Monty (Zombies)

"This... is... it. The Aether, the infinite, the reality beyond. Beyond the world you know, beyond your perception. Things are going to get a lot worse before they get better. You changed the rules. There are certain things that you can't ever change. All I ask, is that you do the right thing. The right thing for everyone."

- Dr. Monty

Doctor Monty is a character that appears in the Zombies mode of Call of Duty: Black Ops III. He is the creator of most of the features in the mode itself like: the GobbleGum Machine and the Factory that creates them, the appearances of the Mystery Box, chalk drawings, Power-Ups, Persistent Upgrades that appear in all the Zombie maps. He is also a member of the ancient Keeper race, though throughout all his appearance he has only assumed a human form of an old British man wearing a signature red scarf.

Overview
Monty, like his Keeper brethren, existed since the very beginning of the universe. Not much is known about his history, other than that he used to have one person he considers his best friend. That person would later be corrupted by the energy of the Dark Aether, and be known as the Shadowman. After a war breaks out, Shadowman and the rest of the corrupted Keepers were banished to the Dark Aether, where they would eventually mutate into Apothicons. Monty and the Keepers took up the mantle of guardians of the universe, watching from afar and only interfering when the universe is in a state of imbalance.

On October 28, 1945, upon the teleportation of four individuals: Edward Richtofen, "Tank" Dempsey, Takeo Masaki and Nikolai Belinski (otherwise known as Ultimis), the universe began to show instability. Due to Monty being unable to directly interfere (violating human's free will), he offered indirect support through "little nudges", such as assisting Group 935 in producing special elixirs that would be later known as Perk-a-Colas, and adding chalk outlines of weapons all around. It wasn't until the arrival of a drone carrying a human brain at Agartha that forced Monty to take a different measure. Using his power, Monty created a physical body for Ludvig Maxis resembling that of his own in Dimension 63, and allowed him to reside at the House in Agartha. He then retrieves Samantha Maxis from the original timeline, wiping out the Maxis of this dimension from existence as well; however, realizing that Samantha had been corrupted by the Dark Aether as well, he was forced to separate the father-daughter pair, and returned her to him later after cleansing her soul and restoring her innocence.

Monty then informs Maxis that the only way to save everyone at this point would be to separate Agartha from the rest of the multiverse, sealing it from Apothicon influence. He instructs Maxis to find the Kronorium, a book which contains the location of an artifact called the Summoning Key, which can collect and store souls that survive the fracturing of the universe. After having Primis Richtofen retrieve it from Morg City in Dimension 63, Monty then accepts an innocent Richtofen soul, named Eddie, from Dimension 2210 into the House. He introduces Eddie to Samantha, and provided them toys to play with, comprising of various Zombies characters. He would keep a close watch on Richtofen later on, due to a sense of mistrust, and the nature of himself and his companions.

After Richtofen sends the souls to the House, Monty introduces himself by only speaking to Dempsey, Nikolai and Takeo, believing that Richtofen is doing "his own thing". He explains to them that he's suspicious of Richtofen's plans and tells them that everything will make sense once they reach "the House". He also attempts to explain his role in shaping up the universe, and his "nudges". Primis would then return to the House, where they destroy the teleporter and seal Agartha off from the rest of the multiverse.

However, Maxis would eventually be manipulated into accidentally releasing the Shadowman from the Key. While Monty tries to hold the dimension together due to the Apothicon's invasion, Primis would then try to find a way to defeat the Shadowman. Monty tries to reach out to Primis, telling them of the story behind the Keeper and Apothicon conflict, as well as the difficulty of his role. Eventually, with the help of Sophia, Primis defeats the Shadowman, and the Apothicons are banished once more, with the Summoning Key (containing Maxis and the children) lost in deep space. As Monty begins to ponder the future of his perfect world, he finds that Primis somehow remains alive, rather than disappearing from existence. He discovers that the four of them have consumed blood of souls that came from closed dimensions, thus causing a paradox. He contemplates wiping them out of existence as well, but then realizes that their cycle would be reset, and they would be sent back to medieval times to assist the Keepers in the Great War, effectively solving the paradox and completing the cycle of the universe.

At some point, Monty begins to watch over Ultimis and Primis once more, this time laying out recordings of himself talking about the events that transpired at the locations that both crew once visited in the previous cycle.

At the end of Primis' escape from Alacatraz, Richtofen post-Revelations returns, and warns Primis that they'll need Nikolai's soul to defeat Doctor Monty.
