#once again: the only multiverse designation consistencies remain Earth-3 being the Crime Syndicate and Earth-11 being the genderbent Earth

[fantastic-nonsense]

the sheer comedy of knowing that literally everyone is going to ignore Earth-16 being called one of the Multiversity Earths and will continue to refer to it as "The Young Justice cartoon universe"

In the very beginning of existence, there was only The Source and from it, the positive Anti-Crisis Energy were born and pulled together by an Unseen Hand.[2] It was throughout the void of the Greater Omniverse that The Source sent The Hands, a group of super-celestial beings using the Anti-Crisis Energy to birth Multiverses. With the creation of their Multiverse, each member of the Hands would pass on and allow their energies to return to The Source.[2] However the rogue among them refused her fate and wanted a vicious reality meant to live forever in a self-renewing loop of crisis and rebirth.[3] The name of that rogue super-celestial was Perpetua.

20 Billion Years Ago

She created the first iteration of the Multiverse using the negative Crisis Energies and created her three sons Mar Novu, Alpheus and Mobius, as its first inhabitants.

Once created, Perpetua explained to them that her Multiverse comprises of three main realms made out of the three basic forms of matter- dark matter, positive matter and antimatter, and created them to monitor these realms. She assigned Alpheus to the dark matter realm beneath creation where he would build the myriad universes of creation. Mar Novu was assigned to the positive matter realm, where he would guard the many universes that rose out of the dark from cosmic crises. Mobius was assigned to the antimatter realm where he would prevent the light of creation to breach the Greater Omniverse.

Curious, Mar Novu asked Perpetua what her purpose in this Multiverse was, as her role as creator had already been fulfilled. She told him that she would remain to make sure that all of her children lived.[4]

15 Billion Years Ago

Perpetua called upon Mar Novu to show him her greatest creation. Perpetua had searched the endless worlds of the Multiverse looking for the perfect creation, but could not find it. Disappointed in what saw, Perpetua bound the Martians with the Humans, creating the Apex Predators; perfect killing machines that would live and fight until the end of time. Upon seeing what his mother had created, Mar Novu told her that he found a cosmic judgement coming for them because of her actions and that she was well aware of that and wished to fight back. Perpetua then tried to share her point of view in vain, leading her to order her Apexes to attack Novu, forcing him to flee.[4]

Two hundred thousand years later, Mar Novu told his brothers what he had seen and they agreed that her kinds, the Hands needed to be alerted of her doings. They were interrupted by Perpetua who witnessed their betrayals and sent her Apex Predators to attack her sons.



The fall of Perpetua and her Great Army

The Hands's response was to send the Cosmic Raptor to stop Perpetua's plan. Unable to defeat the Cosmic Raptor, Perpetua, her Apex Predators and the totality of her power were taken to the Source Wall and imprisoned in it. The Hands recreated Perpetua's Multiverse, allowing the Multiverse to evolve without intrusion. Perpetua was trapped and forced to watch it all.

After the recreation of the Multiverse, the story of Perpetua was hidden by Krona and the other Maltusians who gathered all evidence.[5] She witnessed the tampering of Krona, preventing her Multiverse to set in a stable form.

She was forced to watch her Multiverse grow more and more unstable. She knew its final fate: it would die, and she would die with it. As the only thing that would break her prison was an action that would crack the very foundation of reality, Perpetua began to whisper in the mind of her son, the Anti-Monitor, instigating him to cause the first Crisis. After the Anti-Monitor's defeat, a crack formed on the wall, allowing Perpetua to whisper out, through the Multiverse, into the ears of those powerful enough to cause Crises over the years.[2]

Source Wall Breaking

After the invasion of the Dark Multiverse by her last scion, Barbatos and the Batman Who Laughs, the Source Wall was finally broken and Perpetua was freed from her prison, the Totality which landed on Earth-0 after the wall breaking.[6] Her corporeal form was restored by Lex Luthor with almost six parts of her dark powers unlocked.[1]

Year of the Villain

At some point, she awoke and remade Lex Luthor into an Apex Predator as her second in command after the latter faked his own death.

Doom Rising

While the Justice League divided into two them, one for the Totality's shards which were across time and the other for recruiting Mobius, Perpetua and Lex were heading to the Promethean Galaxy with the intent to recruit her son Mobius. Meanwhile, Hypertime was within the grasp of Perpetua, allowing the Legion of Doom, who were in different timelines, to affect them as they see fit without erasing their present.[7]

Arrived in the Promethean Galaxy, she was confronted by Mobius and his brothers alongside the Justice League. During the fight, the three brothers merged together to form the Ultra-Monitor, strong enough to fight their mother.[8] At the end of the battle, Starman and his analog from the past and future were going to open a portal to bring the rest of the Justice League who gathered the shards of the Totality across the past and the future. However, due to the fact that the psychic energy shifted toward doom and Hawkgirl's vendetta against Lex Luthor who previously absorbed J'onn J'onzz within himself, the portal closed before the rest of the league could join the battle and Perpetua was restored to all her might.

She then granted the Anti-Life Equation to Mobius who betrayed his brothers.[9] Perpetua then crush Starman on her fist and and exclaimed that she have the entire Multiverse to remade.[9]

Perpetua came to Earth 19, noticing that this world has doom in its core but its people still chose justice thus, she destroyed this universe. She then returned to the Promethean Galaxy explaining her plan to Lex and Mobius and remade every human who believes in doom into Apex Predators.

