Zom and King of Tears Vs. Shuma Gorath and Nekron

Some of the most powerful demons in comicdom. 
Neutral realm. 

Which team comes out on top?

Team 2 . Unless someone provides more information about King of Tears .

Team 2 wins

King of Tears doesn't have a lot of feats, assuming it's the one who "skinned" The Spectre. 
 
Has to be the first time though, solely due to Zom.

Team 2
