The chaotic energy that Loud Cloud brings to 'My Hero Academia' just screams for fics that lean into his whole 'vapor-powered' persona. I mean, the dude literally turns into a mist cloud and zips around, which isn't the flashiest power on paper, but writers have spun that into some wild stuff. Found family themes work shockingly well with him, especially since we see so little of his backstory. You can slot him into any group—the 1-A kids, a Pro Hero agency, even a villain crew—and his boisterous, supportive nature instantly creates this warm, glue-like dynamic. He's the hype man who's also secretly dealing with the pressure of having a power that's more defensive than offensive, and that contrast is pure gold for character studies.
Crossover potential is huge because his power is so visually distinct and adaptable. Imagine him in a 'One Piece' setting, navigating the Grand Line as a living logia cloud, or in a modern fantasy AU where his vapor form is some kind of elemental spirit. The real fun, though, is in crack-treated-seriously fics. Someone once wrote a story where his cloud form gets high off different atmospheric pressures and it devolved into this absurd, heartfelt thing about perception and addiction metaphors. It shouldn't have worked, but it did. His theme is less about epic battles and more about the spaces between people—how a loud presence can fill silence, how a mist can obscure but also protect. That's where the best stories live.
