Supergirl Season 2 Finale: Air Date Set, Plus the Debut of a Major Big Bad

The Supergirl Season 2 finale will air Monday, May 22 at 8:00 PM on the CW.

Expect action, drama, pathos - and General Zod! Smallville and Man of Steel actor Mark Gibbon has been cast as the brutal Kryptonian dictator. This is great for the show, which is set to wrap it's second season as a nearly flawless show - the only thing notably missing is a genuinely threatening, mission-defining antagonist.

General Zod has been the perfect villain for the Super-family for decades, and Superman veteran Gibbon is a spot-on casting. His appearance on the season finale should set the show up for a third season with greater tension, and higher stakes.

And the finale will be a family affair as well - Tyler Hoechlin's Superman will make an appearance as well, meaning we'll be seeing a lot of Kryptonians - quite possibly, the most we'll see on a single episode until Syfy's Krypton.
