While traveling the Omniverse alone, Ben Tennyson stumbles upon a parallel Earth unlike any he's seen before...a world where nearly everyone is born with powers called Quirks. Curious, he investigates from the shadows, only to draw attention after repeatedly saving civilians in strange, inhuman forms. His actions lead to a confrontation with U.A. High's Shota Aizawa. Instead of exposing him, a risky decision is made: forged documents, a false quirk, and a place at U.A. University.

Izuku Midoriya spent his whole life being told he would never be a hero. Born quirkless in a world built on power, he endured years of ridicule, beatings, and shattered dreams. But everything changes the day he throws himself into danger to save an elderly man trapped beneath a collapsing subway station. The "old man" is no ordinary citizen. He is the wizard Shazam, ancient guardian of magical forces older than quirks themselves. Impressed by Izuku's selfless courage, the wizard chooses him to become his next champion. With a single word - "Shazam" - a bolt of divine lightning transforms Izuku into an adult hero imbued with the power of legends: the Stamina of Atlas, Strength of Hercules, Wisdom of Solomon, Power of Zeus, Courage of Achilles, and Speed of Mercury. Even without a quirk, Izuku Midoriya was always meant to be a hero.

Izuku Midoriya was powerless. Mocked, beaten, and cast aside by a world that valued strength above all, he still held onto his dream of being a hero. Even as reality crushed him, Izuku refused to let go of hope. But fate has a different plan. One night, after another humiliating encounter with Katsuki and his bullies, Izuku stumbles upon a strange rift-an unnatural tear in space, pulsing with black energy. From it emerges a man cloaked in shadow and presence: Ashborn, the Shadow Monarch. Ashborn looks into Izuku's eyes and sees something familiar-not power, but potential. A will that refuses to break. With his time running out, Ashborn offers the boy a choice: remain powerless... or inherit a throne of darkness. Izuku accepts.

Centuries after Goku's wish, Majin Buu's spirit is reborn on Universe 6's Earth - a world now filled with Quirks. Born with pink skin, red eyes, and a tail, Izuku Midoriya carries the power of the ancient Majin within him. Once feared by many, he must learn to control his chaotic strength and prove that even a being born from destruction can become a true hero.

When a dying alien transfers its armor to Izuku Midoriya, he becomes the new host of Tech Jacket 49-C-a weapon of galactic power. With the cold, tactical AI Helix as his guide, Izuku finally has the strength to be a hero.
