Warning: this article contains spoilers for this week’s new episode of “Supergirl”!
“Welcome to Earth” was a very eventful new episode of Supergirl, with several characters making their debuts and the reveal that J’onn J’onzz isn’t the only Green Martian living on Earth. But perhaps the most intriguing reveal of all is that President Olivia Marsdin (played by Lynda Carter) is some sort of shape-shifting metahuman in disguise. But who is she really? Was she always a shape-shifter, or has the real President Marsdin been kidnapped and replaced?
It may be some time before the series answers those questions. However, we have an interesting theory. We think President Marsdin may be an iconic Superman villain in disguise. She may actually be Cyborg Superman.
