The news hit the internet last week that General Zod has been cast for the Supergirl finale and that Mark Gibbon has been cast. Here is a link to Supergirl.TV's coverage: https://supergirl.tv/general-zod-is-cast-for-finale
I shouldn't be surprised by crazy responses to things these days but a portion of Supergirl critics and fans of the show had a bit of a meltdown. Would Zod be a Superman villain fighting Supergirl? Would there be room for another villain in a show which already has Cadmus and Queen Rhea?? And why take time away from a Supergirl show with someone clearly more associated with Kal?
But I think there is a simple answer. I think his role is going to be little more than a cameo.
That is because from the beginning I have said that there is going to more to come from this Legion ring so prominently displayed in the show.
And that makes me think my prediction about Mon-El is going to come true.
