Naruto himself is very likely to be involved. He's the main character of his series and his unique abilities like the Rasengan and shadow clones would make for great interactions. Sasuke is also a top candidate. His Sharingan and his dark past could create interesting storylines when combined with hero concepts. Sakura, with her medical ninjutsu and strength, could also be involved, perhaps teaming up with a hero who has a similar healing - based power.
Definitely Naruto. His determination and growth throughout the Naruto series make him a perfect candidate for crossovers. Rock Lee could be another one. His hard - working nature and unique fighting style, like the use of taijutsu only, could be an interesting contrast to the powers of heroes. Kakashi too. His Sharingan and his experience as a ninja could bring a lot to a crossover. He could mentor a young hero or learn new things from the hero's world.
In 'naruto heroes crossover fanfiction', aside from Naruto, Hinata could be involved. Her Byakugan ability and her shy yet strong - willed personality could lead to some interesting character dynamics. Gaara is also likely. His ability to control sand and his past as a loner could be explored in the context of a crossover. He could find new friends or allies among the heroes. And of course, Jiraiya, with his vast knowledge and pervy but wise personality, could have some really funny and engaging interactions with heroes.
Homer Simpson is very likely to be involved. He's the main character and his bumbling yet loveable nature can create a lot of comical situations in crossovers. For instance, if it's a crossover with 'The Flintstones', Homer would probably be trying to out - eat Fred Flintstone at the local diner.
Naruto himself is the most obvious one. Since it's a Naruto - related fanfic, he would likely be at the center of any crossovers with god - like entities. His strong will and desire to protect his village make him a prime candidate for interacting with powerful gods.
Well, characters like Jiraiya could be really interesting in a 'naruto crossover godlike fanfic'. He has a lot of knowledge about the ninja world and different powers, so his encounter with god - like beings would be full of potential for interesting stories. Tsunade too, as a powerful Hokage, could be involved. She could represent the Naruto world's power structure when dealing with these otherworldly god - like entities. And then there's Orochimaru, who is always seeking more power, so he would be very likely to get involved in any situation where there are god - like powers to be had.
Well, obviously Naruto himself is the central character. Sasuke could be involved as he has a complex relationship with Naruto. In a crossover, if Naruto is betrayed and ends up in the Dragon Ball universe, Vegeta might be a character he interacts with. Vegeta could initially see Naruto as a weakling but later come to respect his skills. Another character could be Luffy from One Piece. If Naruto is betrayed and crosses over to the One Piece world, Luffy would likely befriend him and help him out, seeing Naruto's situation as similar to his own crewmates' struggles.
Definitely Hellboy himself. He's the central character from his own universe and would be the main connection to the crossover. Then, Batman is a likely candidate. His detective skills and his willingness to work with 'outsiders' would make him a great fit. He could be intrigued by Hellboy's nature and abilities.
The villains from 'the real ghostbusters' like Gozer or Vigo could play a big part. In a crossover, they might team up with villains from the other franchise, creating a more powerful and menacing force for the Ghostbusters to face. And let's not forget Janine. She could be involved in some administrative or behind - the - scenes role in the crossover, providing support to the Ghostbusters while also interacting with new characters.
I think the Task Force members from Death Note could be involved in scp death note crossover fanfiction. They were always in the middle of the chaos caused by Light and the Death Note. In the SCP world, they would have to deal with not only Light but also the various SCP threats. Also, SCP - 105 could be an interesting addition. Her ability to interact with photographs could potentially be used in relation to the Death Note. Maybe she could take pictures of the names written in the Death Note and use it in some strange way.
Iruka and Mizuki are also possible characters for role reversal in fanfiction. Iruka could be the one with some hidden, not - so - good motives, while Mizuki could be the kind - hearted teacher figure. This would turn the early Naruto story on its head, as Iruka was Naruto's first positive influence in the original series. The new dynamic between Naruto and these two reversed characters would open up a whole new set of story possibilities.
Obviously Naruto himself. Then his parents, Minato and Kushina. His wife Hinata and their children would also be part of it. Jiraiya could also be involved as he was like a father figure to Naruto. And maybe some of the remaining Uzumaki clan members if they are still alive in the fanfiction. Also, characters like Iruka, who was an important person in Naruto's early life, could be there to witness the family reunion.
Obviously, Naruto himself is central. His family like Hinata and Boruto would be very likely to be involved. Sasuke is also a key character as Naruto's friend and ally. Kakashi, being Naruto's former teacher, could also play a role. Shikamaru, as Naruto's advisor, would be important in any political or strategic situations. And then there are the other members of the Konoha 11, like Sakura who could be involved in medical support or combat situations if needed.
