"I am destiny incarnate, inexorable and inescapable. You are nothing. Insects fated to be crushed beneath my heel without a moment's thought. Fighting is useless. Surrender."
—The Anti-Monitor to the Paragons[src]

Mobius,[1] also known as the Anti-Monitor, is a being of supreme power and malevolence that embarked on a mission to eradicate the original multiverse by whatever means necessary. Despite being opposed by his counterpart, Mar Novu, he was ultimately successful thanks to the use of his invention, the antimatter cannon.

However, through the combined efforts of the Paragons and Oliver Queen, the multiverse was rebooted (or a new multiverse was created in place of the destroyed one which is also possible). In a last-ditch attempt by the Anti-Monitor to destroy the newly formed Earth-Prime's heroes, he engaged them in combat by expanding himself to giant stature. He was finally defeated by a shrinking weapon courtesy of Ray Palmer, Nash Wells, and Ryan Choi, which locked him in a perpetually shrinking state that sent him to the microverse, in which he can do no harm or interact with the new multiverse in any way for the foreseeable future indefinitely.

Biography

Creation

When Mar Novu traveled to the temporal zone, he was overwhelmed by chronal radiation as his presence caused an influx of antimatter, transporting him to the netherverse and somehow creating Mobius, an antimatter doppelgänger of his, as well as giving him a means of escape from there.[2]

Imprisoned

Seeking to destroy the multiverse with waves of antimatter, the Anti-Monitor was sealed behind a door in a Eternium-encased chamber where he built an antimatter cannon to help execute his scheme.[3] When Barry Allen of Earth-90 charged towards Novu and was repelled into the Nexus, he found himself within the reach of the Anti-Monitor, who whisked him into his prison and forced him to run on a treadmill to power the weapon in the Nexus.[1] During a test run of the antimatter cannon, the entire universe of Earth-2 was eradicated by Mobius.[4]

Messaging Nash Wells

Nash submits to the Anti-Monitor.

On December 9, Harrison Nash Wells, mistaking the Anti-Monitor for Mar Novu, stood outside his door and taunted him, saying how he didn't believe in false gods. He argued with Nash to no end, when suddenly Nash was attacked by one of Ramsey Rosso's blood brothers. After a while, Ramsey and his army were stopped thanks to Allegra Garcia, but Nash believed it was "the Monitor" who saved him.[5] At 11:58 pm, just as Nash was about to open the portal to what he believed would be the Monitor's realm, he noted on how he wished to know the truth and offered to reveal to him what he wanted to know in exchange for his service. He told him to stop his attempts to kill him and begin a new life. When Nash asked the Anti-Monitor to show himself, he said that he already has "the knowledge" (probably to solve a code). After Nash solved the code in the cave, the Anti-Monitor opened the rock and pulled him inside it in a flash of light before slamming down the rock wall again.[5][6][7][8]

The Central City Citizen 2024 article.

At midnight, on April 25, 2024, the sky turned crimson. The Anti-Monitor is not mentioned in the newspaper article written by Iris West-Allen after the Flash disappeared; however, there is enough evidence to believe he was involved in this version of the Crisis:

Current timeline

Released

Due to Nash opening the door, the Anti-Monitor was released and the Anti-Monitor Crisis began. He began destroying numerous universes across the original multiverse. Having activated the cannon, antimatter swept through countless earths and destroyed almost all of them.[10][1]

Recruiting Outkast

At some point, he recruited and presumably gave powers to an individual, who would later be known as Outkast, to help destroy the Earths. Outkast eventually killed himself, but not before he destroyed Earth-D and Earth-76, and killed Kid Flash.[11]

Hands on Destruction

Knowing of threat posed to him by the Paragons, Mobius went to Earth-12 to destroy it to keep Felicity Smoak from reading the Book of Oa for clues. However, she succeeded and gave vague clues to Mar Novu. Mobius then retreated to allow his antimatter cannon to keep wiping out life and universes.

Corrupting Harbinger

Mobius meets Harbinger.

Due to more worlds being destroyed, the Anti-Monitor soon communicated with Harbinger through their shared connection to Novu and, despite her pleas to stop, forcibly summoned her to his lair. Once she arrived, he introduced himself. After revealing that worlds were falling under his power and every death allowed him to steal more power from his positive counterpart, he demanded Harbinger's cooperation and proclaimed that there was work to be done.[12]

Mobius' successful endgame

Harbinger possessed by the Anti-Monitor.

