For the Man Who Has Everything/Nightmare Fuel


 * In the adaptation, the effects of the Black Mercy are kinda scary, you have to see what you don't want in order for you to escape, that has to be bad, but what was one of the scariest parts was when the Black Mercy was on Mongul, while we never see what's going on in Mongul's head, the sounds you hear in his head (screaming, destruction...) are disturbing.
 * Well you'd think Nothing Is Scarier... Until you realize that A) the Black Mercy shows you your perfect life, and B) Mongul is the one that created War World. So all of those horrible noises, as expected, are most likely him overseeing an eternal war on the entire known universe... And winning. Gruesomely.
