In many fanfictions, Izuku and the Hero Killer have a complex relationship. Sometimes, Izuku might be portrayed as trying to understand the Hero Killer's motives, which are often misconstrued but rooted in a desire for 'true' heroism. This can lead to some really interesting character development for Izuku as he grapples with his own ideas of heroism in the face of such a radical view.
Strength is a key factor. If a hero in a historical romance is physically strong and an excellent fighter, like a knight or a warrior, that can make him 'killer'. For example, a hero who can defeat multiple foes in a sword fight. Another aspect is his confidence. A self - assured hero who can charm the heroine and outwit his rivals easily can be seen as 'killer'.
The Hero Killer, on the other hand, has a more radical ideology. He thinks that many so - called heroes are false, only in it for fame or money. In fanfictions, his actions of targeting heroes he deems unworthy are a clear manifestation of his beliefs. His ideology challenges Izuku's in a way that forces Izuku to re - evaluate what it really means to be a hero.
It would make his hero journey much more complex. He'd have to constantly prove that he's not going to use the quirk in the wrong way. The public might be skeptical of him at first. But if he can show that he's still the same Izuku at heart, just with a new tool to fight villains, he could win them over.
Well, if Izuku gets the Hero Killer's quirk in fanfiction, he might face a lot of internal conflict. On one hand, his original goal of being a hero is all about saving people with a smile. But the Hero Killer's quirk is more about punishing those who are 'false heroes'. Izuku would have to struggle with how to use this new power in a way that aligns with his values. Maybe he'd try to reform the quirk's nature, using it to expose real villains who are hiding among the heroes instead of attacking heroes directly.
There could be some benefits. For one, it can enhance your critical thinking skills as you try to analyze the motives and actions of the serial killers in the stories. Also, it might increase your awareness of safety. If you understand how these killers operate, you can be more vigilant in your own life. However, it's important to note that some people might find it disturbing, so it's not for everyone.
Well, for a great villain killer OC in My Hero Academia fanfic, think about their motivation deeply. It could be revenge for a lost loved one due to a villain attack. In terms of appearance, make them stand out. For example, they could have a scar across their face from a past encounter with a villain. Their fighting style should be interesting too. Maybe they use a combination of martial arts and their quirk in a very unorthodox way that catches villains off guard.
One plot idea could be that your OC is wrongly accused of being a villain because their methods of killing villains are too extreme for the hero society. They then have to prove their innocence while still continuing to hunt down the real villains. Another idea is that a powerful villain organization puts a bounty on your OC's head, and they have to fight off assassins while also taking on the main villains.
One great 'Batman x Killer Frost Fanfiction' is 'Frosty Encounters'. It has an interesting plot where Killer Frost is forced to team up with Batman against a common enemy. The author does a great job of exploring their dynamic, with Batman being his brooding self and Killer Frost having her cold and snarky attitude.
