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.
Another idea is that Johnny Cage is involved in a crossover where his movie world and the Mortal Kombat world start to blend. Characters from his movies start to show up in the Mortal Kombat arenas, and vice versa. This causes chaos as the rules of both worlds collide. Johnny has to navigate this strange new situation, trying to keep his friends from both worlds safe while also trying to figure out who or what is causing this crossover in the first place.
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.
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.
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.
One popular storyline could be Scorpion and Mileena teaming up against a common enemy in Outworld. They both have unique fighting skills, and their combined strength would make for an exciting adventure. Maybe they have to face off against a powerful sorcerer who is trying to take over Mileena's realm.
One possible storyline could be that Jade and Smoke are forced to team up against a common enemy in Mortal Kombat. Maybe they start off distrusting each other, as they come from different backgrounds in the Mortal Kombat universe. Jade, being from Edenia, has her own set of values and fighting styles, while Smoke is a Lin Kuei assassin. But as they fight side by side, they gradually learn to respect and rely on each other's skills. Eventually, they form a strong bond and become friends or even something more.
One interesting storyline could be Spider - Man finding himself in the Mortal Kombat tournament. He'd use his acrobatic skills and web - slinging to dodge attacks from Mortal Kombat characters like Scorpion or Sub - Zero. Maybe he teams up with a Mortal Kombat fighter to take on a common enemy, like Shao Kahn who has some evil plan that affects both the Spider - Man universe and Mortal Kombat realm.
A great story idea might be that a common enemy, like a super - intelligent villain who can manipulate time, targets both the Flash's Central City and Batman's Gotham. This forces them to team up. The Flash could use his speed to gather information quickly, while Batman uses his intellect and detective skills to analyze it. They'd have to combine their strengths to take down this powerful foe. For example, Batman could create a device to slow down the villain's time - manipulation powers, and the Flash could deliver it at super - speed.
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.
A possible plot could involve Ermac's past being somehow linked to the crossover world. He discovers that an ancient evil in that world was involved in his creation. So, he goes on a quest to find out the truth and put an end to this evil once and for all. He might face many challenges along the way, like distrust from the locals of the crossover world who see him as a threat.
One idea could be a crossover with Street Fighter. Picture Ryu facing off against Scorpion in a battle of fire and ice. Another could be a Mortal Kombat and DC Comics crossover, where Superman has to deal with the brutality of Mortal Kombat fighters. Or perhaps a crossover with the Castlevania universe, where the dark and gothic elements blend with Mortal Kombat's gore.