At some point, the Legion of Doom returned to claim their rewards from Perpetua. Her response was to turn Brainiac into her throne and the other members as conduits of power for Lex now wielding the The Seven Forces of the Universe.[10] Later, she came to Earth 44, asking its people on whether they choose to join or oppose her. Among all people of this Earth, Dr Will Tornado was the only one answering, telling her that whatever god she is, his machines have more divinity in their metal hearts than her.

Perpetua replied that these words have no place in her new design and started considering to destroy Earth 44 but was interrupted by a call from a helpless Mobius. Perpetua then tell Dr Will Tornado that she know a parfect place for his Earth and throw it toward her sons who were recently freed from their brother thanks to John Stewart's intervention but they managed to flee before the impact thanks to Alpheus' sacrifice.

Much later, Perpetua came to Earth-0 to confront the Justice League who had defeated Lex Luthor and gathered Hawkgirl, John Stewart and J'onn J'onzz. During the confrontation, J'onn managed to reach out the minds of all the people of the planet, trying to convince them to break free of Perpetua's lies which shifted the psychic balance toward justice, strings of energy started to wrap up Perpetua.

However, just as the victory was near for the league, the balance shifted for doom again, breaking free of her bonds, Perpetua explained that she allowed the psychic connection J'onn had with Earth's people to happen because she wanted them to see their people rejecting them since she was the creator of the Multiverse and also explained that she left a piece of the Totality across time for Vandal Savage who will recruit the Luthors to found a way to unlock her powers as she planned. She then obliterated the Justice League however without her knowing, the league were saved by the Quintessence.[11]

Hell Arisen

After the fall of the Justice League at Perpetua's hands, the Multiverse was at her and Lex Luthor mercy. When the Crime Syndicate of Earth-3 came to Perpetua, requesting more power, Perpetua's response was to turn their people into Apex Predator and killing Johnny Quick after his disagreement to join her.

After the meeting Perpetua had with the Crime Syndicate, she send Lex Luthor to Earth-0 in order to eradicate the dark energy incursion caused by the The Batman Who Laughs. Much later Lex came to Perpetua with the defeated Batman Who Laughs. However, The Batman Who Laughs used his superior knowledge to convince Perpetua to choose him over Lex as her second in charge. Perpetua then depowered Lex for his insolence and send him back to Earth but not before Lex learns that the glorious vision of the future he has had was an hoax made by Perpetua in order to manipulate him.[12]

Dark Nights: Death Metal

Perpetua was confronted by the Justice League at an unspecified date. She wielded all the Crisis Energy as the league were harnessing Doctor Manhattan's energy, consisting of all the Anti-Crisis Energy.[3] As their battle raged, Perpetua taunted Diana, telling her that if she won using the positive energies, every history including those forgotten due to Crisis would matter, many people would be dead. Scared by this truth, Diana hesitated long enough for Perpetua to regoup call on The Batman Who Laughs.[13] The fight ended on a massive blow that burned the sun and has exhausted both energies.[3]

The Batman Who Laughs helped her to regain strength using the Dark Multiverse, whose three worlds of unending Crises made it a hub of the negative energies that would keep powering Perpetua through multiple antennas around the Multiverse. Having gained enough power to destroy the rest of the Multiverse, Perpetua took over reality and proceeded to reshape it as how she wanted, while rewarding Laughs with Earth-0, reshaping the world for him.

She destroyed Earth-22 as well as most of the universes that doesn't match her dark ideology, reducing the Multiverse from fifty two universe to only eight. Later, Perpetua came to The Batman Who Laughs, telling him that only six universe remains. Untrusting him, she also warns him about if he usurp her, her kind, the Hands would come, seeing what's been done in the Multiverse and they will destroy it all.[14]

Perpetua would later destroy the House of Heroes and would sent her Dark Multiverse's minions on the Justice Incarnate and the Green Lantern Corps who were trying to destroy all the antennas in order to cut her off from her source of power.[2] Thanks to Owlman who had trapped each tower with a detonator, they managed to destroy every tower and leave the areas despite this, Perpetua was still powerful enough to destroy the remaining universes though her unlimited source of power was cut.[2]

After the rise of the The Batman Who Laughs, now known as the Darkest Knight, who tricked the Trinity in order to redirect all remaining Crisis Energy from three worlds of never ending Crisis to him instead of Wally West, Perpetua battled the Darkest Knight head-on, with all of the remnants of reality collapsing in the chaos around their duel.[15]

Despite being cut off from their primary power sources thanks to the machinations of the remaining heroes, both powerful beings continued to war against each other.[14] Growing exhausted and weaker as the remaining Crisis Energy was redirected to the Darkest Knight, Perpetua offers a partnership with the him, arguing that it's only her that keeps her kind from coming to the Multiverse and wiping it out. But the Darkest Knight is hoping for just such an outcome in order destroy them himself. With Perpetua all but spent, the Darkest Knight reveals his last trick, using his powers, the Darkest Knight pulls together the remaining parts of the Source Wall that had once contained her. Despite her pleas, the Darkest Knight seals her within the remnants of the wall and destroys them, ultimately ending Perpetua's life.[16]

As the final battle between the Forge of Worlds-empowered Wonder Woman and the Darkest Knight raged, they fall back through time, to the beginning of the universe itself. They saw the Hand of Creation sparking the Big Bang which the One who Laughs has recognized as Perpetua'
