Generation 1 cartoon
A member of the independent band of warriors known as the Wreckers, Moonracer helped prevent crazy people from interrupting the lighting of the well of Archon. These doomsday cultists feared taking a spark from the Well of All Sparks to ignite its twin on Cybertron's first colony world would irrevocably damage the Well itself. As a sniper for the Wreckers, Moonracer used EMP bullets to pacify these naysayers as they attempted to prevent the running of the torch from the Well to the Space bridge.
War For Cybertron Trilogy
Moonracer, Optimus, Jetfire, Hound, and Prowl enter the forbidden sector. They swerve to avoid the lightning bolts coming at them. Jetfire fires rockets to protect them from the lightning. They are now faced with metal vortexes. Prowl is sucked into one of the vortexes, forcing Jetfite to fly up and rescue him. Prowl is so grateful that Jetfire saved him that he wishes to give Jetfire the remote trigger to his brain module, but Jetfire insists that he keep it. They proceed down below to the Allspark. They suddenly find themselves surrounded by rusted old, rusted, Sparkless bots.
Moonracer, Optimus, Jetfire, Hound, and Prowl fight off the rusted Sparkless bots. Unfortunately, Moonracer is ripped apart in the battle. Optimus catches a glimpse of the Allspark above. He capture it, causing the Sparkless bots to disappear.
