One of the downsides to hanging out with Superman is that you may occasionally get hit on by a supervillain. On 'Smallville' (Fri., 8PM ET on The CW), Lois Lane (Erica Durance) gets a taste of this when Metallo (Brian Austin Green) puts the moves on her. Sure, he's cute. But he's a cyborg with a Kryptonite-powered heart who hates Superman -- not really the best catch.

Watch the video after the jump.

(S09E17) Five episodes left in this ninth season, so General Zod needs to start putting together whatever his endgame plan is going to be. Steps were definitely taken toward that this week, but first we got the return of one of Superman's deadliest foes: Metallo.

It's always nice to see Brian Austin Green, and he's actually quite effective in this role. I was a little disappointed in how quickly they were able to re-establish his character in whatever way they needed him for this week, but I'll forgive it because it was so much fun seeing almost everyone else turned on their ears.

Checkmate and The Wall took a break from intimidating everyone and pushing Tess around, which freed Tess up to make an unexpected alliance. Also missing from the fun was Green Arrow, but there was plenty of action without them.

(S09E02) And just like that, Clark Kent returned from the dead. And all it took was the impossibly astute observation of a homicidal cyborg.

It's a shame that Brian Austin Green's John Corben, aka Metallo, was relegated to freak of the week status. Seeing him stick around to possibly become Clark's rival at the Planet and on the mean streets of Metropolis would have been fun.

As he proved during his stint on TSCC, Green's a talented guy who feels right at home kicking ass on a sci-fi show. He did a fine job here, even if the material he was given would make a Saturday morning cartoon script read like high art. But sadly, this ep was less about Metallo and more about Clark learning that dumping his friends and skulking on rooftops probably won't make him a better hero. (More on that in a sec.)

Well, the corpse has turned cold for only a second but already Brian Austin Green has gotten more work since the cancellation of Terminator: The Sarah Connor Chronicles. Green's scheduled to play the villain Metallo for at least two upcoming episodes of Smallville.

The man who was fighting cyborgs in a previous show is now playing one. Green must be a fan of sci-fi and comic books and the like since his recent roles reflect that.

I highly suspect that the upcoming season of Smallville is its last, particularly given its new Friday night timeslot. The creators have already thrown a ton of villains at Clark that in theory he shouldn't be meeting until he becomes Superman.

In the comics, Metallo has a Kryptonite heart which powers his cybernetic body. Assuming the show continues that character trait (and it likely would), wouldn't anybody in proximity of Metallo suddenly gain super powers? I'm just saying.
