Well, it's highly likely that such a fanfiction exists. Fanfiction authors are known for their creativity in combining different universes and characters. Since Naruto is a popular anime character and Leon could be from various other works, it's not far - fetched to think that a fan has written a story where Naruto has an admiration for Leon. You can try using search engines specific to fanfiction, like Wattpad as well, to look for it.
There is a good chance that Naruto and Leon fanfiction exists. Fanfiction communities are vast and diverse, with writers exploring all kinds of combinations. The two characters from different franchises can offer interesting possibilities for storytelling. It's worth exploring different fanfiction archives and using relevant tags like 'Naruto', 'Leon', and 'crossover' to find relevant stories.
It's not appropriate at all. Fanfiction should be a creative and positive exploration of the original work, not a medium for inappropriate content. There are so many other positive ways to engage with the 'Leon: The Professional' concept without delving into sexual fanfiction.
Hunnigan could be a great addition. She could provide Leon with information and support from the outside, and her presence could add some tension as she might be suspicious of Ada's motives. Another good character is Wesker. His past connection to Ada could create more drama and conflict in the story. He could be a shadowy figure trying to manipulate the situation between Leon and Ada.
Well, in many Leon fanfiction, his relationships are a big part of it. Some might explore his friendship with Claire or his more complex interactions with Ada Wong. There are also stories that take him out of his usual setting and put him in a modern - day city dealing with a new kind of threat that is not related to the typical zombies or bio - organic weapons he usually faces.
A fanfiction might explore how Leon and Ashley deal with the trauma they endured during the events of the game. They support each other, and Leon teaches Ashley some self - defense moves. Their relationship grows from a protector - protectee one to a deep friendship.
A fanfiction could be set a few years after the game. Ashley is now involved in some diplomatic work related to bioterrorism prevention, and she calls Leon in for advice. Their old feelings start to resurface as they work together again.
I really like 'Leon and the Lost Souls'. This fanfiction delves deep into Leon's past traumas and how they affect his present actions. It's a more psychological take on his character. The writing is vivid, making you feel as if you're right there with Leon in the Resident Evil world.
Maybe Naruto admires Leon's skills. For example, if Leon is a great warrior in his own world, Naruto could be inspired by his combat style and try to incorporate some of it into his own jutsu training.
One common theme is trust. Since they often find themselves in precarious situations, the question of whether they can trust each other fully is a big part. For example, in many fanfics, Leon has to decide if he can trust Ada's motives.
