After being struck by a truck, John Corben (guest star Brian Austin Green) wakes up alone in an abandoned apartment as a man-machine with a Kryptonite heart. Corben realizes he now has superhuman strength and sets out to exact revenge on the Red-Blue Blur, who he perceives to be an irresponsible vigilante. Against Clark's (Tom Welling) wishes, Lois (Erica Durance) involves herself in the Red-Blue Blur's investigation, and winds up getting kidnapped by Corben.
