cancer fanfiction

In a dying universe, a supernatural being chooses Atlas to save the multiverse from collapse. The threat comes from the increasing number of heroes being reincarnated into other universes. Atlas is tasked with hunting down these heroes, who have been granted powerful boons that make them nearly invincible. Atlas must rely on his wit and surprise to take down these powerful foes, and each new universe he enters presents a unique challenge with a different power system to master. With only his experience to aid him, Atlas begins his mission to save the multiverse. Will he succeed, or will the heroes prove too powerful to defeat? This story will feature dynamic character development, with a focus on character interactions rather than solely on the whole hero buisness. The Mc will also not always get what he wants or needs. He will only be able to fight the Hero with abilities he can reasonably get, and naturally, each universe he goes through will give him more of an advantage compared to the common people, but the real Heroes will always have something like classical fanfiction heroes, which means powers like Devil Fruits, Haki,  Ninjutusus, systems, cultivation, powerful bloodlines, magic, Marvel or DC powers, an inbuilt AI or other weird but powerful abilities.  P.S.: I don't own the rights to most universes that will be explored.
