One great example could be a story where Jack Frost from Rotg teams up with the Avengers. Maybe he uses his ice powers to help them in a battle against a common enemy like Loki who has somehow gained control over a powerful ice - related artifact. Jack could freeze Loki's magic for a short time, giving the Avengers an advantage.
One great example could be a story where Flash uses his super speed to help the Avengers in a battle against a time - traveling villain. Maybe he's able to disrupt the villain's time - based powers, giving the Avengers an edge. Another could be a fanfiction where Flash has to adapt to the Avengers' more teamwork - oriented style of fighting, which is different from his solo adventures in his own universe.
One great example could be a story where Batman's detective skills are put to the test in an Avengers - style global threat situation. Maybe he teams up with Iron Man to analyze some high - tech alien weaponry. Another could involve Nightwing and Hawkeye having an archery - based competition that turns into a team - up against a group of villains. And there's also the idea of Alfred and Jarvis having a conversation about taking care of their respective heroes, which could be both humorous and heartwarming.
One great example could be a story where Buffy Summers finds herself in the Avengers' world. Maybe she teams up with Black Widow, sharing their combat skills and female empowerment stories. Another could involve the Avengers having to deal with a vampire threat that only Buffy has the expertise to handle.
There's a fanfiction where Storm's weather - controlling abilities are crucial in an Avengers - level threat. The X - Men and Avengers have to work together to stop a global weather - based disaster. In some crossovers, Cyclops' optic blasts are combined with Hawkeye's archery skills in a strategic way. They create a unique combat style that helps the combined team take on enemies. Also, Rogue's power - absorbing ability can lead to some really interesting interactions when she absorbs the powers of various Avengers members.
Well, for instance, Captain America's leadership skills could be combined with North's knowledge of different realms. North could lead the Avengers into his world if they needed to hide or strategize in a different environment, and Cap could keep everyone in line and focused on the mission.
One popular rotg crossover fanfiction might be the one where the characters from ROTG cross over into a modern-day city setting. It adds an interesting twist as they interact with the normal humans and face new challenges.
One great example could be a fanfiction where the Avengers come together to help a small, war - torn village not for glory but out of pure good intent. They use their powers to rebuild the village, teach the children, and bring peace. It shows a different side of the heroes, focusing on their selfless motives.
One great example could be a fanfiction where Falcon takes on a leadership role in the Avengers. Maybe after some initial doubts from the team, he proves his worth by devising a brilliant strategy to defeat a new enemy. This could show his growth from being a sidekick - like figure to a true leader within the Avengers.
Well, a story where there is a mix - up of powers could be fascinating. What if the members of Team 7 got some of the Avengers' powers and vice versa? Naruto with the ability to fly like Iron Man or Hulk with the ability to use shadow clones. This would change the dynamics of both groups and create a whole new set of challenges and adventures for them.
In a rotg and httyd crossover fanfiction, perhaps the Guardians could come to Berk to protect it from a new threat. Pitch Black might team up with some dragon hunters, and the httyd characters along with the Guardians would have to work together. Hiccup could learn some new skills from the Guardians, like how to be more stealthy from Jack Frost, and the Guardians could be in awe of the dragons' intelligence and strength.
