It’s about to get a lot more crowded in National City. In the upcoming second season of Supergirl, set to air on the CW this fall, the Man of Steel will make his grand and proper debut in the series along with several new characters, reports TVLine. Executive producer Greg Berlanti and his impressively talented band of TV cohorts will introduce Lena Luthor, Nick Farrow, The Doctor, Snapper Carr, and Det. Maggie Sawyer.

Wait, who? Let’s break it down.

Lena Luthor

The younger sister of Lex Luthor, Lena Luthor is an ESP introduced in comics in Superman’s Girl Friend Lois Lane #23 in 1961. Before DC’s world-changing Crisis on Infinite Earths in the ‘80s, Lena had no idea she was related to Lex Luthor, and it was a secret kept from her by Superman and Supergirl. She eventually found out, and, well, it was bad.

TVLine says Lena in Supergirl will be within the 25-35 age range. She knows she is Lex’s sibling and arrives in town to get away from his overbearing shadow. She’s “sexy” and “smart” and “determined to get what she wants,” but what does she want? Even I don’t know what I want.

Nick Farrow

A new series regular and a “brash leading man”, Nick Farrow will butt heads with Kara at CatCo. He’s a new character without any roots in comics (that we know of). He’s the son of a famous reporter hoping to make his own name, but his selfish and hedonistic will get in his way. You can already guess what kind of relationship he’ll have with Kara, which TVLine says it’s Kara who will help let Nick’s inner hero come out. Very elusive.

Snapper Carr

A veteran journalist who will remake CatCo’s news division by going “old school.” He is definitely different from his comic book counterpart: a groovy, leather jacket-wearing teen who hangs out with the JSA as their sidekick, debuting in The Brave and the Bold #28 in 1968. He later gains the ability to teleport, and then loses his hands. He’s a weird character.

The Doctor (Serling Rouqette?)

A new villain, she’s a “diabolical” female lead who takes over Project Cadmus using her surgical skills to implant prisoners with alien tech. A lot think she’s a new take on Serling Rouqette, a Project Cadmus geneticist who wears flashy and gaudy clothing and has the hots for Guardian. She debuted in Superboy #57.

Detective Maggie Sawyer

Oooh, here’s a fun one. Detective Maggie, who in the comics entered a relationship with Batwoman, is coming onto Supergirl as an openly-gay detective working in National City’s new Science Police, assigned to metahuman cases. She debuted in Superman #4 (Vol. 2) in April 1987 and was created by John Byrne, whose run on Superman is frequently celebrated however divisive.

Maggie Sawyer

It’d be nice if Maggie helps usher in Katherine Kane, a.k.a. Batwoman into Supergirl. It’s super unlikely, but here’s hoping.

Supergirl will return in the fall.
