Fiction

IDW comics continuity

"With Lost Light Insurance, you can combine your life and your generator policies."
"That's great, I JUST combined them!"

The Duobots, Shock and Ore, were present aboard the Lost Light when it left Cybertron. Ore was standing next to the quantum generator when it failed, which resulted in him being fused into the generator itself. Brainstorm remarked that, on the bright side, at least now they'd know which Duobot was which. Liars, A to D Part 2: Hangers On‎

Notes

Presumably, the Duobots were created as an Autobot counterpart to the Duocons.
