Earth-3 Superman from Earth-0's evil counterpart and a Kryptonian once again. The Superman of Post-Crisis Earth-4 is Captain Allen Adam, the Quantum Superman, and one of the most powerful beings in all of the 52 Earths. An amalgamation of Captain Atom (a Charlton Comics superhero based on Superman and later acquired by DC) and Dr. Manhattan of the Watchmen maxiseries (a pastiche of Captain Atom), Air Force Captain Allen Adam gained his quantum abilities when he was disintegrated in a blast caused by an experimental U-235 engine. The U-235 particles fused with his body, and his disembodied consciousness built an enhanced copy of his former body, but he keeps his "quantum senses" at a managed level by using drugs.

When visited during Countdown, a German Superman called "Herr Superman", who serves in Monarch's army, is seen, but it is not certain what world he is from. In The New 52, Earth-8 is home to a Superman analogue named Hyperious who is a pastiche of Marvel's own Superman pastiche Hyperion. He is a member of an Avengers pastiche team named the Retaliators. Hyperious' current whereabouts are unknown. The Superman from DC's Tangent Comics imprint is a radically different character from the traditional Superman. Due to an experiment conducted on an entire town by a government black ops group called Nightwing, Harvey Dent was the lone infant survivor of a failed super-human program that killed hundreds. After growing to adulthood, and falling from the world's tallest building in an attempt to save a suicidal man, his dormant powers activate and he
