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.
A fanfiction could focus on a friendly rivalry between Ryu and Sakura. They might compete in local street fighter tournaments. Sakura is always eager to prove herself against the more experienced Ryu. And in the process, they both learn respect for each other's fighting styles.
A third plot idea is a crossover with the 'Final Fantasy' universe. Ryu could be transported to a world filled with magic and monsters. He would have to team up with the Final Fantasy characters to fight against a common enemy, perhaps using his Hadouken in combination with magic spells.
They could team up to face a common enemy. For example, a new villain emerges in the Street Fighter world. Ryu and Sakura decide to join forces. Ryu's powerful hadokens and Sakura's energetic punches combine to create a formidable fighting duo.
In a fanfiction, their relationship could also develop through shared experiences outside of fighting. Say they both get involved in a community project in their respective villages. They start to understand each other's values and goals in life, not just in combat. This helps them see each other in a new light and their relationship can grow from there. They might start to communicate more, and over time, feelings of friendship or more could emerge. Also, they could have misunderstandings at first, like Ryu thinking Chun - Li is too strict in her training methods while Chun - Li might think Ryu is too reckless. But as they work through these differences, their relationship deepens.
While we can't completely rule out the possibility, it seems very improbable for an official love story to develop between Ryu and Chun - Li in Street Fighter's future. The brand has a certain image and set of expectations. Their characters are so iconic in their own right, with their own goals and values that don't really lead towards a romantic relationship in the traditional sense. But who knows, with the evolving nature of storytelling in video games, perhaps there could be some very minor hints or nods in that direction in the far future, but not a full - blown love story.
One idea could be a story where Ryu and Chun - Li are forced to team up for an underground fighting tournament that has a mysterious organizer. They start off not getting along well because of their different fighting styles and philosophies. But as they face tougher opponents together, they begin to respect each other more and learn from one another.
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.
Title: 'The Clash of Titans: MK vs Street Fighter'. In this fanfiction, Ryu from Street Fighter finds himself in the Mortal Kombat realm. He's shocked by the brutal nature of the battles there. He meets Scorpion, and at first, they are hostile. But as they realize they both fight for justice in their own ways, they decide to team up against a common enemy, Shang Tsung, who has plans to invade both their worlds. They combine their fighting styles, Ryu's Hadoken mixing with Scorpion's Spear, creating a new and powerful attack to defeat Shang Tsung.
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.
