Uraraka might also be a great friend for Killua. She has a bubbly personality that could balance out Killua's more stoic nature. And she's not afraid to jump into action, which Killua would respect.
I think Midoriya could be his best friend. Midoriya is kind - hearted and always looking to learn, which would appeal to Killua. They could bond over their shared desire to become stronger and protect others.
Kirishima could be a good match too. Kirishima's strong sense of loyalty and his straightforward attitude would mesh well with Killua. They could train together and encourage each other to be better heroes.
Maybe Killua enters the My Hero Academia world during the sports festival. He decides to participate just for fun, but his skills quickly make him a standout. He could face off against Bakugo and show Bakugo a whole new level of combat intensity. This encounter might make Bakugo respect Killua and also force him to reevaluate his own skills.
One interesting Killua in My Hero Academia fanfiction is 'Killua in the World of Heroes'. It has an exciting plot where Killua's assassin skills blend into the MHA universe. He teams up with Deku and they face off against new villains created specifically for this crossover. It's a great read for those who like to see different universes collide.
The contrast. Killua from his original series has a very different background and set of skills compared to the characters in My Hero Academia. When he's placed in the MHA universe, it creates an interesting dynamic. His assassin - like abilities and cold - blooded nature at the start make for a great contrast against the more idealistic heroes in MHA.
Killua has a very stealthy side to him as well. In a My Hero Academia fanfiction, this could be manifested as a quirk that allows him to become invisible or at least very difficult to detect. He could use this in combination with his speed to surprise enemies. It would also be interesting to see how he would interact with other characters like Deku and Bakugo, perhaps teaching them some of his combat techniques.
He could be a transfer student. Just like how many characters join UA High, Killua could transfer in with his unique set of skills. He would be the cool and mysterious new guy that everyone is curious about.
Gon in fanfiction can be very single - minded in his pursuit of goals, just like in the original. He might be a bit more naive at times, which can lead to interesting plot twists. Killua is often portrayed as having a complex emotional side. He struggles with his past as an assassin and his loyalty to Gon. His cool exterior may crack in some fanfictions, showing his true feelings.
Yes, there are likely some fanfictions out there with such a concept. Fanfiction writers often come up with creative crossovers. You can try searching on popular fanfiction websites like Archive of Our Own or Fanfiction.net.
One popular plot twist could be Killua going back in time and accidentally changing something that has a huge impact on his relationships. For example, he might prevent himself from meeting Gon in the first place, and then has to figure out how to get their friendship back on track. Another could be that he goes back to a time when a great evil was just starting, and he has to stop it before it gets out of hand, which completely changes the future he knew.
Killua could potentially adapt his Nen abilities to the magic system in Fairy Tail. His Lightning Palm, for example, could be seen as a form of lightning - based magic in the Fairy Tail world. He might be able to combine his assassin skills with the magic knowledge of Fairy Tail. Maybe he'd learn some new spells or techniques from the wizards there to enhance his own fighting style.
No, it's not appropriate. Fanfiction should focus on positive aspects such as character development, new adventures, or exploring relationships in a non - explicit way. Sexualizing a character in fanfiction goes against the spirit of most fandoms which are often family - friendly or at least should be respectful of all ages.
