Administrator Cere
The left half of Administrator Cere's brain, inheriting his original body and name. As a mad-science experiment and excuse to effectively spread out the work, Administrator Cere attempted a bold procedure on his own brain. He split his brain down the middle, inserting the right half into another body. Each half had a magitech chip attached to make up for the missing half, as well as to allow the halves to mentally communicate when necessary. This created two versions of himself, one logical and detail focused and another more personable and fun. Either way, the experiment was a success, even if it dropped their individual intelligences.
Appearance
Domed Unicorn with a gray coat, wearing a Stable 83 suit and Pip-Buck with a stack of papers on his flank. His dome only has half a gray-colored brain in it with the rest of the space filled with vacuum-tube-laden computer chips.
Personality
Cere is a more serious and detail-oriented pony compared to the other half of his brain. He speaks well enough, but has difficulty making any complicated decisions if he's too far away from Bellum. He also finds humor to be tricky since the missing half would handle that.

Bit Shift
Bit hails from Stable 45 which was designed to have two major sections; one residential like a normal Stable, and one that was entirely state of the art laboratories. Mixed into the general population were many of Equestria's brightest, given free reign to pursue whatever research they wished within the Stable with little to no oversight. Over time, the experiments and research being conducted grew more and more unsavory for the general populace, leading to rising tensions and conflict. To stem the impending danger that the Overmare might put a stop to their activities, which had by this point progressed to foalnapping dwellers for experimentation, a group of biologists and cyberneticists dug up the schematics for the Cyberdog and planned on using the same tech on the residents, thereby creating a small army to overthrow the Overmare and establish total control over the Stable. Bit, a pony specializing in maintenance of the Stable's computerized systems, was one of the unlucky few to be selected for the procedure.
The chosen ponies were knocked out and taken to the operating table to have the signature domes installed and enchanted. Thankfully, before they could finalize and activate the mind control spells the ponies broke free and fled, with Bit stealing a beam pistol from one of the scientists. Fearing they'd eventually be recaptured and forced to serve the scientists, they left the Stable and dispersed across the Wastes. 
Appearance
Blue Unicorn with a scarlet tail, magic, and eyes, but no mane. His brain matches his coat color. He wears his Stable Suit and a Pipbuck on his left foreleg, and is often seen carrying a beam pistol.
Personality
Hash is a bit timid in this new world and is especially wary of anypony trying to get at his brain after the forced experiment on him. He is slowly warming to the idea of brainplay, however.
