengers. She helps them in a battle that changes the course of history. In return, the Avengers help her find a way back to her own universe. During this time, she forms a special bond with Thor, as they both have superhuman strength and a connection to otherworldly powers.
It could be amazing. Picture Goku and Iron Man sharing their combat techniques. Goku might show Iron Man his ki blasts, while Iron Man could introduce Goku to his high - tech armors. They could team up against a common enemy like Thanos who has somehow acquired the power of the Dragon Balls. Their combined strength would make for an epic battle.
In the Legend of Chima and Avengers crossover fanfiction, imagine the Hulk in the land of Chima. His huge size and strength would be both an advantage and a source of confusion for the Chima characters. The Avengers, along with their new Chima allies, could face a threat that is causing chaos in both universes. Black Widow could use her stealth skills to gather information in the Chima jungles. Hawkeye might find the Chima bows and arrows very interesting and learn new archery techniques from the Chima warriors. It would be a story full of action, adventure, and unexpected alliances.
One possible plot could be that the Master Chief is somehow transported to the Avengers' universe. He teams up with Iron Man to stop a new threat that combines Covenant and Hydra technology. Their combined skills in combat and technology would make for an exciting adventure.
