In the sitcom’s twelve-year run, The Big Bang Theory brought nerd culture into millions of homes on a weekly basis.

But when they did, they bit off more than they could handle when they decided to step into Power Girl’s life.

Power Girl, aka Kara Zor-El, aka Karen Starr, is a perfect representation of the wide world of DC’s multiverse.
