In fanfiction, Dark Shadow could also be given new powers or abilities. It might be able to split into multiple smaller shadows, each with its own unique characteristics. This would not only make for exciting fight scenes but also open up new storylines about how Tokoyami would control and utilize these new forms of Dark Shadow.
Dark Shadow is a really interesting character. In fanfiction, we can explore its potential in different ways. For example, it could be given more complex emotions and motives. Maybe it has a hidden side that we haven't seen much in the original series, like having a fear of being alone which drives some of its actions.
A cool idea for a Dark Shadow fanfiction could be a story where Dark Shadow gets separated from Tokoyami and has to find its way back. During this journey, it discovers things about itself and the world that it never knew before.
One common theme is the corruption within the hero society. Your dark OC can be a tool to expose the seedy underbelly of how heroes are really like. Another theme is the struggle between good and evil, but from the perspective of the OC who might not see things in such black - and - white terms. Revenge is also a popular theme. Maybe the OC has a vendetta against a certain hero or the hero system in general.
Yo Shindo in My Hero Academia has a lot of potential for interesting fanfiction. His unique quirk makes for great storylines. For example, a fanfiction could focus on his training to better control his vibrations. He could face challenges that force him to push his quirk to new limits, which would lead to his character growth both in terms of power and personality.
Izuku Midoriya could be a great main character in a magic - infused fanfiction. Imagine if he discovers he has an innate magical ability on top of his One For All quirk. He could use magic to further enhance his physical abilities or develop new techniques. His determination and growth throughout the story would be even more exciting with the addition of magic.
Stain could be considered as an anti - hero in fanfiction. His extreme views on heroes, while not entirely acceptable, could be delved into deeper. He believes that only true heroes should be recognized and is willing to take extreme measures to prove his point. A fanfiction could explore a different side of him, perhaps one where his actions are more nuanced.
It might explore character relationships by putting characters in unexpected situations together. For example, if two rivals are forced to team up because of a common enemy. This would force them to see each other in a new light and could lead to the development of a new friendship or at least a grudging respect.
In many Dabi x Toga fanfictions, their relationship is often depicted as complex and intense. They are both anti - heroes/villains in the 'My Hero Academia' universe. Some fanfictions might explore how their shared experiences of being on the 'wrong side' of society bring them closer. For example, they both have had difficult pasts that made them the way they are. Dabi's past with his family and Toga's struggle with her abnormal quirk and society's rejection of it could be a common ground for them to bond over.
Dark Naruto in My Hero Academia fanfiction would be an outsider. He doesn't have a quirk in the traditional MHA sense, but his ninja abilities are on a par with some of the most powerful quirks. His personality would be a mix of his Naruto - self and his darker side. He could be cynical about the hero society in MHA, seeing it as just another version of the shinobi world that he had problems with. He would be a character that causes a stir wherever he goes. His actions would be unpredictable, as he could switch from helping someone one moment to causing trouble the next, all depending on his own internal struggles and how he views the situation at hand.
They could be really good friends. They respect each other's abilities in the series, and in fanfictions, this could develop into a deep friendship. They might study together, train together, and always have each other's backs during battles.
One negative impact is that it can corrupt the original positive image of My Hero Academia. The series is known for its inspiring storylines about heroism, and this kind of fanfiction with inappropriate content can taint that. Another is that it may expose younger fans to adult - like content that they are not ready for.
