"'Til all are one" is a phrase knit through Transformers mythology and legend, often used as a rallying cry by the Autobots. It's been translated as either until the end of the Great War, when all Transformers shed their factional affiliations, or until all are rejoined into the Allspark of Primus.

While Chromedome probed Overlord's memories, he inserted a "Trepan's Trigger", altering the Decepticon's memories so that the phrase was associated with all his past defeats. Later, when Rodimus inevitably said it while being choked by Overlord, the phrase triggered Overlord's pathological fear of defeat and immobilized him. The crew was able to force Overlord into his slow cell and Chromedome launched the cell into space and destroyed it. Remembrance DayUnder Cold Blue Stars

Notes
- The phrase has its roots in early script drafts of The Transformers: The Movie. Rather than feature the Matrix of Leadership, early versions of the movie's story instead had "Life Sparks", Transformer life-forces very similar to the sparks that would later be introduced in Beast Wars. Upon his death, Prime transfers his own Life Spark to Ultra Magnus, and then utters a prototypical version of the phrase clearly derived from this practise: "Til all Life Sparks are one!" The original intent of the phrase, then, was clearly to reference a time when all Transformer life had ceased and become one in the afterlife, long before the idea of a singular afterlife for the entire race was independently created by other writers.
