We’ve only got three more episodes to go before Supergirl wraps up its sophomore season on the CW with some amazing guest stars and the arrival of an iconic Superman baddie.

As some of you may already know, Tyler Hoechlin will be flying back to National City as the Man of Steel to lend a helping hand to his cousin Kara (Melissa Benoist). But he won’t be the only familiar face returning for the finale. Calista Flockhart will be back as Cat Grant for the final two episodes, and so will Sharon Leal as M’Gann and Lynda Carter as POTUS.

That’s what Andrew Kreisberg revealed during a recent interview with the good folks at Comic Book Resources:

We are bringing back people we’ve had all season. We have Calista Flockhart coming back. In the last two episodes, we have Lynda Carter returning as the President, Sharon Leal is coming back as M’gann. Obviously, there’s Tyler as Superman. These are some of the biggest episodes we’ve ever done. We’re so proud of Teri Hatcher, and so amazed she’s on our show and killing it as Rhea. There is a feature film quality finale, with huge guest stars, stunts and visual effects. We will get a glimpse of the Season 3 villain in the finale, which we’re also excited about.

So who could that Season 3 villain be? My money is on General Zod (although it could be someone else entirely), played by Mark Gibbon. Here’s what Kreisberg had to say about Zod’s arrival to Earth:

I don’t really want to say too much about Zod. How and why it happens is a fun surprise. As far as his costume is concerned, we took a page out of the older, Nazi uniform that he used to wear, which was very cool. That name instantly means something to fans of Superman and Supergirl. It’s a bit of a cameo surprise in the episode.

As for Clark’s role in the finale titled “Nevertheless, She Persisted,” Kreisberg hinted that his presence will be "incredibly crucial” to the story, which will see the Girl of Steel and the rest of the DEO going up against Rhea (Teri Hatcher), who's got a mysterious (and no doubt nefarious) master plan that includes Kara, her son Mon-El (Chris Wood) and new business partner Lena Luthor (Katie McGrath):

He’s incredibly crucial. I love Tyler in the part — he’s so good. It’s a bit of a different interpretation of Superman than you’ve seen. In our show, Superman has been [a superhero] for a decade, and he’s pretty comfortable with being Superman. A lot of interpretations are of him getting his start, at the beginning. For us, he’s so comfortable in the role, but the show is called “Supergirl,” so our Superman is here in service of Supergirl. He’s her family. He’s her conscience. He’s her mentor. There’s also some very cool scenes between the two of them.

Bring. It. On. In the meanwhile, check out this extended trailer for next week’s episode of Supergirl: “City of Lost Children,” airing on Monday.
