As a kid growing up in the 1990s, I was fascinated by pop cultural images of women and girls who possessed superhuman strength. There was Pippi Longstocking, who could lift her horse over her head. X-Men’s Rogue, who could absorb other superheroes’ powers. Eartha Brute, from “Where in the World Is Carmen Sandiego?,” a bodybuilder strong enough to steal the Empire State Building.
