Well, in this fanfiction idea, Naruto becoming Shao Kahn would be a wild transformation. Naruto is used to his world of ninjas and elemental jutsus, while Shao Kahn rules a dark and brutal realm. Maybe Naruto gets trapped in Shao Kahn's body due to a sorcerer's spell gone wrong. At first, he would be completely out of his element, but his adaptable nature would kick in. He would try to understand Shao Kahn's power and use it for good, like trying to end the constant bloodshed in Outworld and bring some peace, while also having to deal with the enemies that Shao Kahn has made over the years.
Perhaps in this fanfiction, Naruto discovers Shao Kahn's world and is in awe of his power. He then decides to study under Shao Kahn, or at least learn from his philosophy of power and domination. This could lead to Naruto facing a moral dilemma as Shao Kahn's values might conflict with his own ninja way. So he has to figure out how to adapt and still stay true to his friends and village.
The unique aspect is the clash of two very different universes. Naruto's world is full of ninjas, chakra, and honor - based battles. Shao Kahn's world is more about brute force and dark magic. When combined in fanfiction, it creates a really exciting mix.
One great 'Shao Kahn x OC Fanfiction' is 'The Kahn's New Ally'. It has an interesting plot where the OC is a powerful sorceress who catches Shao Kahn's eye. Their interactions are full of power dynamics and political intrigue within the Mortal Kombat universe.
Obviously Naruto would be one of the main characters as the title implies his connection to this fanfiction. And Shao Kahn would also be a main character since Naruto is his fan in this concept.
Obviously, Shao Kahn would be the main antagonist. He is a powerful and tyrannical ruler in his own realm. His thirst for power and domination would put him directly at odds with Naruto, who values freedom and justice. Shao Kahn's brutal methods of ruling and his desire to expand his empire would make him a formidable foe for Naruto.
One possible plot could be that Naruto is transported to Shao Kahn's realm. He initially struggles to understand the brutal and chaotic nature of this new world. But with his ninja skills and never - give - up attitude, he starts to form alliances with some of the oppressed beings there. Together, they plan to overthrow Shao Kahn's tyrannical rule and bring some sense of justice to the realm.
Naruto could adapt by using his strong willpower. He has faced many challenges in his own world, so he would rely on that experience. He might start by learning about Shao Kahn's powers and the politics of Outworld. His ability to make friends quickly could also help him. He could form alliances with some of the more reasonable characters in Outworld who were previously afraid of Shao Kahn.
