Someone recently mentioned Jane Thor in a post, and it got me thinking about how now we have female characters who are top tier in power level. But that hasn't always been the case. In the 60's we had Sue Storm who didn't yet have force field powers and Jean Grey with modest psi powers, but they were the weakest members of their groups. Come the 70's, they and other female characters became more powerful.
I was wondering, who's the first female Marvel character to have top tier power levels? Would it be Jean Grey as Phoenix? Who's the first female DC character to have top tier power levels? I suppose Supergirl or any kryptonian would count.
Battle of the Sexes:
Captain Marvel (Carol)
Jean Grey as Phoenix
Thing and Moondragon to the lists?
