The story, part of the 'World's Deadliest' arc, pits Batman and Superman against a mysterious enemy with ties to their shared history, while exploring the dynamics of their iconic alliance.
In "The Kandor Compromise Part One," Batman and Superman face a deadly deadline as they escort the unstable, radioactive Solomon Grundy to Slaughter Swamp, hoping to end his suffering before he detonates like a bomb.
