Quake

Daisy Johnson is a hacktivist recruited by Phil Coulson as a consultant who turns out to be an Inhuman with the power to generate destructive vibrations, and the closest thing the show has to a second lead across all seven seasons. She takes the name Quake, leaves S.H.I.E.L.D. to work alone more than once, and ends the series rebuilding the agency on her own terms alongside Daniel Sousa.

First turns up in Agents of S.H.I.E.L.D. (Season 1).
