If Naruto was in a WoW fanfic, his powers would likely be adjusted to fit the game's mechanics. His shadow clones could be more like summoned minions in WoW. They could have different abilities based on the skills he acquires in the WoW world. His ability to sense danger, which is related to his ninja training, could be translated into a form of danger perception in WoW, helping him avoid traps and enemy attacks more effectively.
Naruto's powers would go through some significant changes in a WoW fanfic. His Nine - Tails chakra could be seen as a very powerful and dangerous form of magic in WoW. However, he would need to learn how to control it within the rules of the WoW world. His taijutsu skills could be combined with WoW - style combat, allowing him to perform unique melee attacks. He might also discover new powers or abilities by interacting with WoW - specific items and locations.
