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.
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.
It could be Akuma. His Satsui no Hado gives him incredible power and his fighting skills are top - notch. In a crossover, he could easily adapt to the Mortal Kombat's more brutal fighting style and use his dark powers to overpower many opponents.
It could be Arya Stark. In Game of Thrones, she has proven to be a highly skilled assassin. In a Mortal Kombat crossover, her ability to change faces and sneak up on her enemies would be a great advantage. She could use her Needle sword and her skills learned from the Faceless Men to take on opponents. And her list of names of those she wants to kill could easily be added to with Mortal Kombat villains.
Scorpion would be very interesting. Scorpion has a tragic backstory and his hellish powers are a great contrast to Kenshi's more earthly - based sword and telekinesis skills. Their interaction could be full of tension at first, as Scorpion is often distrustful, but they could learn from each other and become a powerful force. For example, Scorpion could teach Kenshi some of his stealthy combat moves, while Kenshi could show Scorpion how to better control his rage using telekinesis.
It's really hard to say for sure. Shao Kahn from Mortal Kombat is extremely powerful with his brute strength and magical abilities. But then you have characters like M. Bison from Street Fighter who has powerful psychic powers. If we consider a crossover, it might depend on the rules of the world they are in. In a world more based on Mortal Kombat's rules, Shao Kahn might have the edge, but in a more Street Fighter - like setting, M. Bison could be more dominant.
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.
Scorpion from Mortal Kombat could be a very interesting character in this crossover. His hellish powers and his quest for revenge could put him at odds with some of the Naruto characters. His battles with Naruto or Sasuke would be intense, especially with his ability to teleport and use his kunai chain.
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.
Ermac can be characterized as a powerful and mysterious figure. His telekinetic powers would make him stand out in any crossover. He would be seen as a force to be reckoned with, and his stoic nature would add to his allure. In a crossover, he might be the silent observer at first, trying to understand the new world he's in.
First, know Scorpion's character well. His backstory of revenge and his loyalty to the Shirai Ryu clan are important aspects to keep in mind. Then, when choosing the crossover element, make sure it complements his character. For example, if it's a crossover with a fantasy world, you can play with the idea of Scorpion's hellish powers in a world full of magic.
