"'Til all are one" is a phrase knit throughout Transformers mythology and legend, often used as a rallying cry by the Autobots. It has been interpreted as meaning either until the end of the Great War, when the Transformers will shed their adversarial factional affiliations and all are one united group, or until all Transformers sparks are united in the Allspark of Primus. It is a hopeful slogan, a call for future unity.
