Primal Essence

The Primal Essence is something that Transformers swear by.

Fiction

Marvel Generation 1 comics

Dogfight, after seeing a Vrobian outside the window, screamed: "By the Primal Essence!" Kings of the Wild Frontier.

Coming face to face with the Matrixspawn for the first time, one of the Transformers at VsQs cried: "By the Primal Essence!" Dark Creation

Notes

• One would think the Primal Essence to have some connection to the Dark Essence, Unicron's "soul". Simon Furman came up with both concepts.
