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.
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.
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.
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.
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.
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.
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.
Sure. The backstory of Street Fighter 2010 involves various elements such as the characters' origins, past conflicts, and the circumstances that led to the events in the game. It adds more layers to the overall narrative.
