In an interview with Comic Book Resources, Supergirl producer Andrew Kreisberg confirmed that fans will get to see the Big Bad for Season 3 in the Season 2 finale. While no specific character was named, Mark Gibbon was recently cast as #GeneralZod. However, speculation is that Zod will not be the reveal that Kreisberg was mentioning.
“We will get a glimpse of the Season 3 villain in the finale, which we’re also excited about.”
The finale will also feature the return of Callista Flockhart as Cat Grant and Lynda Carter as President Marston. So, who could Kreisberg have been referring to?
1. General Zod
General Zod has been a foil for Superman for decades. First appearing in Adventure Comics #283, Zod was a military strategist from Krypton who resided in the Phantom Zone when the planet blew up. After years in limbo, He was freed with two of his underlings who also gained the powers of Superman by absorbing rays from the yellow sun. Given no other option and being severely outmatched, the Man of Steel was forced to break his rule about killing to dispatch the villains.
While there is no reason to believe that the Maid of Might couldn't take on General Zod for a season-long arc, Zod is known to be a #Superman villain. They have a history and, without the connection of Jor El, it seems less likely that Zod would be a Big Bad in Supergirl. Plus, Supergirl runs the risk of villain familiarity that has plagued The Flash for the last couple of seasons. With Kryptonians in Season 1 and Daxamites (essentially Kryptonians) in Season 2, the showrunners are probably looking to introduce a bit of variety. Kreisberg has also gone on to describe what Zod will look like and teased his appearance, so it is unlikely that he is a future Big Bad.
2. White Martians
Earlier in the season, Lynda Carter's President Marston was revealed to be an alien. More specifically, a white Martian — a race hell bent on annihilating any race they deem inferior. J'onn J'onzz, a green Martian, knows all too well of their cruelty, having lost his family to them, even influencing M'gann, another white Martian who defected to Earth and is currently back on Mars leading a resistance.
White Martians would be an interesting twist for the next season. The show would still have a villain powerful enough to face the Girl of Steel as well as the Martian Manhunter, Mon-El and even Superman. Without knowing the events of the season finale, it's hard to speculate, but if President Marston doesn't make it out alive, that's easily a reason for the white Martians to come knocking on Earth's (much weaker) door.
3. The Legion Of Superheroes
The Legion of Superheroes have always been portrayed as heroes in the comics and there's no reason to think they won't be portrayed that way in the show — eventually. The team of the future has been teased in Supergirl (and Flash) for quite some time now, and Mon-El is a famous member. When Mon-El first premiered in Superboy #89, he was exposed to lead, which is poison to Daxamites much like kryptonite to Superman. Superboy gives him an experimental serum to keep him from dying and sends him to the Phantom Zone, where he stayed until the 31st century. The Legion found him and cured him of his poisoning. He then became Valor and joined the team.
If Mon-El gets lead poisoning (like when he was shot in Episode 7, "The Darkest Place") Team Supergirl could follow suit with the comics and put him in suspended animation until a cure can be found. They bring him out, cure him, and deliver him back to our time where they find a crude, barbaric civilization that needs their attention. Supergirl will, of course, stop them and inspire them the way her cousin did originally. Expect some friction when she falls for Brainiac 5 along the way.
The confirmation of a lead-in to Season 3 is par for the course for The CW. Recently, they confirmed that The Flash would have a shocking ending that would lead into Season 4. Perhaps we should only concern ourselves with the current season. With villains like Cadmus, Cyborg Superman, White Martian President Marston, Jeremiah Danvers, Mon-El's mother Rhea, Zod and possibly Lena Luthor, Supergirl certainly has her hands full. Fortunately, she'll have help from her cousin, the Man of Steel.
Supergirl flies onto our televisions on Mondays on the CW. Here's a teaser for the next action-packed episode, entitled "Alex":
