Screw It, I'm the Supreme King

On the surface, Alexander is a poor worker covered in grease at a Madrid factory — but in truth, he is the supreme leader of Obsidian, which controls the entire world, gifted with the "Miraculous Healer's Hands" that can bring the dead back to life and a golden ability that lets him stop a subway train with his bare hands. At the metro station, he saves Lily, the young daughter of the richest man, and is begged to revive her dying older sister — Victoria, the eldest daughter. After recovering, Victoria courts him with half her family fortune as a dowry. Meanwhile, his ex-fiancée Sofia, who had just accepted his gift of tech-park shares, cheats on him with a new lover and publicly humiliates him and his crippled old father at their wedding. In a blaze of fury, he manifests in black-and-gold glory: freezing the traitors' assets, suppressing the White Eagle elders' coup, and sending the scumbag and vile woman to the Eternal Night prison. In the end, he retires in triumph, marries the pregnant Victoria in the cathedral, and returns to an ordinary life.
