Cthulhu wins

And no it won’t end in a draw

Um Cthulhu dos have combat experience he’s fight other H.P. lovecraft gods as he sleeps and discord is the one who can’t fight he’s become to soft with his time in pony vill and if fluttershy is in danger then maybe just maybe he mite fight but he’s still going to loss and Cthulhu can indeed ultr reality and cos true chaos just look up what chaos means and you will see just who Mighty The grate old ones are and yes Cthulhu has siblings

well from what i read about Cthulhu all the stuff he’s done, all of it is just massive hyperbole, in reality he spends most of his time sleeping and when he actually wakes up, he usually mindfucks the ever-loving crap out of everything so if he met the nigh-omnipotent chaos god known as discord, discord might be to fight off Cthulhu’s insanity trick while using his magic to fuck shit up, messing with Cthulhu, also it doesn’t really help him all that much that he doesn’t have any combat experience, since he spends all his time sleeping and is currently fighting a nigh-omnipotent chaos god, and to top it all off Cthulhu despite being a deity has a very pathetic healing factor since the first time he showed up a steamboat cut him in half.

However it is said that Discord is like Q and Q is also omnipotent. So even then it would probably end in a draw

Discord is basically an immature version of Q and since Q are omnipotent Cthulu is screwed.

@LordofPride  
Um, yeah. I’m pretty sure Nyarlathotep would crush Discord like a gnat. Sure, Discord has the ability to bend reality at will, but he’s at best interplanetary level in terms of power. From what I heard, Nyarlathotep is a vastly powerful cosmic entity that extends to a MULTIVERSAL level; meaning he can casually wipe out entire universes.
 
I can also imagine Discord making fun of Azathoth. Mocking the fact that he has infinite power but very low intelligence.

@Background Pony #580E  
Not to mention Nyarlathotep is basically Azathoth’s will and soul, so he’s pretty much omnipotent.

@LordofPride  
You do realize if Azathoth were to wake up, all of reality would be wiped clean right?

Cthuhu nothing, Discord against Nyarlathotep or Azathoth would be a fairer fight,

@Questionmarktarius  
Possibly both.

The real question is:  
Fight or Make Out?

add Bobobo to this and neither Cthulhu or Discord would be able to know what the heck is going on :P
