Here's a look at tonight's sci-fi TV:
Smallville, "Upgrade" – Fan favorite Brian Austin Green returns as bionic baddie Metallo in an episode that sees Lois getting kidnapped (again!) and Clark teaming up with Zod. Rumor has it that red kryptonite is messing with Supermanboy's senses in tonight's new ep. (8 p.m. ET on The CW)
Stargate Universe, "Faith" – In what sounds like a move from the Battlestar playbook, the Destiny crewmembers consider ditching their spaceship digs to settle on a cozy star orbited by one planet. (9 p.m. ET on Syfy)
Also new tonight:
- Batman: The Brave and the Bold (7:30 p.m. ET on Cartoon Network)
