Here's a plot idea. There's a powerful artifact in the Mortal Kombat crossover world that Reptile believes can restore his homeland. However, other characters from both Mortal Kombat and the other side of the crossover also want it for their own reasons. Reptile has to use his wits and his combat skills to outmaneuver them. He forms some unlikely alliances along the way. Some characters might try to double - cross him, and he has to figure out who to trust. As he gets closer to the artifact, he discovers that it has more power than he ever imagined and could change the entire crossover universe.
One plot could be that in the Mortal Kombat crossover fanfiction, Reptile is hunted by a group from the other side of the crossover because they think he's a threat. But in reality, he's just trying to protect his own kind. As he runs, he meets up with some Mortal Kombat characters who initially don't trust him. But as they face common enemies together, they start to work as a team. Along the way, Reptile has to deal with his own inner demons and the prejudice of the new characters he meets.
A possible plot could be that Reptile discovers a portal to another world as part of the crossover. He enters it out of curiosity or in search of power. Once in the new world, he finds himself in the middle of a conflict. He has to choose sides, either with the Mortal Kombat characters or those from the other side of the crossover. His loyalty is tested as he uncovers secrets about both sides.
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.
In a Mortal Kombat crossover fanfiction, Reptile can add a lot of depth. He's a complex character with his own motives. In the crossover, he could be on a quest to find something that was lost in the merging of the two universes. His appearance might be different too, adapting to the new environment. He could start off as an antagonist, but as the story progresses, find common ground with the other characters. His fighting style could evolve as he learns new moves from the crossover characters, making him even more formidable in battles.
Perhaps Kenshi enters the Mortal Kombat world during a tournament. He is drawn to the power and chaos of the tournament. He decides to participate not only to test his skills but also to find a way back home. Along the way, he meets Kitana and they form an unlikely alliance. Kenshi helps Kitana with his strategic mind and combat skills, while she teaches him about the politics and power dynamics of the Mortal Kombat world.
Well, it could be about Naruto characters being thrown into the Mortal Kombat tournament. Maybe Naruto has to fight against Scorpion using his shadow clones and Rasengan. Sasuke could use his Sharingan to counter the special moves of Sub - Zero.
A cool plot could involve Akuma from Street Fighter accidentally being transported to the Mortal Kombat realm. There, he's seen as a new threat, and Sub - Zero decides to take him on. But during their fight, they realize that there are greater forces at work trying to start a war between the two realms. So instead of fighting each other, they join forces, along with other fighters like Ken and Johnny Cage, to stop the real enemy that wants to see both worlds destroyed.
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.
One possible plot could be that Naruto, feeling neglected in his own world, somehow gets transported to the Mortal Kombat universe. There, he might initially struggle to adapt to the extreme violence and different rules. He could start as an outcast, just like he sometimes felt in Konoha, and gradually learn the ways of Mortal Kombat. Maybe he'd team up with some of the more morally - gray characters in Mortal Kombat who understand his sense of being an outsider. His ninja skills could be both an advantage and a hindrance as he tries to survive in this new and dangerous world.
One possible plot could be that Naruto is somehow transported to the Mortal Kombat universe and is banished there by some powerful force in his own world. Maybe it's a result of a failed jutsu or a curse. He then has to survive in this brutal new world, learning the ways of Mortal Kombat while also trying to find a way back home. He might face off against classic Mortal Kombat characters and use his ninja skills in unique ways.
Perhaps in the fanfiction, Female Scorpion is a time - traveler. She gets sent back in time to a crucial moment in Mortal Kombat history. There, she has to use her skills and knowledge to prevent a catastrophic event from happening. This could involve fighting against her own ancestors or teaming up with long - dead heroes. It would be a great opportunity to explore different eras of the Mortal Kombat world.
