As a New God, Darkseid represents a cosmic-level Superman villain who pushes the Man of Stell to his absolute limits. Their battles are often epic in scale, with the fate of entire worlds hanging in the balance. Darkseid's unwavering belief in his own divinity and right to rule makes him a chilling antagonist. He embodies the antithesis of everything Superman stands for–hope, freedom, and the inherent value of life.

Bizarro serves as a funhouse mirror reflection of Superman, embodying the hero's powers but lacking his moral compass and intellect.

Metallo represents a unique fusion of technology and Superman's greatest weakness.

Mxyzptlk challenges Superman in ways no other villain can, using his reality-altering abilities to create bizarre and often humorous scenarios.
