Who wins?

Literally every character, show, comics, even that one mobile game that has random characters in it Or Discord?

Rules for the matchup: absolutely no win conditions (so no friendship, nor elements of harmony or grogar's bell), no Cosmos (comic character) and no using any sort of pre-emptive connections discord has with any characters as an emotional thing, so Discord is going all out, and all characters are in their prime

I'm personally saying Discord, since he does sweep the floor with all the canonfodder characters, and even with the combined force of every other character I doubt they can actually keep him down, although I think Pinkie, Celestia and Twilight make pose a small challenge
