American comic book mutants: Magneto said I'm too extreme.

Transmigrated into the world of American comics, Charlotte awakens in an underground facility, destined to be studied as a newly manifested mutant. In this grim reality, mutants are treated with less dignity than animals, subjected to brutal human experimentation, brainwashing, and invasive biopsies—experiences so harrowing they make death seem like a mercy. Desperate for escape, Charlotte’s fortunes change when a system activates at the critical moment, granting her the "Accelerator" template as a starting reward. With the power of vector manipulation at her command, she holds absolute control over her surroundings. This is merely the beginning of her rise. Wielding immense influence, she drives a radical de-urbanization across America, shocking even Magneto, the renowned hardliner among mutants. As her methods grow increasingly ruthless, the consensus becomes clear: Charlotte is far too extreme.
