Smallville: Brian Austin Green Returns as Metallo

Brian Austin Green's Metallo, the villain with the heart of Kryptonite, is returning to Smallville, TVGuide.com has confirmed.

Green first appeared in the Season 9 premiere as Metallo's alter ego, journalist John Corbin. He was killed off the following week after accidentally ripping out his Kryptonite-infused heart while trying to kill Clark Kent (Tom Welling).

At the time, Dr. Emil (Alessandro Juliani) noted that Corbin had become more machine than man, so the possibility of his survival — and Green's return — seemed possible, if not inevitable.  

Green will appear in Episode 18, which is scheduled to air in the spring.

How do you hope the writers resurrect the character?
