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.

Basically, the Decepticons and the Autobots combined are just above the total level of the Space Marines. This is not counting the Sisters of Battle, any of the Ordos (Hereticus, Malleus, Xenos), or the Imperial Guard.

Unicron would be treated as a major campaign for the Navy, but not any worse than, say, what Cadia deals with every time Abaddon comes a-knocking or what's brewing over at Orktavius.

WH40k doesn't focus on naval battles a lot, but just by the fluff, they get to some [i]rip-shit insanity[/i] in space.

Your forgetting the 13 original Primes. Each one of them is god-like

Several 40k armies throw actual gods onto the battlefield. Mostly in pieces. They wreck things.

Unicron's too small-scale in actual ability to bother the place.
