How about a crossover with the 'Teenage Mutant Ninja Turtles'? Johnny Cage could end up in New York City's sewers and meet the turtles. He'd be initially shocked but then impressed by their ninja skills. They could all work together to stop Shredder from getting his hands on some powerful ancient artifact that Cage was also after.
His character could also be developed through learning new fighting styles. In the crossover, he might encounter a Mortal Kombat master who teaches him a more disciplined and deadly form of combat. This not only makes him a more formidable fighter but also changes his attitude towards fighting. He becomes more respectful of the Mortal Kombat traditions and incorporates them into his own flamboyant style.
For 'johnny cage x mileena fanfiction', a plot might be that Johnny Cage is filming a movie in Outworld as a sort of 'behind - the - scenes' look at the realm. He meets Mileena, who is initially hesitant about being in the movie. But Johnny's charm wins her over. As they work on the movie project, they find themselves in dangerous situations, like attacks from other Outworld creatures. Through these experiences, they grow closer. Mileena shows Johnny a side of Outworld he never knew, and he shows her the lighter side of Earthrealm. Their relationship then develops into a love story that defies the differences between their two worlds.
One idea could be that they go on a secret mission together where they have to pretend to be a married couple. This would lead to some comical and also some tender moments between them as they navigate the challenges of the mission while maintaining their cover. Another plot could be that they train a new group of recruits together and face some differences in their training methods which causes some tension but also helps them understand each other better in the end.
A Luke Cage and Iron Fist crossover fanfiction would also be great. The contrast between Luke's street - level heroism and Iron Fist's more mystical powers could lead to a really engaging plot. Maybe they have to protect an ancient artifact from a group of villains who want to use its power for evil.
A crossover with a fantasy realm could also be cool. Picture Johnny Gat in a world of magic and mythical creatures. He might initially be skeptical of the magic around him but quickly learn to use it to his advantage. He could form an unlikely alliance with a wizard or a warrior elf to defeat an ancient evil that threatens the land.
Batman could be another interesting crossover. Batman's dark and brooding nature would contrast with Cage's more flamboyant style. They could be forced to team up to solve a mystery that involves some sort of magic or otherworldly elements, which would be new territory for Batman and something Cage is more used to in the Mortal Kombat realm.
Maybe Johnny Cage is suddenly part of a Mortal Kombat tournament in a crossover. He uses his acting skills not just for show but as a strategic advantage. For example, he could pretend to be injured to lure opponents into a false sense of security and then strike back with a powerful combo. His showbiz connections could also play a role, like getting access to some special weapons or training techniques that no one else in the Mortal Kombat world has thought of.
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.
One popular idea could be a crossover with the 'Jojo's Bizarre Adventure' universe itself, like Johnny Joestar meeting other Joestars from different parts of the series.

Or perhaps a crossover with a superhero universe, where he uses his Spin abilities in a world full of caped crusaders.
A Johnny Bravo crossover with Dexter's Laboratory would be interesting. Johnny might stumble into Dexter's secret lab, thinking it's some kind of cool hangout. Dexter would be initially annoyed but then they could team up to stop a common enemy, like an evil robot that has escaped from Dexter's lab and is causing chaos in the city. Or a crossover with Courage the Cowardly Dog. Johnny goes to visit Courage's farmhouse and gets caught up in all the spooky happenings there.
