My Hero Academia Crossover Fanfiction

In a distant galaxy, where the myth of the "Ancient Humans"—a mighty race that vanished without a trace—still haunts alien civilizations, a discovery shakes the balance. Archaeologists from the conservative Caledonian Kingdom find Ethan, an Ancient Human, preserved in a cryo-capsule. Instantly, Ethan becomes the center of attention: to Caledonia, he is the incarnation of their ancient god, a symbol of divine power they can claim; to forbidden cults and the galactic mafia, he is a Satan to be destroyed or his DNA sold to the highest bidder. Amidst this chaos, Ethan, who is not divine at all, sees a golden opportunity to pursue his personal agenda. With sharp wit and charisma, Ethan skillfully plays his role as the prophesied "heir," exploiting the beliefs and fears surrounding him. He begins to gather loyal followers from various strata of Caledonian society, including curious scholars, skeptical guards, and dissatisfied nobles. Behind his divine mask, Ethan relentlessly studies the secrets of ancient Caledonian technology, searching for traces of the old human civilization that might hold the key to his species' revival. Every threat from Satan hunters or DNA traffickers he turns into a demonstration of "divine power" or an opportunity to strengthen his position. As time passes, Ethan begins to uncover the truth behind the disappearance of the Ancient Humans and how deeply Caledonia is involved in guarding those secrets. His discoveries reveal technology far beyond the current understanding of the galaxy, giving him the tools to realize his vision. With an expanding network of followers and profound knowledge, Ethan leads a revolutionary movement. He does not wish to resurrect his species as worshipped gods or feared demons, but rather as a new, independent force, ready to take their place among the stars and reshape the destiny of the galaxy.

In a galaxy governed by the Universal Ranking System, power is quantified, and destiny is dictated by an omnipotent algorithm. Every being, from the lowliest drone to the most elite warrior, is assigned a rank that determines their worth, access, and fate. For centuries, the system has maintained order but now, it’s breaking down. Kael Arvid, a disgraced pilot turned rogue hacker, lives in the shadow of his former rank. Once a rising star in the Interstellar Fleet, Kael was stripped of his status after a catastrophic mission that left him questioning the system’s integrity. When he stumbles upon a hidden code buried deep within the algorithm a code that could dismantle the entire hierarchy—he becomes the most wanted man in the galaxy. Pursued by the ruthless Ascendancy Corps, Kael must forge uneasy alliances with outcasts, rebels, and rogue AIs who have their own reasons for wanting the system destroyed. But as Kael delves deeper into the code, he uncovers a chilling truth: the system isn’t just ranking lives it’s controlling them. And it has a plan for Kael that could either save the galaxy or doom it forever. As the ranking system spirals into chaos, Kael must decide whether to destroy the algorithm, seize control of it, or transcend it entirely. In a universe where every choice is quantified, Kael’s defiance could spark a revolution—or ignite a war that will consume the stars.

In the corrupt heart of New Avalon City, a slum rat named Lucien Kane is born into a world that despises him. Orphaned, beaten, and forgotten, he grows up scavenging scraps in the gutters, dreaming of power.

Through manipulation, alliances, and sheer will, he transforms from a street urchin into a calculating criminal mastermind. His rise cuts through bloodlines, corporations, and governments — until he controls everything: drugs, politics, law enforcement, and the hearts of men. But the higher he climbs, the more enemies he creates — and the shadows he commands begin to whisper his downfall. From the gutter to the godfather… from man to myth… this is the empire of shadows.
