what would happen in a battle with the emporer and all 20 primarchs(pre heresy)
vs.gork n' mork vs.all 4 chaos gods vs. the c'tan vs.the hive mind vs.kaine ,phoenix lords,laughing gods ect...for eldar vs.whatevar the tau have to offer to this fight. please tell me your opinion on how it would go and what/who i left out.
This is pretty ridiculous, but I respect you for your over the top thinking. Warhammer 40K is all about taking an idea and cranking it up to 11.
If we're assuming that all these forces could combat one another on a real, tangible level, it'd go like this:
First off, if the Emperor was in fit condition and on good terms with all twenty primarchs humanity would be able to put up a decent fight. They have strength in numbers, but sadly that wouldn't be much in the face of these odds. The Emperor's pretty beast, but he falls quite a bit short of a chaos god, and neither 20 nor 200 primarchs at his side will make a difference. The lot of them might
be a match for, say, the void dragon, but suggesting they'd come out of this match-up victorious is laughable.
Gork and Mork are powerful enough to be more or less indestructible, even to other gods. This doesn't mean they'd win, mind. The chaos gods and maybe the c'tan would be able to take them out of the fight, if not necessarily put them down permenantly.
The hive mind is not an entity. It can't participate in a fight.
Khaine is a broken god and even with his considerable power he'd be no match for most of the combatants. If he were back in his glory days he'd be able to pummel Nightbringer at the least in addition to the other C'tan. I have no idea how powerful Cegorach is in relation to the other Eldar gods, nor do I know where the phoenix lords stand. I assume they're weaker than the primarchs?
The Tau have no tangible gods that I know of. A weak warp presence will do that.
The C'tan will be in the running for some time. Between the raw power of the Void Dragon and Nightbringer as well as the manipulation of the Deciever, the C'tan have decent firepower and tactics in their favor. However, their power pales in comparison to the chaos gods.
If their expressed intent was the destruction of the listed opposition, and they were allowed to bear their full power, the chaos gods would claim an easy victory. They'd slaught the C'tan, murder the Emperor and his children, disperse Kaine's avatar, and beat down Gork and Mork until interest took them elsewhere. Nothing in the series compares to the might of the chaos gods.
All in all, I say it goes something like this: Chaos>C'tan> Gork and Mork> Emperor> Eldar with the Tau and Tyranids not being in the running.
