In ‘Final Crisis: Superman Beyond’ (2008) #1, Superman and Captain Marvel/Shazam lift the Book of Limbo. Really, it is a book with an infinite number of pages. In “Superman, The Greatest Story,” I argue that it is feats that define Superman’s story. In ‘Final Crisis,’ Superman is not only the strongest story, he is also the strongest hero. Definitely, this feat takes the top spot on this list.

In the conclusion of the “Sixth Dimension” storyline, Superman battles against the World Forger. Freed from his prison on Prime Earth, Superman sundips multiple times in yellow suns. Then, flying at high speeds through the cosmos, Superman reaches the speed of light. In an instant, he becomes a line and all time and space is perceptible to him. With a devastating punch, Superman shatters the World Forger’s 20 billion years old multiverse.

VISIT FEAT: SUPERMAN, ‘JUSTICE LEAGUE’ #25

Superman and Wonder Woman are two of the strongest warriors in the DC Universe. In ‘JLA/Spectre: Soul War’ (2003) #1, the Spectre comes to ask the JLA for help to stop the Trans’ invasion. During the invasion, Spectre merges with the JLA. As the Spectre and JLA investigate, Spectre is knocked unconscious. In free fall, Superman and Wonder Woman lift Spectre.

Indeed, considering the free fall and that Spectre’s weight is eternity. Definitely, this feat requires infinite strength.

To sum, “Infinite Crisis” is largely a question about who is the true Superman. Indeed, Earth-One Superman, Earth-Two Superman, Superboy and Superboy-Prime all contended for the title.

During the crisis, Earth-Two Superman successfully brought back Earth-Two with Alexander Luthor Jr’s help. And, when Earth-Two Lois Lane died, Earth-One Superman journeyed to Earth-Two to help. However, Earth-Two Superman blamed Kal-El for her death.

Dangerously, a clash followed between the two Supermen that threatened time and space. The Men of Steel’s punches threatened reality and opened a rift of chronal energy. Then, each Superman was transported to the other one’s Earth, reliving its history.

Eventually, Wonder Woman had to come to Earth-Two to restrain Earth-Two Superman. To consider, opening a chronal rift requires time travel. Definitely, this feat requires infinite strength.

Well put, Superman asks Brainiac-13 “What’s infinity times infinity?” In ‘Action Comics’ (2001) #782, a cosmic Superman transports B-13’s Warworld an instant after the Big Bang.

During “Our Worlds At War,” Imperiex sought to hollow the universe. When Imperiex’s armor was cracked, Brainiac-13 absorbed its energies into Warworld. To that end, Brainiac sought to rule the universe.

Via a temporal Boom Tube, the sundipped Superman transported Warworld to the beginning of time. Though, the temporal Boom Tube was created by Steel’s Entropy Aegis. Nonetheless, Superman’s feat still involved time travel.

Indeed, it is debatable whether the feat required an infinite amount of super strength. At the same time, pushing Warworld through a temporal Boom Tube definitely required an incalculable amount of super-strength.
