Fiction
IDW Generation 1 continuity
Dominus authored a work called The Ascetic Cybertronian, in which he wrote, "Pleasure is a distraction from pursuit of truth." Omega's Conundrum
Before the war, Dominus spearheaded the movement to recognize the rights of the so-called "disposable class". He was inspired by his strong friendship with Rewind, whom he employed as a data receptacle. He would secretly give Rewind some of his own premium energon, instead of leaving him to feed off the cruder stuff society said he was supposed to use.
The two shared the closest of bonds and became Conjunx Endurae.Words Hang in the Air Together they went off searching for Luna 1, which they believed held a cure for cybercrosis. They returned empty-handed to find war had broken out, and they quickly chose to become Autobots.
Some time later, Dominus mysteriously vanished. Rewind began a lifelong quest to find his whereabouts. Before & After
The Functionist Universe

When Brainstorm altered the timeline, he created a Cybertron where the Functionist Council had slowly but surely conquered the planet. In this timeline, Dominus failed to end the disposable class and could only pull strings to get Rewind upgraded from disposable to research assistant. He also removed Rewind's obsolence chip, ensuring he couldn't be "recalled" if the Council turned on memory sticks. The two acted against the monstrous dictatorship both secretly and verbally, which got Dominus turned into a "flathead": his head replaced with a computer screen that was Council property, given no voice and 'talking' with text so he couldn't express himself, and his face showing propaganda pop-ups at random moments. He continued to resist and reached out to his spark-brother Minimus Ambus, but the Council found him out.
In an act of supreme cruelty, the Council deleted Dominus' vocabulary so he only knew the simplest of words and "love" was not among them. His screen was then used to taunt Rewind and Minimus about their impending doom. The Custom-Made Now
Notes
- "Dominus" means "lord" or "master" in Latin, while "Ambus" appears to be derived from "ambulare", meaning "to walk".
- Members of the House Of Ambus all have those distinct 'taches.
- In "Into the Abyss" Ultra Magnus refers to the Ambus Test, a universally recognised question-set designed to detect sentience in mechanical lifeforms that was presumably named after Dominus.
