Thats actually what I find funny, Sauron might be Daddy Big Bollocks in lotr, and after all that, I honestly believe that in a shared Universe he would be the scariest thing in the universe to the lanterns, but to dozens of superheroes, he would literally be a chump. Superman could solve the problem in moments as could the flash, and I can only imagine the level of crap they would give the lanterns after.

Superman: "You know, we all gave Aquaman shit but he doesnt turn into a total asshole because some half rate warlock puts on a ring."

Batman: "Wanna bet, Clark?"
