Mina Ashido, hero alias Pinky, is a U.A. High School Class 1-A student distinguished by her vivid pink skin, short fluffy pink hair, and curved yellow horns. Her striking yellow eyes with black sclerae and acid-resistant physiology stem from her Quirk, Acid, which lets her secrete and manipulate corrosive liquids for combat, defense, or swift movement across terrain. Her hero costume, Prism Sky, combines functionality with flair: a camouflage-patterned bodysuit, acid-resistant boots designed for sliding, and a fur-lined waistcoat, later upgraded post-graduation with streamlined boots and tactical wristbands. Outgoing and vivacious, Mina radiates infectious energy, prioritizing social bonds and playful camaraderie. She displays keen fashion intuition, channels her rhythmic prowess into combat agility, and humorously nudges peers like Ochaco Uraraka about crushes. Though academically challenged, she commits earnestly to structured guidance, such as Momo Yaoyorozu’s tutoring. Her boldness emerged early when confronting bullies in middle school, an act that galvanized Eijiro Kirishima’s heroic resolve. During the Paranormal Liberation War, she deceived Gigantomachia to shield allies, her momentary panic afterward underscoring the weight of her courage. Her Acid Quirk fuels adaptable tactics, from precise Acid Shot projectiles to defensive Acid Veil barriers. The advanced Acidman technique encases her in corrosive armor, though prolonged use drains hydration and temporarily mutes her skin’s hue. In the Final War, she strained her limits with Acidman: Alma, eroding Gigantomachia’s armor despite severe physical toll, later recovering fully. Her dance-honed reflexes and top-tier agility bolster close-quarters combat proficiency. Mina’s growth spans ranking 9th in U.A.’s Quirk Apprehension Test, earning a provisional license through rescue demonstrations, and co-organizing the Cultural Festival’s dance performance. Post-graduation, she ascends to No. 28 Pro Hero, sporting elongated horns and a polished costume. She anchors class social dynamics, bonding closely with Kirishima—whose hero path she ignited—and Denki Kaminari, her partner in event planning. Her encouragement of Ochaco’s feelings for Izuku mirrors her investment in peers’ emotional journeys. Initially proposing the alias Alien Queen, she adopted Pinky, a name mirroring her lively identity. Personal trivia includes a preference for sticky foods like natto, a vibrantly decorated dorm room, and a surname phonetically echoing the Japanese word for “acid.”
