Fiction

Dreamwave Armada comic

The Optimus Prime and Prowl of Viron 1103.12 Gamma were visible through a space bridge portal in Aurex 402.24 Gamma. Worlds Collide, Part 4 of 4

Ask Vector Prime

In this universe, Optimus Prime (and thus Scourge) were female Transformers but more importantly, the thirteen Autobots on Earth were all Spychangers. When Sky-Byte accidentally made all of Earth's energon toxic, Optimus had her troops downsize. Daytonus and X-Brawn blew up the Predacons' stockpiles of clean energon in response. The war ground to a halt as the villains ran out of power, with only Scourge being able to convert to a Spychanger body. Ask Vector Prime, 2015/08/18

Universe comic

Optimus Prime, Prowl, Ultra Magnus, and Ironhide were dragged out of their timeline into the Universe War, and Reptilion attempted to "recruit" them for Unicron. Instead, the Autobots fought back: Optimus took control of her troops, other abductees, and the arriving Children of Primus, driving the enemy back. Voice Actor Drama

Notes

"Remember us? No? Well we don't remember you, jerk."

• Viron 1103.12 Gamma is the home universal stream of the Universe versions of the Robots in Disguise Spychangers. Its designation is derived from the release date of "Worlds Collide, Part 4 of 4", in which a Robots in Disguise universe, retroactively identified as this one, was glimpsed through a space bridge portal.
• Optimus and Scourge are female as the former was voiced by fan Michelle Irby for the OTFCC 2004 stage show.
• The Autobots are specifically said to be "thirteen" in Ask Vector Prime. That's the exact number of Spychangers in the Robots in Disguise line!
