Superman stops two thugs from taking an old lady's purse in a Metropolis alleyway. The thugs and the old lady beg Superman not to kill them. He tries to get them to relax, but they are suddenly destroyed by a sonic blast. Damage is everywhere. Superman decides to follow the old woman and sees her going into the "Museum of Dead Villains," which displays a giant poster of Superman titled "Superman's Day of Wrath." Superman enters the museum, and reads a placard that says Superman killed all of his opponents in three weeks starting on April 15, 1998. Superman walks through the museum, seeing the skeleton of Mr. Mxyzptlk encased in an alien crystal . The Prankster exhibit tells of how he was dropped from space and disintegrated in the atmosphere. Metallo's brain was vaporized in it's metal skull by Superman's heat vision. Brainiac was killed by a blow to the head in his failed attempt to harness Mr. Mxyzptlk's powers. The Joker was placed on a cell on the moon with almost no food, water, or air. He died in three days. Darkseid took the longest to defeat, but Superman killed him, destroying half of Apokolips as well. Superman spies someone hiding in the museum and confronts him. The man explains that Lex Luthor funded the museum and tells him that Superman left Earth after killing his enemies. He walks out of the museum and runs into Lois, who is confined to a wheelchair since Superman left her under a pile of rubble in the Joker's lair. Attempting to scan her with his x-ray vision, Superman accidentally incinerates her with his heat vision! The crowds go nuts at this, and he has to blow them back with his super-breath. Superman goes to Lexcorp and finds Luthor there. However, Luthor's things are being moved out; Superman had bankrupted him. Luthor warns that he's given Superman's enemy exactly what he'll need to kill Superman. Jimmy Olsen's signal watch buzzes throughout the office, and Superman is about to leave help him when Luthor rips off his fake face to reveal Jimmy Olsen underneath! An angry Jimmy opens a box of green kryptonite, aiming the radiation directly at Superman.; The Newsboy Legion celebrates the Guardian's recovery. Gabby reiterates that Angry Charlie is real, and we see the helpful creature looking in from an air vent. They reminesce over the Guardians old helmet, but they are soon told that visiting hours are over. Tom tells Guardian that when he's well, they want him to go into the unexplored caverns to find what's been raiding their supplies. Angry Charlie steals an end table through the vent and takes it to a lab, where he eats it. He looks at a photograph captioned "Tommy, Dabney & Me - My new (cloned) body!" He remembers a scene of Dabney Donovan being threatened with his project being shut down. He injects one of his monkey subjects with something and creates Angry Charlie. When Charlie awakens, he sees what he's become and what the other monkeys have become. Shino and Anthony later walk into the lab to find that it's been destroyed. Deep in the airvents, Angry Charlie continues to look at the photograph.
