While it doesn't seem entirely necessary, the next DC Comics adaptation heading to the small screen is Krypton, a show which will be set on Superman's home planet years before he was born (and it, you know, exploded). Clearly inspired by the success of Gotham and the positive response to the scenes set on that world in Man of Steel, it's actually easy enough to understand why they're moving forward with the show. Now, a list of the characters have been revealed, and it sounds like an interesting mixture. 

SEG-EL – described as athletic, quietly confident, and in his 20s, an older version of this character appeared in Starman #51 alongside his son Jor-El (Superman's father). 

LYTA ZOD – a beautiful twentysomething, Lyta is a reluctant warrior and has a familial tie to eventual Superman villain General Zod.

VAL-EL – The genius grandfather of Seg, he defied death by entering the Phantom Zone and believes in space exploration.

ALURA ZOD – Lyta's mother, she too
