Mobius

"Universe after universe has fallen before my power. World after world consumed. With every death, I steal my mirror’s strength and mine grows ever stronger. Who am I? I am the Anti-Monitor. Come, Harbinger. There is work to be done."

- Anti-Monitor

Mobius, also known as the Anti-Monitor is a being of supreme power and malevolence that aims to eradicate the multiverse by whatever means necessary. He is opposed by his counterpart, the Monitor.

Biography
The Anti-Monitor was inadvertently freed from confinement by Pariah. Following this, he sought to destroy the multiverse with waves of antimatter.

Messaging Nash Wells
On December 9, Nash mistook Mobius for Mar Novu, and stood outside Mobius's door and taunted him, saying how he didn't believe in false gods. Mobius 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. At 11:58 pm, just as Nash was about to open the portal to what he believed would be the Monitor's realm, Mobius noted on how he wished to know the truth and offered to reveal to him what he wanted to know in exchange for his help stopping the Crisis. Mobius told him to stop his attempts to kill him and begin a new life. When Nash asked Mobius to show him, he said that he already has "the knowledge" (probably to solve a code). After Nash solved the code in the cave, Mobius opened the rock and pulled him inside it in a flash of light before slamming down the rock wall again.

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, Mobius 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, Mobius demanded Harbinger's cooperation and proclaimed that there was work to be done.

Personality
The Anti-Monitor seems to be an incredibly evil being, wanting to destroy the entire Multiverse, killing off trillions, if not infinite innocent lives without any guilt or remorse. 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.