The Anti-Monitor possessed Harbinger and after all except Earth-1 was destroyed and all the multiverse's refugees were brought to that last remaining universe, he teleported to the Waverider and tried to fool the multiverse's heroes. However, they deduced the truth and came at Lyla. He overpowered the heroes and, with his immense power, he murdered Mar Novu, as well as singlehandedly generate one last Antimatter wave to destroy Earth-1 and the timeship along with the multiverse's survivors as the heroes helplessly watched.[1]

As the wave was heading towards the ship, Pariah teleported the multiverse's last line of defense to a place where the Anti-Monitor could never find them, which angered him. Before they died, the remaining heroes with their last breath warned him that those that Pariah saved would "fight to their last breath". He scoffed at this and retreated by releasing his control from Harbinger before the Antimatter wave destroyed them and the timeship, completing his victory, despite the fact that he failed to kill the Paragons.[1]

The battle at the dawn of time

Once Jim Corrigan taught him how to use the Spectre's power, Oliver headed to the Vanishing Point to rescue the Paragons. Despite the danger Spectre's energy posed to the Speed Force, Oliver hesitantly gave some to Barry to unlock his full potential. With his increased speed, Barry ran through the Speed Force, but was ambushed there by the Anti-Monitor (who sensed their movement back into the remnants of the multiverse), losing everyone else across the Speed Force.[2]

Once Barry retrieved everyone, they arrived at the antimatter universe at the dawn of time, only to learn that the Anti-Monitor was waiting for them. He told the Paragons that some fates are inescapable: they may have stopped one version of Mar Novu from going through the experiment, but with another version of Mar Novu, he would always be created. He then unleashed an army of shadow demons.[2]

With Oliver's encouragement, the Paragons ran headlong into battle, fighting the shadow demons while Oliver and the Anti-Monitor watched from above. The Anti-Monitor told Oliver that it’s too late to stop him and that after 10,000 years, he will finally be victorious. Oliver replied that he won’t win and that he believed his entire life has prepared him for this fight. The Anti-Monitor proclaimed that all life ends, and only he is eternal, so Oliver took off his hood and told the Anti-Monitor that "we'll see about that."[2]

Spectre and Mobius's final fight.

Oliver and the Anti-Monitor engaged in a fight for reality, with The Spectre's powers countering the Anti-Monitor's antimatter blasts. The two grappled up close, with Oliver holding the Anti-Monitor's cold gaze. Telling the Anti-Monitor that he had failed this universe, the Spectre unleashed a surge of power to create a new universe, with the Paragons providing additional assistance via Lex's Book of Destiny page while seemingly vanquishing the Anti-Monitor. As a result, however, Oliver died a second and final time in Barry and Sara's arms.[2]

Endgame

However, the Anti-Monitor was reborn with the new multiverse and manifested on Earth-Prime, sending his Shadow demons to attack the Paragons as his first strike in his retaliation for his first defeat. Ryan and Ray realize that he cannot be killed because he's made of antimatter (reasoning it works on the same principle as energy cannot be destroyed; only redistributed), but they can destabilize his form, and have him shrinking for eternity. The heroes leap into fighting the shadow demons and as they do, the Anti-Monitor reveals himself to the Paragons and announces his new plan to renew his destruction of the new universe and tells the heroes that they are nothing but insects fated to be crushed by his heel.[13]

He goes to tell them that fighting is useless and forces them to surrender. The heroes dedicate their fight to Oliver and his sacrifice to restore the universe. They then go on to fight the Anti-Monitor, but he easily deflects all of their attacks. After an intense stare-off with Sara reminds him of Oliver defeating him, the Anti-Monitor then makes himself grow to an unprecedented height while yelling out that the Age of Heroes ends now.[13]

Martian Manhunter, Supergirl, and Superman all launch attacks from the sky at the giant version of the Anti-Monitor in order to try to buy Ryan, Ray and Nash some time with building the bomb that will take care of the Anti-Monitor. Once it's finished, Barry takes Ray with him to help out in the final fight with the Anti-Monitor. Ray gives the bomb to Supergirl while telling her to throw it like a girl. Kara uses it on the Anti-Monitor and sends him to the microverse. The Anti-Monitor shrinks away, defeated and thus bringing his threat to an end once and for all.[13]

Nash Wells made sure the Nexus was sealed (as with any remains of the antimatter cannon) to keep any slim chance of contacting and bringing Mobius back at zero percent.[14]

Lex Luthor as Anti-Monitor.

Months later, Mobius was criticized by Lex Luthor for his failure; Lex decided to remake the universe one planet at a time.[15] Dreamer saw Lex in the Anti-Monitor's armor in her vision.

Personality

Mobius is an incredibly evil being, as seen by him wanting to destroy the entire multiverse and kill off an infinite amount of innocent lives without any guilt or remorse.[12] He seems to enjoy taking credit for destroying universes and consuming worlds. He is also extremely intelligent and manipulative, as he was able to convince the extremely intelligent Harrison Nash Wells into freeing him.[5][6][7][8] Ultimately, his intellect prevailed as he succeeded in his mission.[1]

Mobius can be described as a megalomaniac (which Supergirl is quick to state) with a god-complex since he wants to replace the multiverse with his own realm in order to be the absolute ruler. In simpler terms Mobius hates what he cannot control; he wished to wipe out the multiverse so no one would oppose him. Or it's possible that he's just a basic creature that simply desires destruction of positive matter since it's naturally contrasting to antimatter.

After realizing that Paragons were the real threat to his plans due to their ability to restore the universe with the Spectre, Mobius learned from his mistakes and sought to kill them. Though he has little patience for subterfuge, deciding to manifest through his shadow demons after they failed to assassinate the Paragons.
