Known only by a title given to her after death, the Mother of Quirks was the parent of Chikara Yotsubashi, the villain Destro. She earned the name as the first person to call Meta Abilities Quirks, a word the government later borrowed while regulating the very powers she died defending.
Little survives about how she looked, beyond long brown hair.
Her son's power arrived in an era when hostility toward the Meta-abled ran at its worst, and she loved and shielded him through all of it. She understood precisely what that discrimination cost people, and she argued for a world in which nobody was scorned for what they had been born with, holding that line through ridicule and open hatred.

Naruto vs Luffy with the twist nobody asked for: Luffy tickled Hinata on date night, and she kind of liked it. We break down the whole fight and commit to a winner....

There are no women on Namek. That isn't an oversight, it's the biology. Why we handed Piccolo the one thing his own species rules out, and why it had to be trap soul....
Destro's mother raised her child during an age of chaos, when Meta Abilities frightened the public and those who carried them were despised. Chikara was born with a power and treated as a monster for having it. She refused the framing outright: his ability, she insisted, made the boy no monster, and amounted to nothing more than one of his quirks. Change, she demanded of them, build a society where children like hers hold the same rights and standing as anyone else. Nobody listened, and an Anti-Quirk faction murdered her for saying it.
Once order returned and powers won acceptance, the authorities took up her wording, and the woman entered history as the Mother of Quirks. That acceptance came bundled with regulations restricting how such powers could be used. Chikara Yotsubashi read this as theft, his mother's language stripped of everything she had meant by it, and rebelled. Under the name Destro he founded the Meta Liberation Army to pursue what he believed she had actually wanted.
The Mother of Quirks is a posthumous title given to the mother of Chikara Yotsubashi, the villain Destro, earned because she was the first person to call Meta Abilities 'Quirks.'
She earned the name because she was the first to use the word 'Quirks' for Meta Abilities, a term the government later adopted once it began regulating those powers.
She insisted her son Chikara's ability made him no monster and amounted to nothing more than one of his quirks, and she argued for a world where children like him held the same rights as anyone else.
The Mother of Quirks was murdered by an Anti-Quirk faction after publicly demanding equal rights for people born with Meta Abilities.
Her death, and the way authorities later stripped her words of their meaning while regulating Quirks, led Chikara to found the Meta Liberation Army under the name Destro to pursue what he believed she had truly wanted.
