Edward Richtofen (Ultimis)

The Omnicidal Doctor
There are two major timelines in COD Zombies from which all subsequent "fractures" (timelines) and dimensions deviate from: Primis and Ultimis. There is a constant: Edward Richtofen is a member of Group 935, a research group dedicated to analysis and distribution of Element 115, which are space rocks sent by ayy lmaos called Apothicons to destroy universes.

Ultimis Richtofen is... a troubled man. He's got voices in his head, after he accidentally went to the Moon and touched an ayy pyramid. This turned him insane and hell bent on finding Agartha, the origin of all the dimensions, by any means possible. But do that, he needed a plan. And a plan he had, indeed. He established the base on the Moon, conducted experiments on his boss' daughter, Samantha Maxis, and many other test subjects. The mad doctor pulled a sneaky on Doctor Maxis and launched him, Samantha and her little dog too to the Moon. After that the plan got derailed, seeing as the loli too grew mad with power after sealing herself in the Aether Pyramid, the one that gave Richtofen the crazies. Oh, and Dr. Maxis got uploaded onto the Moon's servers.

Still, that was a mere setback. Richtofen awakened three of his surviving test subjects, them being Nikolai Belinski, Takeo Masaki and "Tank" Dempsey. The uneasy alliance eventually got the name "Ultimis". With them, Richtofen could finally complete his Grand Scheme. Anyway, the team went through time and space itself, as the Doctor led his motley crew to a theater/nazi facility in the 60's, Russian Cosmodrome, Siberian Outpost in 2011, the mythical place of Shangri-La, where Richtofen was once revered, and finally, the Moon.

Such an erratic movement might have been seen as accidental, but it had a purpose. The Siberian Facility held the Vril Device, while Shangri-La was affected by a timeloop, caused by the Focusing Stone. Combined, these two artifacts were the centerpiece of Richtofen's plan.

The Ultimis went forward in time to 2025, right into Area 51, from where they teleported to the moon. There, Richtofen revealed his plan and betrayed his allies, transferring bodies with the zombie-controlling loli Samantha. Agartha was almost within his grasp. Yet, the Ultimis launched rockets upon earth, ravaging it and weakening Richtofen's connection to Aether.

Still, the mad doctor wasn't a schemist for nothing. The voices of Apothicons in his head told him what to do. In the ten long years of battle against Dr. Maxis, he fought tooth and nail for control over the Polarity Devices, to take the Earth back under his control. The two commandeered a group of survivors called "Victis", each vying to set them on their own side. That's where timeline splits.

In one, Richtofen succeeds, purges Maxis and Samantha from existence, and resumes his reign over the Earth. Well, that and he also became a passenger in Samuel Stuhlinger's, one of the Victis and the only who could hear him properly due to him eating a chunk of zombie a few times, body. What came after, is unknown.

In the other, Maxis proves victorious, and uses up the entirety of Earth to launch himself and Samantha into Agartha, while forever damning Richtofen to walk in a zombie's body. Also, the body of Richtofen that Samantha was occupying was turned comatose. Oh, and Maxis turned out to be a corrupt fucker on a dial with the ayys, but that's another story.

The zombified Richtofen ends up allying himself with Victis and a version of Primis Richtofen, in order to fix the fractures appearing across the dimensions, secure the blood vials and protect Victis from the annhilation of their home dimension. Completing that, Primis directs Zombie Ultimis back in time, to the Ultimis Crew that have been teleported to 1963's Area 51. The one with the braindead Richtofen. The Zombie touches the body and turns into ash, returning the soul back into Mad Doctor's body. And from there they are rescued by Primis, to take part in the Great War.

Convoluted as shit, yep.

The Ultimis had shown himself both in present and the past, under different circumstances in the TFR. After the events of the first half of Season 3, Ultimis came along with the rest of the wrestlers, while Primis went far far away, to set right a universe. Who knows where will the road of the future lead this version Richtofen...

Off-Season 1: "The Final Resistance"
In the alternate universe where Bogs have prevailed against the combined forces of The Therapy and the Paranormal Patrol, Ultimis Richtofen unexpectedly came as one of the first fighters in The Final Resistance. His mere presence had angered OP, and the fact he has been jobbing against The Lost only aggravated him. Well, that and him dabbing in the post-mission photo. The final nail in OP's metaphorical coffin and eleveation of his status as SETHIG  was the bonding between him and Kyoko Kirigiri, who at time was claimed to be OP 's waifu.

A bit of time later, he, Kirigiri, Raiden, Sminem, and Majima became victims to Mundus in the blacksite raid aptly named " Crypt Killer ". The Doctor himself died while trying to save Majima. (Perhaps, it could be seen to foreshadow the Cuckening of Majima, but that's a bit too much grasping at the straws.)

In the now lost recordings of the final missions, Primis Richtofen came along with the Future version of Kirigiri. But that's another story.

While his presence in The Final Resistance was brief, the events previously mentioned cemented him in the history. And the status of OP being a cuck. Still, one wonders just how things would turn had the Doctor and Kirigiri survived the Crypt...

Season 3
During his testing with the MTD, he accidentally beamed himself to U-712, where TFR takes place, and meets Primis Richtofen for the first time, although doesn't recognize him. It is believed he may have ben transported to the present along the rest of the Wrestlers and is now stuck with us.

As a result of activating the Focusing Stone, Ultimis too got transported forward in time, along with the majority of the wrestlers. Chosen Hunter, perhaps in a fit of autistic screeching, loss of his gaming buddies and lust for revenge, challenged Richtofen. And bought out the ring, for Richtofen had pinned the NEET twice to the count of 3, that had not registered somehow. Foul play, surely.

This Richtofen expresses a SETHIG hatred towards the Primis Richtofen, since he, by extent, stole his Focusing Stone. This gave way to a sort of bonding with Fred, who desired answers.

Learning of a certain Pollack being a wrestler, he immediately sought to arrange a match to dispose of him, but it seems a third party behind the shadows had his own plans for the match, as a mysterious Business Suit-wearing palid man appeared and claimed the pin on the Pollack scum for himself.

Episode 8
Attempts to loot the ruins of the TFR building but when he is attacked by a pair of robotic arms from a trunk

Episode 15
The unholy fusion of Richtofen and Samoa Joe kidnapped Red, leaving Extra and Haze a message, to come quick lest her neck gets snapped. Seems like Joe is the more dominant personality.

Episode 16
Joetofen fought Extra in a submission match, where, sharing the fate of the matches twelve years and twelve+OVA years ago, he tapped to Extra's Coquina Clutch and presumably was killed.
