In a world where quirks define destiny, three unlikely heroes rise to challenge the status quo. An experimented boy discovers a device that grants him the power to transform into various alien species, each with its unique abilities. As the Omni-Hero, Izuku navigates the challenges of hero training, grappling with the responsibility that comes with wielding such diverse powers. A quirkless girl finds herself chosen by the Green Lantern Corps, and entrusted with an otherworldly power ring. With the ability to create anything her imagination conjures, Ochaco becomes a Green Lantern, bringing a new level of creativity and force to the hero scene. Another quirkless girl inherits the legendary One For All quirk, setting her on a path to redefine the legacy of her uncle, All Might. As she grapples with the immense power within, Melissa becomes a symbol of strength and determination. As these three extraordinary individuals cross paths at U.A. University, alliances are formed, and an unprecedented team of heroes takes shape. Together, they face formidable foes, uncover the secrets of their newfound powers, and challenge the very fabric of hero society.
