The presence of Dark Naruto in My Hero Academia fanfiction would change things quite a bit. His combat skills and his chakra - based powers would be very different from the quirks in MHA. This could lead to some interesting battles and power - up scenarios. For example, how would heroes like All Might or Deku react to someone with such different powers? Moreover, Dark Naruto's backstory of being an outcast in his own village could parallel some of the characters in MHA who also face discrimination. This could lead to some complex character interactions and story arcs.
If Dark Naruto entered the My Hero Academia fanfiction world, it would disrupt the normal flow. His dark nature might cause chaos among the heroes. Since Naruto's powers are not based on quirks, it would challenge the established system in MHA. He might not follow the rules of hero society, thinking it's similar to the shinobi system that failed him in his original story. Dark Naruto could also influence some of the characters in MHA to question their own beliefs and values. For instance, he might convince some heroes - in - training that the current way of doing things is wrong and there's a need for a more radical approach.
