Well, in a fanfic where an OC has Wolverine's powers against the Joker, it could start with the OC being in Gotham. The city's dark and gritty nature would contrast with the OC's more animal - like and straightforward power set. The Joker would likely try to use the OC's short temper (a trait Wolverine sometimes shows) against them. Maybe he'd set up situations that would make the OC lash out and cause destruction, which would then turn the city against the OC, putting them in a tough spot.
The OC would probably be initially enraged by the Joker's antics. Wolverine - like powers mean a short fuse sometimes, and the Joker's chaotic behavior would surely set that off. But as the story progresses, the OC would have to learn to control their temper to effectively deal with the Joker.
In this fanfiction, the prototype powers could be something like an early form of chakra manipulation that is different from the traditional Naruto world's chakra use. It might be more raw and unrefined, with the potential for new and unique jutsu.
Imagine Naruto with all those alien fanfic powers. He could have the power of super strength like some hulking alien species, or the ability to turn invisible like certain stealthy aliens. His combat style would be a wild mix of ninja techniques and alien powers. He could shoot energy beams from his hands or teleport across long distances without using ninja techniques. This would make him a force to be reckoned with not only in his own world but potentially across the universe in a much broader sense.
His hidden powers might be the ability to control all five basic nature types without any training. In the original story, Naruto had to work hard to master different nature types. But in a fanfiction, it could be that he has this innate ability which was hidden all along. This would make him extremely powerful and feared by his enemies.
In some fanfictions, Naruto's multiverse powers are portrayed as a way to bring together different versions of himself. Each version has its own set of skills and knowledge. By merging these aspects, he becomes an even more powerful and complex character, able to solve problems that were previously insurmountable.
Perhaps he has the power of elemental control. So, he can manipulate fire, water, air and earth. For example, he could use fire to create barriers or water to douse dark magic attacks. It makes the story more exciting as he has new ways to fight against evil forces.
Well, he could use Freddy's power of entering people's dreams to fight his opponents in the dream realm. Maybe he would trap his enemies in a never - ending nightmare, causing them mental distress and weakening their will to fight in the real world.
One possible new power could be the power to absorb and use any chakra, regardless of its origin. This would make him extremely powerful as he could draw from the chakra of his enemies or even from natural sources like the sun or the earth. He could also gain the power of telepathy on a large scale, being able to communicate with anyone in the world or even across different dimensions. Additionally, he might obtain the power of instant teleportation to any place he desires, which would give him a huge advantage in battles and travels.
