One possible plot could be that the Akatsuki from Naruto are hired by a powerful and mysterious figure in the Street Fighter world to disrupt a major martial arts tournament. Naruto and his friends, along with some Street Fighter characters like Ryu and Ken, have to team up to stop the Akatsuki's evil plans. They face challenges like learning each other's fighting styles and dealing with the Akatsuki's unique abilities.
One popular Naruto x Street Fighter fanfiction might be one where Naruto characters learn the unique fighting styles of Street Fighter characters. For example, Naruto could learn Ryu's Hadoken and incorporate it into his own fighting style, creating a whole new and exciting combat dynamic.
Chun - Li and Sakura could be a great pairing. They are both strong female characters. Chun - Li with her lightning - fast kicks and Sakura with her powerful punches (after she trains with Tsunade). They could exchange fighting techniques and also bond over their determination to protect their respective worlds and the people they love.
It's really hard to say. Ryu has his powerful Hadoken and other special moves, but Naruto has the Nine - Tails' chakra at his disposal. If we consider raw power, Naruto with his full Nine - Tails form would be extremely powerful. He could cause massive destruction with his Tailed Beast Bombs. However, characters like Akuma also have insane power levels with his Raging Demon move. So it really depends on how you define power in this crossover context.
One idea could be a crossover between Street Fighter and a popular anime like Naruto. Imagine Ryu training with Naruto to master new forms of energy control. Another could be a crossover with the DC Universe, where characters like Chun - Li team up with Wonder Woman to fight a common enemy. Or perhaps a crossover with the world of Final Fantasy, with Street Fighter characters embarking on a magical quest in a fantasy realm.
Maybe Naruto is transported into the Street Fighter world. He could use his ninja skills in the Street Fighter battles, like using his shadow clones to confuse opponents. And perhaps he teams up with some of the Street Fighter characters to fight against a common enemy.
I'm not sure about a specific 'Naruto is a Street Fighter' fanfiction to recommend. You could try searching on fanfiction websites like FanFiction.net or Archive of Our Own. They usually have a wide variety of fan - made stories.
One common theme is the clash of different fighting styles. The ninjutsu of Naruto characters and the martial arts of Street Fighter characters create really cool battle scenes. For example, Sasuke's lightning - based attacks against Chun - Li's lightning - fast kicks.
Luffy from 'One Piece' could also be an interesting crossover. Luffy's stretchy abilities combined with Ryu's martial arts would make for some unique fight scenes. They could also learn from each other's determination and loyalty to their friends.
First, decide which two universes you want to cross over. For example, if it's Street Fighter and Pokemon. Then, think about how the characters will interact. Maybe Blanka discovers a Pikachu in the forest and they become friends. Next, create a plot. It could be that an evil organization is trying to capture both Street Fighter characters and Pokemon. Start with a strong opening that grabs the reader's attention, like a fight scene between two well - known characters from each universe.
