I was thinking there was actually an AMOGUS page for a second

There isnt one. Yet. But hey, we got an impostor page.

OH AWESOME

Reverse flash stomps. His speed is too much!

counterargument: what is his speed going to do against 682's plot armor

Ok, heres how i think the fight would go.

AMOGUS immediately dies of cancer.

Herobrine is depressed because his girlfriend AMOGUS died and proceeds to alt f4 from this cruel existence we call life.

Loki enhances his magic with acid, meth, super cocaine from hell, wakandan marijuana, drugs from cthulhus lair, and a lethal dose of asgardian cyanide. He dies of overdosage.

Goku Black is mistaken to be actually black, and proceeds to get gored by the police and there superior powers of racism.

Reverse Flash is traumatized when he realizes Luke Cage isint actually faster than Usain Bolt. He proceeds to kill himself by shouting that he has a bomb while in a airport

SCP 682 wins, but he dies of diabetes.

Win does not necessarily mean loose, just be unable to fight for a given time. In that case, I think Reverse Flash has got this-he can incapacitate the others before they can do the same to him.
