Well, a great plot could be that the Infinity Stones start to mess with the fabric of reality and it creates a portal between the Naruto universe and the Marvel universe. The Avengers and Naruto's friends end up in each other's worlds. Naruto and the Avengers have to work together to fix the portals and return everyone to their proper universes. Along the way, Naruto might have some epic battles with villains like Loki, using his ninja speed and strength. And the Avengers could learn a thing or two about chakra from Naruto and his friends.
One possible plot could be that the Avengers are somehow transported to the Naruto universe. They team up with Naruto and his friends to fight a common enemy like Kaguya who has somehow obtained the Infinity Stones. The Avengers' powers and technology would be a huge shock to the Naruto world, and they'd have to learn to combine their skills to succeed.
One possible plot could be that Naruto is somehow transported to the Marvel universe. The Avengers initially mistake him for a threat. But Naruto, being Naruto, tries to explain his situation. He then shows them his ninja skills like shadow clones and Rasengan. Together, they could face a common enemy like Thanos, who has acquired some sort of ninja - like powers. Naruto's ability to never give up and his strong will could inspire the Avengers, and his combat skills could be a great addition to their team in the fight.
A cool plot might be that the Tailed Beasts in the Naruto world are being targeted by an unknown force from the Marvel universe. The Avengers, thinking it could lead to a greater threat to both universes, come to help. Naruto and the Avengers have to work together to protect the Tailed Beasts. Hulk could have an interesting interaction with the Tailed Beasts, perhaps learning from them how to better control his rage, while the ninjas are amazed by Thor's lightning powers and try to incorporate some of that into their own jutsu.
Well, perhaps there's a threat that can only be defeated by combining the chakra in the Naruto world with the superpowers of the Avengers. For example, Thor's lightning could combine with Sasuke's lightning - based attacks. And Captain America's leadership could inspire Naruto to lead his own team in a new way. They all start off not trusting each other much, but as they face challenges together, they learn to work as one.
One possible plot could be that a powerful villain from another dimension threatens both the DC and Marvel universes. Superman and the Avengers have to put aside their differences and combine their powers. For example, Superman's super strength and flight could be paired with Thor's godly abilities and Captain America's leadership. They could start off not trusting each other, but as the battle progresses, they learn to work together and defeat the villain in an epic showdown.
A cool plot could be that a villain creates a device that can manipulate time. This device causes chaos as it starts to merge different timelines. Spider - Man gets caught in the middle of this temporal mess while on a normal patrol in New York. He then reaches out to the Avengers for help. The Avengers, who have experience with time - related issues from previous adventures, team up with Spider - Man. Thor uses his lightning to disrupt the device's power source, while Spider - Man swings in to physically disable it with the help of Black Widow's combat skills. In the end, they manage to restore the timelines and save the day.
One idea could be that the Pokemon are brought into the Naruto world and are seen as strange chakra - infused creatures. Naruto himself could befriend a Pikachu - like Pokemon that has a special jutsu - like ability. For example, it could use electric attacks in a way similar to how Naruto uses his Rasengan. The Pokemon trainers could be seen as a new type of ninja, with their Pokemon being their summons.
One possible plot could be that Naruto and his friends are transported to the Pokemon world. Naruto, with his never - give - up attitude, decides to become a Pokemon trainer. He might choose a Pikachu as his first Pokemon because of its similarity to his own energetic nature. Along the way, he meets Ash and they team up to face a new evil organization that is trying to use Pokemon and Ninja techniques for their own dark purposes.
One possible plot could be Naruto being transported to the Marvel universe. He might initially be confused but then quickly adapt his ninja skills to the new world. For example, his shadow clone jutsu could be used in a battle against some of the street - level villains in Marvel like the Hand. His ability to quickly move and his chakra control could make him a formidable ally or a target for those who want to study his powers.
A cool plot might involve an enemy that uses both Chakra and Infinity Stones' power. Naruto teams up with the Avengers. The Avengers are amazed by Naruto's ability to use his Nine - Tails' Chakra. Naruto, on the other hand, is in awe of the high - tech weapons and superpowers of the Avengers. They combine their powers and skills, with Iron Man creating special suits for Naruto that can enhance his jutsu, and together they fight the powerful foe.
