Comic Book Resources have posted an interview with Mike Johnson and Tim Jones (the writers of Countdown) on their forthcoming series Nero. As widely anticipated the interview confirms the series will deal with Nero's lost years in the new movie; based on scenes cut from the movie itself, the comic will include: "Robau, prison, ear damage, green blood, the Narada, explosions, astrophysics, red matter, 47 Klingon ships. And more."
The interview also reveals Spock (prime) will be a major character in the series, as will Ayel. They also list characters named Quocch and Clavell as well as "an entity whose name escapes me at the moment" and a cameo from The Motion Picture.
