So how about this one: Unicron V. Death Star.
The Death Star has the Giant Honkin' Unidirectional Space Gun (tm)(r)(c)(etc.), but Unicron eats planets for breakfast. And lunch. And afternoon tea. And dinner. And if he gets hungry around midnight he eats a planet.
A size comparison would be meaningless, becase size shift around more in the Transformers than the size of the USS Defiant. And there seems to be some debate over the exact size of the various Death Stars.
I think if Unicron got within range he'd make a snack out of the Death Star. But if the Death Star was facing the right direction and they got off a couple good shots, they might just destroy Unicron. Remove even the toughest stain. Satisfaction garanteed. Or your money back.
Cheers,
Nick
