- An Optimus Prime is an Autobot seemingly from some unknown portion of the Generation One continuity family.
Unicron killed an Optimus Prime from some alternate universe and sent him to the comic Unicron Trilogy universe as a warning. He died shortly thereafter.

After their own Optimus Prime disappeared, Scavenger and Smokescreen discovered an alternate version of Optimus Prime lying unconscious and barely alive in Autobase Earth. Though Red Alert did what he could, the mysterious Prime reactivated only long enough to utter a cryptic statement about the walls crumbling and the coming of chaos, then died.
Unicron later explained that he sent the alternate Optimus Prime into their universe as a "calling card", a terrifying warning of his imminent arrival. This was probably to tell the uninitiated that Unicron is a jerk.
- This alternate-universe Optimus Prime was based upon Don Figueroa's own Maraudimus Prime fan-character design.
