What are some interesting plot ideas for 'yoshi x greninja fanfiction'?

A good plot could involve a tournament within the Smash Bros world. Yoshi and Greninja enter as a team, which is unusual. They face tough opponents like Mario and Link. To win, they have to develop new strategies. Yoshi could use his flutter jump in unexpected ways, and Greninja could come up with new water - based attacks. Their journey through the tournament could be filled with both comical and intense moments.

One plot idea could be a race across different dimensions. Sonic, with his speed, Mario, with his jumping skills, and Yoshi, with his unique abilities, could be competing to find a powerful artifact lost in these dimensions. Another could be a team - up to stop an evil force that threatens both their worlds. The evil force might be trying to steal the chaos emeralds from Sonic's world and the power - ups from Mario's world. And a third idea is a friendship - building adventure where they have to help Yoshi find his long - lost family in a strange new land that combines elements of both Sonic and Mario's universes.

Obviously, the main characters are Yoshi and Greninja. Yoshi is a cute and friendly dinosaur - like creature known for its ability to eat enemies and turn them into eggs. Greninja, on the other hand, is a water - type Pokémon with ninja - like skills, being very fast and agile.

One idea is that Greninja is framed for a crime it didn't commit. It then has to go on the run while trying to prove its innocence. Along the way, it teams up with other outcast Pokémon and together they uncover a conspiracy that goes far deeper than they ever expected.

One idea could be that Ash and Greninja's fusion has to battle an ancient evil that threatens the Pokémon world. The fusion might have unique powers that are a combination of Ash's strategic thinking and Greninja's combat skills.

The fanfiction might revolve around a friendship between Yoshi and Greninja. They could start off as rivals in the Smash Bros battles but gradually come to respect and rely on each other. For example, Greninja could teach Yoshi some stealth techniques, and Yoshi could show Greninja how to find hidden power - ups. Their bond could grow stronger as they face various challenges together in the Smash Bros world.

One plot idea could be that the female Greninja has unique powers that only Ash can help her control. As they train together, they develop a deep bond that goes beyond a typical trainer - Pokémon relationship.

One idea could be that Greninja returns with a new power that it gained during its time away. It could use this power to help Ash in a crucial battle in the Alola region. For example, it might have learned to control water in a more unique way, like creating ice sculptures that can attack opponents.

One idea could be to explore Yoshi's origin. Maybe he came from a far - off land before arriving in the Mushroom Kingdom. Another could be a story where Yoshi has to protect a special egg that contains a new type of power - up. Or perhaps a story where Yoshi teams up with some of the less - known characters in the Mario universe.

A Yoshi fanfiction might focus on Yoshi's family. For example, it could be about how Yoshi takes care of his baby Yoshis. He teaches them how to find the best fruits, how to jump high, and how to avoid dangerous enemies. This story could show the tender and nurturing side of Yoshi.
