History
Origin
Heir to the Kingdom
While traveling through the Multiverse, Barry Allen of Prime Earth reflects on his exploration of the Multiverse, noting that while most alternate Earths show minor variations, some diverge in significant ways. During this journey, he briefly glimpses Earth 22 and recognizes it as a world that presents a serious cause for concern. After returning to Prime Earth, Barry informs Superman and Batman that he has located Boy Thunder, who had vanished into the Multiverse months earlier,[1] though someone unfamiliar appears to be influencing him. Barry assists in calibrating a modified Cosmic Treadmill, before Superman and Batman depart alone for Earth 22 (Alternate Earth 22 Future), where they briefly struggle to synchronize with the world’s vibrational frequency.
On arrival, they observe an older Clark and Bruce surveying the graves of fallen heroes, including counterparts of Ted Kord, Kara Zor-L, and Raymond Terrill, alongside numerous other heroes, suggesting catastrophic losses. Batman questions what could have caused such devastation, pausing at Red Robin’s grave. A temporal shift brings them back to the physical world, placing them on top of Earth 22’s Daily Planet. Superman notes that this Earth resembles their own but is set several years into the future and suggests contacting Earth 22’s Kal-El for guidance regarding David. Seeking to gather information before approaching their counterparts, Clark and Bruce visit Planet Krypton, a civilian restaurant owned by Booster Gold. While observing the cultural differences of this future Earth, they discuss David’s situation and the troubling implications of the fallen heroes they witnessed. During this investigation, Clark confirms that Earth 22 has no recorded knowledge of the Multiverse, marking a significant divergence from their own Earth.
Meanwhile, David, now calling himself "Thunderman", is engaged in combat with a supervillainess known as Atom-Master, who had kidnapped several scientists. During the encounter, Thunderman demonstrates considerable power and aggression, prompting Superman to intervene to prevent him from causing lethal harm. The battle reveals that David has aged and developed a more tactical, combat-ready appearance, including a domino mask, jacket, and utility pouches. Although initially overjoyed to see Superman and Batman, this proved to be a ruse, as he then grabbed Superman by the throat and tried to electrocute him.[2]

Kingdom Come
In the early 21st century, after the Justice League of America disbanded, younger heroes looked to the example of a violent vigilante named Magog, who killed the Joker and was publicly pardoned. Disillusioned, Superman retreated to the Fortress of Solitude for ten years while many heroes either withdrew from society or became increasingly extreme in their methods, leading to widespread destruction and the near collapse of human society. Superheroes battled each other, destroyed cities, and obliterated prisons for metahuman criminals. Humanity became powerless and irrelevant amid the rise of god-like superhumans, while the original Justice League’s legacy continued only through descendants and symbolic ventures. A nuclear disaster in Kansas caused by a battle between Magog’s Justice Battalion and Parasite killed nearly a million people and devastated the region. Wonder Woman convinced Kal-El to return, and he reformed the Justice League, ending his self-imposed exile and becoming an active example for the world once again.

New 52
After the retirement of Superman led to the mass surrender of the superheroic old guard, a new generation of superbeings ran amok until the destruction of Kansas forced Kal-El's return.[3] The Sons and Daughters of the Bat, inspired by Batman, opposed him.
Its heroes would come to aid in protecting the Multiverse against The Gentry.[4]

Notes
- This reality is the setting of Alex Ross and Mark Waid's Kingdom Come continuity in the Post-Flashpoint Multiverse. It is based on the original Hypertime world of Earth-96, but it is more a direct continuation of Pre-Flashpoint Earth-22.
- Although Earth 22 is first named and shown in The Multiversity Guidebook #1, its first full appearance is in KFC: Crisis of Infinite Colonels #1. Considering that the canonicity of Crisis on Infinite Colonels remains dubious, the first official appearance of this reality is in Young Justice (Volume 3) #7.
- The existence of Starman/Thom Kallor implies that some version of the Final Crisis: Legion of 3 Worlds storyline may have occurred on Earth 22– some time between the events of Heir to the Kingdom and Kingdome Come.
- In the original Pre-Flashpoint continuity, Starman was originally brought to Earth-22 on his way to New Earth in order to prepare for the resurrection of Superboy.
- However, he could either be a Starman native to this Post-Flashpoint universe.
- Earth 0 Flash/Barry Allen claimed to have named Earth 22 himself.[2] However, this seems to be false, as the Earth designations of the Multiverse– at least those of the 52 local worlds– are based on the Monitors classification.
Trivia
- Earth 22 is opposite Earth 7 in the structure of the Multiverse.
