My Hero Academia Crossover Fanfiction

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.

Eduardo died as a loser on an old pier, beaten to a pulp for refusing to sell his wife’s honor. Yet an ancient artifact revived him through the System of Equivalent Exchange. Eduardo was granted the power to rule the criminal underworld, but at a horrifying price: every inch of power he seized had to be paid for with fragments of his own memories. From his last ragged breaths, Eduardo built an empire. From the blood of his enemies, he forged luxury for the family he loved. But as he climbed the throne as Italy’s supreme Godfather, he realized a bitter tragedy. The wealthier his family became, the more they turned into parasites, ravenous for riches and indifferent to Eduardo’s body as it slowly hollowed out. Amid betrayals of blood and the cold crack of a sniper’s bullet, Eduardo must choose: to die as a man forgotten, or to pass his darkness into the right womb. A blood debt can be repaid, but the price of a memory lasts forever.
