What if the new enemy faction were actually called "The Children"? They should be actual infants. Considering how much weaker some of the weapon classes are now it would be appropriate. They attack in swarms and when you shoot them they are ripped to pieces but the re-enforcements can fuse the remains of their fallen comrades into their own bodies becoming like that blob baby Tetsuo at the end of Akira. You can pay Luke Smith $14.99 for an emote where you yell "Tetsuo!!!!".

Their god should look suspiciously like Michael Jackson and call the guardians "scurrilous lairs". He dances and grabs his alleged nuts to activate his super.
