The world of Flashpoint debuted in the Flashpoint event (2011). It was an alternate timeline where the world became a living hell in the brink of destruction and only the Flash, (Barry Allen), was conscious about that.
Originally believed to be born of the manipulations of Professor Zoom, aka Reverse Flash, the Flashpoint universe was revealed to be created by the fracture in the fabric of reality caused when Barry Allen saved the life of his mother. An event than Barry didn't remembered.
This action caused waves than afected time and events in the past and future with cathastrophic consecuenses. The nature of the changes doesn't follow a pattern as in a domino effect. Instead, the changes were random not only affecting what happened after Nora Allen assassination attemp, but also affecting events before that point in time. As Zoom explained to Flash, he shattered history. His actions affected the speed force same way as a bullet throught a windshield, spreading forward and backward in time.
The metahuman presence was discovered earlier in this world but the hero activities were not such relevant. In the war field in fact, the Creature Commandos, leaded by Frankenstein were pivotal to win WW2. The absence of the Flash and the JSA (this was a distorted pre-new52 world) keep the concept of superhero unknown to the population. Most of the time, people with paranormal abilities would be subject of investigation and persecution from the different worlds armies.
The metahuman presence would explode with the war between Atlantis and Themyscira with cathastrophic consecuenses. Europe and the north of Africa were destroyed by Aquaman and his Atlanteans, meanwhile the British Islands became the new home of the invading forces of Wonder Woman and the Amazons. The war between this two factions proved to be too much dangerous for the rest of the world and in response the different global powers developted ways to destroy both enemies, without to know than the atlanteans possesed an ultimate weapon than could destroy earth itself.
In other places of the world the powers would shift towards people with superpowers: The Nazis lead by Captain Nazi sized the control of South America; Africa was under the control of Grodd's Gorilla Empire; Middle east was under Black Adam control; India was the rule of the Outsider; China was the defense zone of the Twelve Great and Japan had their own army of Red Tornados.
The climax of these tensions would explode in Flashpoint #5, when in the middle of a final battle among the superpowered forces, Barry Allen tried to restore the original timeline by stoping himself but the intervention of Pandora would give origin to the New52 reboot.
The only memento left from this universe is the letter written by Thomas Wayne to his son.
Main characters changes
Many of the established characters were changed as effect of the paradox:
- Barry Allen, even though he still remembered the previous timeline, never was Flash. Len Snart was the hero of Central City as Citizen Cold.
- Bruce Wayne was killed by Joe Chill instead of his parents. His father, pushed by guilt became Batman while his mother falls into madness and became the Joker.
- Cyborg was the USA's greatest hero.
- Abin Sur never crashed on Earth. He instead was Green Lantern meanwhile Hal Jordan still was only a test pilot.
- Kal-El ship's crashed in Metropolis, destroying twelve squares. Kal-El himself would spend his life in reclusion and under the care of Sam Lane as a part of Project Superman
- Wonder Woman and Aquaman were the leaders of their nations. They were lovers but after the assassinations of Hippolyta and Mera, they became bitter enemies.
- Nathaniel Adam never became Captain Atom. He instead reached General grade and became the chief of Project M and later Project Superman.
- Oliver Queen makes his fortune building super weapons and artifacts to stop metahumans.
- The power of Shazam was shared with the other members of the Shazam family, in a way more similar to the Infinity Man and the Forever People. Together, they summon Captain Thunder.
- Plastic Man still was a criminal.
Wildstorm & Vertigo characters incorporation
Even though the New 52 reboot incorporated the characters of Wildstorm and Vertigo editorial lines, an advance version of such could be saw in the different titles of the event:
Many new characters debuted as a product of the event and a few of them even made the step to become New 52 characters.
The characters of Flashpoint had reappered again in Convergence. The Gotham City from their universe is one of the bottled realities of Telos. Different characters were pitched against the pre-Flashpoint Gotham city characters. Several characters who died at the end of Flashpoint are alive in this city, so isn't clear from which moment exactly the city was stolen.
- Superman vs Flashpoint Abin Sur, Cyborg, Captain Thunder, Batman (Thomas Wayne) and Subject-1 (Flashpoint Superman)
- Flash III (Wally West) with Iris and Jai Allen against Flashpoint Wonder Woman and her amazons.
- Justice League of America (Jade, Jesse Quick, Mera, Vixen, Zattana and Supergirl) against Flashpoint Emperor Aquaman and his forces.
- Pre-Flashpoint Nightwing and Oracle (disabled Barbara Gordon) against Flashpoint Hawkman and Hawkwoman (who made their first appearance in Convergence miniseries)
- Question (Renee Montoya) and Two Faces are opposed to Flashpoint Harvey Dent.
Following the chaos and the rise of Deimos, Flashpoint Aquaman, Wonder Woman and the Furies joined the Wizard army to gain power over the world of Telos. However, the fall of the wizard of Skartaris and the change of heart of Brainiac, returned them to their cities, which were returned to their proper timelines/universes, including the Flashpoint Gotham.
DC Rebirth: The Button
The Flashpoint reality would be seen a last time in the Button story arc: when Batman began to investigate the mysterious button found hidden in the Batcave, he was attacked by Reverse Flash, who felt a great power hidden in the button. However, he suddendly vanished and returned with half his body destroyed, dyingto instantly.
To investigate what happened to him, Flash and Batman traveled used the cosmic treadmill to follow the vibrational trail of the button and both found themselves in the batcave of the Batman of the Flashpoint reality, Thomas Wayne. With the Cosmic Treadmil damaged, Flashworked on repair it meanwhile Bruce tried to reconnect with his father and learn his history.
Thomas had survived his last encounter with Zoom, during the final attack in New Themyscira but was on the run, hunted by atlanteans and amazons. However as he found with his son and under attack from his enemies, the flashpoint reality was collapsing around them. Flash and Batman, with the treadmil reparied, barely escaped, not without Thomas Wayne advising his son to quit the mantle of Batman.
After that, the Flashpoint reality was at last apparentely erased by the same force than force behind the last mysterious events plaguing the DC universe. Depiste their final destruction, it is possible than the Flashpoint universe persists among the waves of the hypertime, beyond the multiversal bubble.
The world of Flashpoint is featured in the AOM Justice League: The Flashpoint Paradox.
