- —Stein to his SWAT team[src]
Captain Stein is a police captain of the Star City Police Department. He has little tolerance for vigilantes; to the point of being extremely violent and unstable.
Stein's fate is unknown, but he was likely suspended or demoted from his position, if not fired from his department by the police board, for his rogue actions that resulted in the death of Frank Bertinelli (albeit unintentionally).
