Tamaki would probably be in awe of the Avengers at first. He might try to imitate their heroic poses and grandeur, thinking it would make him seem more appealing. He could also be a bit intimidated by their power, but would quickly try to befriend them. Haruhi would be more practical. She'd probably be curious about how they got their powers and if there was any scientific explanation behind it all.
Tamaki is definitely one of the most popular. His over - the - top personality makes for great crossovers. He can be put into all sorts of situations and his reactions are always entertaining. Haruhi is also very popular. Since she's the most down - to - earth character in OHSHC, seeing her interact with characters from other universes brings a lot of contrast. Another popular character is Kyoya. His calculating nature can add an interesting element to crossovers, especially when dealing with complex or strategic situations in the crossover worlds.
The main difference is the inclusion of 'lemon' elements. Regular OHSHC fanfic may focus more on the general relationships, school life, and comedic aspects of the Ouran High School Host Club. But 'ohshc lemon fanfic' often contains more romantic or even slightly more adult - themed content, like more intense emotional and physical relationships between the characters.
For the FMA characters in the OHSHC world, you can show how they adapt to the new social norms. Edward, for instance, might initially be frustrated with the elaborate social games in OHSHC but gradually learn to play along. You can also focus on how their goals change. Maybe they start off trying to find a way back to their own world but then become invested in the problems of the OHSHC characters. For the OHSHC characters in the FMA world, their charm could be used in different ways. Tamaki could try to use his charm to negotiate with the military in FMA.
One great fanfiction could be 'The Scholarly Ohshc OC'. In this story, the original character is really into ancient books and is constantly studying them in the Ouran High School library. It has interesting interactions with the main Ohshc characters while on this book - studying journey.
Another possibility is that the Avengers end up in the OHSHC world. The Avengers would be really out of place in that high - school - like setting. Thor might be really confused by all the tea parties and formalities, while Iron Man would probably try to find a way to use the technology there, which is much less advanced than his own. Black Widow could blend in a bit better, using her espionage skills to navigate the social hierarchies of the OHSHC club.
In the end of the OHSHC manga, the characters reach significant milestones in their personal growth and the story wraps up with a mix of heartwarming and bittersweet moments. It leaves readers with a satisfying conclusion while still leaving some room for imagination.
Haruhi is practical and no - nonsense. In a crossover, she could be the voice of reason among the more outlandish characters. She might be skeptical of the whole superhero and villain situation at first. Meanwhile, Marinette from Ladybug and Cat Noir is a bit clumsy but has a big heart. Her clumsiness could be seen as endearing by the OHSHC members, and her kind heart could help her fit in with the generally good - natured Host Club. The different levels of confidence and self - awareness among the characters would create a lot of interesting interactions. For example, the self - assured Cat Noir might give some of the OHSHC members tips on how to be more confident, while also learning about their unique hosting skills.
Maybe the OC is a foreign exchange student who is lost on her first day at OHSHC. Mori comes across her and decides to help. He shows her around the school, and the OC is fascinated by Mori's calm and stoic nature. She starts to draw him in her sketchbook secretly, and when Mori finds out, he's flattered. This leads to a series of interactions where they get to know each other better and eventually fall in love.
