Superman has lost it, but it isn’t his fault. The Joker altered his mind and caused him to believe that Lois was in fact Doomsday. Superman killed her and his son and if anything was cause for a superhero to go off the rails that was probably it. It resulted in Superman taking control of the planet, making sure that nobody ever steps out of line again. Superheroes who defy him are dealt with, while some villains aid him. Batman, as expected, has his own plans. The culmination of the above is some of DC’s finest characters battling it out in a 2D fighter from NetherRealm Studios.
