Every /co/ related character vs. Every other /co/ related character

Who wins?

Here are the rules:

1. Each fight is 1 on 1.
2. A fight ends when one character can no longer continue. They DON'T have to be killed, but that's fine, too.
3. After a fight is over the winner regains all health, stamina, etc., as if they were starting the whole thing again at the beginning. So they won't grow tired, hungry, etc. over the duration of multiple fights.
4. Fights take place in a place that contains ALL /co/ related worlds. Characters are free to travel and to to manipulate their surroundings to the best of their cannoninical ability. And all of these worlds are physically interconncted to each other (i.e. you only have to reach the end of one, or a place in that world that would normally allow you to enter another world, and then you can cross over to any one of the other worlds).
5. Everyone fights endlessly until one character is left.
6. Match ups are arranged at random, though this shouldn't affect things either way.
