Green Lantern v. Sinestro – Sinestro is a corrupt renegade from the GL corp, which means they’re more or less evenly matched and each understands the other’s outlook. Rather like Obi-Wan Kenobi and Darth Vader.

Golden Age Green Lantern vs Soloman Grundy.
Ring-slinger vs man-monster.

No, that’s not it.
The closest I can find to what I think I saw is this right here Imagine that, only with a black backround.

Luke v Darth

Arnold v Predator

Ripley v Alien Mother

Dang. Missed edit window.

Aeon Flux v Trevor Goodchild

William Munny/Little Bill Daggett

Errmmm . . . This is a slashfic thread, right?

Sarah Conner vs Killer Robots from the Future/SkyNet

The machines have the edge in every way–they’re more durable, stronger, and more determined than is humanly possible. And yet, Sarah’s human refusal to accept the role of weak victim means she’s the unbeatable one–The robots don’t want to face John Connor, but Sarah is the one that should really scare them.

Londo and Morden.

Vader and Luke.

John Crichton and Scorpius (Farscape)
David Xanatos and Goliath (Gargoyles)
