Pumper, Dumper, and Bullseye were on Command Center 6 when they detected Cy-Kill near Galleon. They joined Command Center 14 in capturing Cy-Kill, although they suffered damages and lost one vessel in the process.
At UNECOM, Pumper and Beamer failed to stop Crasher and a squad of Renegades from sabotaging an experimental aircraft, although Pumper did manage to wing Crasher as she escaped. Later, he acted as reinforcements for Leader-1's command team as they battled a pair of animal mechs.
"Echoes and Fragments"
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.)
