The Rot (Anton Arcane)

The Grey (Solomon Grundy)

vs

Mangog

Herald

Kurse

pretty sure it's Harald not herald.
Anyway I'm unfalmiliar with the Rot. Other than that all of them are seemingly unkillable

Team 1.

Also, add in the Red and the Serpent.

So did the marvel guys in this fight ever have a shot at winning this fight?
Seems one-sided ..

Not that it matters, but I though SG was an avatar of the Rot..?
