Mina's horns in 'My Hero Academia' are fascinating because they aren't just for show—they're actually a key part of her Quirk, 'Acid.' While the series doesn't dive super deep into their mechanics, it's implied they help her regulate or focus her acid production. I love how the design ties into her power visually; it's like her body evolved to handle her ability safely. Her horns might even act as natural 'nozzles' for directing the acid, given how precisely she can control its flow. It's those subtle world-building details that make 'MHA' so rewarding to analyze.
That said, I wish we got more lore about mutant-type Quirks like hers. Do the horns grow back if damaged? Are they sensitive? The fandom's full of cool theories, like some suggesting they might store excess acid or even sense chemical changes in the air. Until Horikoshi gives us more info, I'll keep obsessing over tiny animation frames for clues—like how her horns seem to glow faintly when she uses her Quirk at full power. Small things like that make her design one of my favorites in the series.
