"It is time to end the age of heroes and everything you hold close."

Mobius,[1] better known as the Anti-Monitor, is a being of supreme power and malevolence that embarked on a mission to eradicate the multiverse by whatever means necessary, opposed by his counterpart, Mar Novu, in which he was ultimately successful.



At some point, Mar Novu allowed for Mobius to live, a decision the former would come to immensely regret.


Seeking to destroy the multiverse with waves of antimatter, the Anti-Monitor was sealed behind a door in a chamber where he built an anti-matter cannon to execute his scheme. When Barry Allen of Earth-90 charged towards Novu and was repelled, 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. During a test run of the antimatter cannon, the entire universe of Earth-2 was eradicated.

Messaging Nash Wells

Nash submits to Novu

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.[2] 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.[2][3][4][5]

The Crisis of 2019


Due to Nash opening the door, the Anti-Monitor was released and the Crisis of 2019 began. He began destroying numerous universes across the multiverse.

Recruiting Outkast

At some point he recruited an individual called Outkast to help destroy the Earths. Outkast eventually killed himself, but not before he destroyed Earth-D, Earth-76 and killed Kid Flash.

Corrupting Harbinger

Due to more worlds being destroyed, the Anti-Monitor soon communicated with Harbinger through unknown means 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 for him to steal more power from his mirror counterpart, he demanded Harbinger's cooperation and proclaimed that there was work to be done.[6]

His successful endgame

The Anti-Monitor possessed Harbinger and after all except Earth-1 was destroyed and all the multiverse's refugees were brought to last remaining universe, he teleported to the Waverider and tried to fool the multiverse's heroes. However, they saw through his guise and futility tried to kill him. He overpowered the heroes and had his Antimatter wave destroy Earth-1 and the multiverse's survivors as well as murder Mar Novu as the heroes helplessly watch. 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 angers him. Before they died, the heroes with their last breath warned him that this isn't over and those that Pariah saved will "fight to their last breath" just before the Antimatter wave destroyed them, completing his victory, despite that he failed to kill the Paragons, who are the only ones that can defeat him.


Mobius had proven to be an incredibly evil being, wanting to destroy the entire multiverse, killing off an infinite amount of innocent lives without any guilt or remorse,[6] he seems to enjoy taking credit for destroying universes and consuming worlds, he is also extremely intelligent and manipulative, able to convince the extremely intelligent Harrison Nash Wells into freeing him.[2][3][4][5] Ultimately, his intellect prevailed as he succeeded in his mission.[1]

Mobius can also be described as a megalomaniac with a god-complex since he wants to replace the multiverse with his own realm to be absolute ruler.

Behind the scenes

  • In the comics, the Anti-Monitor is a major antagonist and the main villain in Crisis on Infinite Earths. As The Monitor's evil antimatter counterpart, he sought to destroy the multiverse and replace it with his Antimatter Universe. Decades later in the New 52 storyline Forever Evil, he returned with a new design which the show's version is similar to, and later still in the Rebirth comics, his real name was revealed to be Mobius.
  • The Anti-Monitor is the most dangerous villain in the shared multiverse as he is with the largest body count. Except for the Paragons, he has murdered an infinite amount of people by destroying the multiverse with antimatter.
  • His physical appearance has been compared to other major pop culture villains, such as the Marvel villains Apocalypse and Thanos as well as the White Walkers and their leader in particular, the Night King, from Game of Thrones .
