With his secret identity revealed, Superman is under attack!
Over the years, Superman has faced larger-than-life villains. Take Mongul, the intergalactic slaver who runs Warworld, a planet devoted to combat. He and Superman have clashed many times, but never with stakes so high: Mongul is looking to destroy the United Planets and create one federation under his rule, and if he has to decimate Earth in the process, so be it.
Collects Superman #20-28.
