"Echoes and Fragments"[edit]

In an unstable hybrid universe that incorporated both GoBots and Transformers, Pumper was aboard a Guardian shuttle bound for Earth when Megatron attacked and hijacked the ship. The Decepticons executed him while seizing the ship.

(Pumper only suffered this fate retroactively due to the machinations of Sideways and Gong. When the events actually took place in this hybrid timeline, it was an Autobot crew who were attacked by Renegades.) Echoes and Fragments
