Koa Fizzaki

In the bustling corridors of U.A. High School, Koa Fizzaki stands out as a quiet yet profoundly observant presence. Her hero name, Reflexia, speaks to her extraordinary power: Echo Reflex, a Quirk that lets her perceive and mirror movements, energy, and attacks by reading their ‘echo’—a faint residual energy left in the air. With eyes that glow a soft blue when she activates her power, Koa becomes a master of anticipation, predicting and countering her opponents’ actions with precision. Despite her reserved nature, she possesses an unyielding instinct to protect those she cares about, often putting herself in harm’s way to shield her allies from danger. Her hero costume, a dark-blue bodysuit with glowing lines and a visor that enhances her ‘echo vision,’ allows her to navigate even the darkest environments with ease. Koa’s empathetic core shines through in her interactions with classmates, where she uses her keen intellect and strategic mind to devise plans that leverage her teammates’ strengths. Whether she’s replicating Bakugo’s explosive blasts, mirroring Uraraka’s zero-gravity maneuvers, or observing and perfecting her close combat reflexes by mimicking Deku’s punch rhythm, Koa Fizzaki proves herself to be a versatile and formidable hero. Her journey is one of growth, as she learns to balance her analytical nature with the emotional connections that make her a true hero.
