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.
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.
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.
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.
The plot of such fanfiction might revolve around a tournament. Imagine the Predator being invited or lured into the Mortal Kombat tournament. The other Mortal Kombat fighters would initially be confused by this new and strange opponent. But as the battles progress, they would learn to adapt to the Predator's hunting tactics. This could lead to some great character development as they face this extraterrestrial threat.
In Mortal Kombat 11 crossover fanfiction, some of the most popular crossover characters are from other fighting games like Street Fighter. For example, Ryu. His unique fighting style and the contrast between his more disciplined and honorable approach compared to Mortal Kombat's often brutal and underhanded tactics make for interesting fanfic scenarios. Another popular one could be characters from DC Comics if there's a crossover in that regard. Superman or Batman can bring a whole new dynamic to the Mortal Kombat universe with their superpowers and detective skills respectively.
In Mortal Kombat Cassie Cage fanfics, the theme of heroism is quite common. Cassie is depicted as a hero, saving the day in various situations. Her relationship with her parents, which is a part of her backstory, is also a frequently explored theme. It can add depth to her character. Another common theme is the exploration of her powers. Fanfics often show her discovering new abilities or mastering the ones she already has. And the theme of facing challenges and overcoming them is also prevalent, as she has to deal with many tough opponents and difficult situations in the Mortal Kombat world.
Another interesting crossover could be with a superhero universe, say the Marvel universe. Picture Scorpion facing off against Spider - Man. Scorpion's hellish powers and acrobatic fighting style would make for an intense battle against the web - slinger. He could be there because he's been summoned by some dark magic that is affecting both worlds.
One great storyline could be a Mortal Kombat 11 and Resident Evil crossover. Imagine the Mortal Kombat warriors having to fight through a zombie - infested Outworld. They would have to use their combat skills not only against the undead but also against any Resident Evil villains that might be lurking. Another interesting one is a crossover with Star Wars. The Jedi and Sith powers would be a fascinating contrast to the Mortal Kombat magic and combat. For example, a lightsaber duel between a Mortal Kombat character and a Jedi Knight.
Well, one possibility could be that Naruto characters are transported into the Mortal Kombat universe. Naruto, with his Rasengan, could face off against Sub - Zero's ice powers. Maybe they have to fight in Mortal Kombat tournaments to find a way back to their own world. It would be interesting to see how Naruto's ninja skills stack up against Mortal Kombat's brutal fighting styles.
