A cool plot could be that a time - traveling device from the Mission: Impossible universe gets into the wrong hands in the Avengers world. This device is being used to rewrite history in a way that benefits a powerful and evil entity. The Avengers, being no strangers to time - travel shenanigans, team up with Ethan Hunt and his crew who are experts in retrieving and securing dangerous items. They embark on a wild adventure across different timelines to stop the device from being misused.
Well, perhaps the Avengers are framed for a series of impossible - seeming crimes around the world. Mission: Impossible team is tasked to hunt them down. But as they start to investigate, they realize that there is a bigger conspiracy at play. A shadowy organization is trying to start a war between the Avengers and the world governments. So, the two teams end up working together to expose the real villains and clear the Avengers' names.
One possible plot could be that Ethan Hunt's IMF team discovers a global threat that is related to some alien technology left over from an Avengers battle. They then seek the help of the Avengers. The Avengers, on the other hand, are dealing with political issues regarding their superhero status and see this as a chance to prove their worth again. Together, they combine their skills, like Iron Man's tech with Hunt's spy gadgets, to take on the new threat.
Maybe the Avengers lose some crucial technology due to a heist, and they suspect it's the work of an international syndicate. The Mission Impossible team gets involved as they are experts in dealing with such groups. The two teams then have to combine their skills. Iron Man could work with the tech - savvy members of the Mission Impossible team to track down the technology, while Captain America and Ethan Hunt lead the strategic planning.
They'd probably be intrigued at first. The Avengers are used to big - scale battles, but Mission Impossible - style missions with their focus on stealth and intricate planning would be a new concept. Thor might find it a bit strange as he's more into direct combat, but Iron Man would be interested in the high - tech gadgets used. Captain America would respect the discipline and planning involved.
That would be an amazing crossover! Ethan Hunt's skills in espionage, acrobatics and combat would be a great addition to the Avengers. He could use his stealth to gather intelligence and his physical abilities to take on enemies in close - quarter combat. Maybe he could teach Black Widow some new spy tricks or go on a mission with Captain America.
Iron Man and Ethan Hunt would be an amazing pairing. Iron Man with his high - tech suit and Hunt with his resourcefulness. They could share their knowledge of gadgets and come up with some really cool strategies to defeat the enemy. Another great pairing could be Black Widow and Ilsa Faust. Both are strong female characters with great combat skills and espionage experience. They could work together undercover and take down the bad guys from the inside.
Well, it could involve Ethan Hunt trying to stop a terrorist group from stealing a powerful new weapon that can control the world's communication systems. He'd have to go undercover in the group, face a lot of dangerous situations and high - speed chases, and of course, use his amazing spy skills to save the day.
Yes, it is possible. You could create a scenario where Naruto characters are involved in a Mission Impossible - like mission. For example, Naruto could be tasked with infiltrating a highly guarded enemy base, much like Ethan Hunt in Mission Impossible. His ninja skills such as stealth, transformation jutsu, and high - speed movement would be very useful in such a mission.
Well, perhaps in this fanfiction, there's a multiverse rift that pulls Nightwing into the Avengers' world. The Avengers initially mistake him for an enemy, but after some misunderstandings are cleared up, they realize his skills. Together, they face a new threat created by a combination of Hydra and some of Nightwing's rogues gallery who have also crossed over. Nightwing could teach the Avengers some stealth tactics while they show him how to handle more powerful cosmic threats.
One possible plot could be that the Shikon Jewel gets scattered across the Marvel universe. Inuyasha and his friends, like Kagome, have to team up with the Avengers to retrieve the pieces. Iron Man might be intrigued by Inuyasha's sword and try to study it, while Captain America could admire Inuyasha's fighting spirit. They'd face villains who also want the power of the Shikon Jewel, creating an epic adventure.
One possible plot could be that the Voltron team gets transported to the Avengers' universe. They might initially be seen as threats, but then they realize they need to team up to fight a common enemy, like a powerful alien force that's too much for either group alone. The Voltron lions could combine in the middle of New York City, creating an amazing spectacle.
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.
