Supergirl is winding down its second season - and first in its new home on The CW - with more and more news breaking about guest stars who will be appearing on the remaining season 2 episodes. It was recently indicated that Teri Hatcher's character may be appearing earlier than fans initially expected, while Darren Criss as the Music Meister will be showing up during The Flash/Supergirl musical crossover episode this month.

The Flash recently tapped David Dastmalchian to play a villain in one of their upcoming episodes. Dastmalchian plays Dwight Pollard, a morgue night manager with ties to Jerome on the TV show Gotham. It seems that Supergirl has similar casting practices and is open to casting actors that have already debuted in other comic book-based TV shows.

EW is confirming that Rahul Kohli (iZombie), has been cast as Jack Spheer in Supergirl season 2. His character will be a charismatic tech genius who has spent years working on a device to eradicate all illnesses. If it works, his device has the potential to change the world - but seeing as the character becomes a supervillain in the world of DC Comics, that seems unlikely to happen. Either way, Kohli is happy to appear on another show at The CW, as he mentioned in his statement about the news:

“I’m so excited to be working on Supergirl starring as Jack Spheer. It’s given me the chance to continue my relationship with The CW as well as fulfill my goal of meeting a Kryptonian.”

Jack Spheer is a character that appears in DC Comics as the villain Biomax. He gains the power of mind control after his device malfunctioned. On Supergirl, his invention will bring him to National City to share his technology with members of the press that include: Kara Danvers (Melissa Benoist), and Snapper Carr (Ian Gomez). When he makes front page news, Spheer's appearance will bring up feelings in his former love-interest Lena Luthor (Katie McGrath). His character is slated to appear in the episode 'Ace Reporter'.

As with many of the villains that are tapped to appear on The CW DCTV shows, Jack Spheer has a silly name and a very convenient reason to not like the most charismatic character on Supergirl. In spite of that, Kohli does consistently great work on iZombie, which has a pretty silly conceit in and of itself, so he can probably handle a one or two episode arc that Supergirl has planned for him. Given the fact that he has pre-existing ties to Lena Luthor it also seems possible that Spheer will wind up working with Cadmus - the big bad of the second season.

Conversely, one of the least interesting things about this incarnation of Supergirl is that her alter-ego Kara Danvers is a reporter. This was a change that came at the beginning of this second season, when the show was in a state of upheaval. It's a move to try and make her more like her more famous cousin, but as fans have seen repeatedly this season, Kara isn't a particularly good reporter. She consistently lets her personal feelings get in the way, jumps to conclusions and acts unprofessionally toward her bosses. If 'Ace Reporter' is going to focus more on that aspect of her life, then it gives the show a chance to address those related complaints from fans head-on.
