One interesting crossover could be them teaming up to fight a common enemy. Maybe a powerful alien or a super - villain. Their different fighting styles would make for an exciting combination.
There are some interesting ones. You can start by looking on fanfiction websites like Archive of Our Own. Some stories might explore their unlikely friendship, with Johnny's over - the - top bravado and Samurai Jack's stoic nature creating some humorous and action - packed scenarios.
One idea could be that Johnny Bravo accidentally travels to the world of Samurai Jack. He tries to use his charm on the various strange creatures there, but it doesn't work as expected. Meanwhile, Samurai Jack is initially confused by this strange, over - confident man but then realizes they can work together to fight Aku.
A plot could involve a magical item that both Johnny and Jack are after. Johnny wants it for his own glory, thinking it will make him even more of a ladies' man, while Jack needs it to finally defeat Aku. They start off as rivals but then realize they need to work together. Along the way, Johnny learns some lessons about honor and selflessness from Jack, and Jack learns to loosen up a bit from Johnny's carefree attitude. This creates a story full of action, comedy, and character development.
Jack is a man of few words, always thinking about his next move to defeat Aku. Johnny, on the other hand, is constantly talking and trying to be the center of attention. In fanfiction, this could lead to some tense moments where Jack is trying to be stealthy and Johnny keeps blabbing. However, in a fight, Johnny's bravado might actually be an asset. His fearless attitude could inspire Jack to take more risks, and Jack's skills could keep Johnny from getting into too much trouble.
They could start off as rivals. Johnny Bravo thinks he's the coolest and toughest, and when he meets Samurai Jack, he challenges him. Jack, being the stoic warrior, initially ignores him but then realizes Johnny might have some useful, albeit strange, skills. So they start to work together.
A crossover could also involve Naruto teaching Samurai Jack some ninja techniques. Samurai Jack is already a highly skilled warrior, but learning things like stealth and shadow clone jutsu could give him an edge in his fight against Aku. In return, Samurai Jack could teach Naruto about his code of honor and the way of the samurai, which might influence Naruto's approach to battles and his relationships with others.
One interesting crossover could be the unique fighting styles. Samurai Jack's precise and traditional swordsmanship could be combined with RWBY characters' more acrobatic and Dust - enhanced combat. For example, Ruby's scythe - wielding speed might be paired with Jack's strategic strikes.
One interesting crossover could be Jack finding himself in Westeros. He might use his samurai skills to fight in the battles there, like the Battle of the Bastards. His katana would be a fearsome weapon against the swords and axes of Westeros. Maybe he'd team up with Jon Snow, who also has a sense of honor and justice.
Some Johnny Bravo fanfiction stories might revolve around him trying to learn a new skill, like cooking. In this story, he enters a cooking competition and makes a mess of things at first but then discovers his own unique style of cooking. Or perhaps a fanfiction where he meets a girl who is not interested in his usual bravado and he has to change his ways to win her over. Also, a story where he gets superpowers accidentally and has to figure out how to use them without causing chaos.
One great story could be about Johnny Bravo trying to teach Carl some cool new moves. In this fanfiction, Johnny's over - the - top confidence clashes with Carl's more reserved nature, leading to some really funny situations.
