The new season starts on September 25. It's on Fridays now. Brian Austin Green is scheduled to make a guest appearance: He's playing Metallo in the first two episodes. [email protected] If I remember right about Metallo: He's sort of like a Terminator in that he looks like a regular human on the outside, but he's a robot on the inside. In the comics, he's extra-nasty: he's got a kryptonite heart. I never would have believed it, but he was awesome in Terminator: The Sarah Connor Chronicles. A BAG appearance is now something to look forward to. Spoilers in spoiler tags only, please.
