Okay. I didn't get the 'exterminatus' thing. Too bad it wouldn't work ... cuz Unicron is a god.

Ah... put simply, Exterminatus is the complete annihilation of a planet. It comes in many, many flavors, but my most favorite one is the one where a fleet of battleships bigger than Metroplex open fire on the planet until they effectively split it in half at the core.

Unicron might be able to win a skirmish against one or two Exterminatus-class Imperial ships, which is why they often come in [i]dozens.[/i] The Imperium has plenty of resources to throw away, and that's not even considering the [i]other[/i] parties that might want a piece of Unicron.

Considering he doesn't just tear the ships apart by whatever his red beam of death is. He eat's planets. [url=https://www.youtube.com/watch?v=oO81U365FgU]Your argument is invalid.[/url]

So they stop playing nice and actually focus the Imperial Navy. If it's a slugging match, the Imperium [i]wins[/i]. They've got too many ships, and something that threatening would have them actually focus the insanity that is its disparate forces. You're trying to take on a sci-fi Empire that inhabits billions of worlds, many of which have far greater populations than modern Earth, with a single planet-sized thing. It's a losing battle.
