Song of the Convergence (a DCU/MCU fanfiction crossover)

"Across the multiverse, the Scarlet Witch is an avatar of unbridled, reality-warping Chaos. But on Earth-0, her variant Janet Drake did the impossible: terrified of her own magic, she compressed her Chaos through sheer force of will until it froze into something completely different." Before she died, Janet locked that terrifying birthright deep inside her infant son's soul and sealed it away so he would never be hunted. She wanted him to be normal. For years, it worked. Tim Drake grew up to be a baseline human, a hyper-logical, powerless teenage vigilante operating in the shadows of Gotham City. He didn't need magic and had no clue he was homo-magi; he had calculations, contingencies, and his adoptive father, Bruce Wayne, the Batman of Gotham City. But when a cosmic Crisis seemingly claims Bruce's life, the profound trauma shatters Janet's seal. The ice cracks. Tim's dormant magic violently awakens, transforming him into a living danger to the very family and people he swore to protect. But just as he’s struggling to suppress this new power, an apocalyptic wave of entropy from a wounded alternate universe (Earth-616) crashes into his reality. Thanos has snapped his fingers, and the multiverse is breaking. To save his own world from devastation, Tim must weaponize a power he fears and pay a horrifying price. Fused with volatile multiversal energies he can barely contain, Gotham’s ultimate tactician must leave everything he’s known behind to start down a path to evolve into something… someone… capable of holding up the sky.
