DC Comics collects two fast-paced tales by Grant Morrison (BATMAN, FINAL CRISIS) and Mark Millar (CIVIL WAR, FANTASTIC FOUR, THE ULTIMATES), two of comics' greatest storytellers. First, in the story "Human Race," a powerful alien entity called Krakkl amuses himself by pitting the fastest beings in the universe against one another in races through space and time, with the racers' homeworlds at stake. Then, a powerful being called Black Flash arrives on the scene - and wherever he appears, a super-speedster dies!

Originally published in single magazine form in The Flash 136-141, Secret origins 50.
