Emi Fukukado, the Pro Hero Ms. Joke, teaches second-year hero students at Ketsubutsu Academy High School. Born in Kumamoto Prefecture, she operates in a society where most possess superhuman Quirks. Her Quirk, "Outburst," forcibly induces intense, incapacitating laughter in targets, impairing cognitive functions and motor skills. This ability defines her crime-fighting style, typically subduing opponents through distraction before employing hand-to-hand combat. She possesses an athletic build with noticeable muscular definition, particularly in her arms, and stands at 166 cm (5'5"). Her sea-green or seafoam-colored hair reaches past her shoulders, featuring a short fringe often obscured by her signature orange bandana. She has dark green eyes with bright pupils and a constant, broad smile. Her hero costume consists of a sleeveless navy blue top with a high collar, puffed shorts with green and orange/yellow vertical stripes, a black corset adorned with yellow smiley-face pins, a white V-shaped belt, and padded yellow gloves with golden knuckle plates extending into orange-striped arm tubes topped with thick metal wrist guards. She occasionally wears a white respirator mask with smiley-face protrusions during hero work. Her personality is defined by relentless cheerfulness, outgoing humor, and playful teasing. She maintains a jovial demeanor even in serious situations, using jokes and banter to diffuse tension. She demonstrates professional dedication and perceptiveness regarding heroics and education, showing genuine concern for her students' potential and well-being. She often criticizes perceived elitism from rival institutions like U.A. High School, particularly after U.A. overlooked Hitoshi Shinso's capabilities during the Sports Festival. Her interactions with U.A. faculty member Shota Aizawa (Eraser Head) involve persistent, unabashed flirting, including repeated marriage proposals, which he consistently rejects. Despite this, she respects his abilities; their history includes collaboration during their early hero careers when their agencies operated in proximity. She views their relationship as potentially romantic, though this remains unreciprocated and ambiguous. Her chronological appearances begin with attending the U.A. Sports Festival as an observer, where she vocalized disapproval of Shinso's placement in General Studies. Later, during the Provisional Hero License Exam, she accompanied her Ketsubutsu students and re-engaged Aizawa, teasing him about their past while introducing the rival classes. She expressed disapproval when Aizawa implied U.A.'s superiority and questioned whether he had adequately prepared his students for being targeted during the exam due to their publicized Quirks. Months afterward, she participated in the large-scale raid on the Paranormal Liberation Front's stronghold at Gunga Mountain Villa, assisting in breaching the villa and arresting villains as part of the hero task force, facing significant resistance. Her character development remains consistent in portraying a balance of levity and competence. She advocates for non-elitist hero education and student potential, contrasting her comedic exterior with moments of tactical insight during missions. Her backstory reveals a history of agency work alongside Aizawa, forming a foundation for their ongoing dynamic. In later timelines, she continues teaching while sporadically undertaking hero duties, exploring activities like boxing to maintain combat readiness. Her primary motivations remain mentoring future heroes and maintaining her distinctive, laughter-focused approach to heroism.
