Fiction
Fall of Cybertron comics

Shortly before the Great Exodus, Sludge was a member of the Lightning Strike Coalition, a brutal subgroup of Autobots under the leadership of Grimlock, who reluctantly followed Optimus Prime's more cautious brand of warfare... when ordered. Swoop was sent to investigate Shockwave's energon sources but he worryingly disappeared. When the other four coalition members learned that Swoop had been captured by Shockwave, they disobeyed orders and went after him themselves. Good Intentions Sludge and the others followed Grimlock, secure in his arrogance, who was glad that the fate of Cybertron rested in their hands. Secrets

Sludge and the rest of the Lightning Strike Coalition deserted their posts defending the Ark to look into some mysterious energy readings. He helped steal an Autobot drop ship and together the team traveled to the Sea of Rust. Unfortunately the energy readings related to Shockwave's recent activities near the energon lake, particularly his efforts on the space bridge and the creation of the Insecticons. The Lightning Strike Coalition battled the Insecticons, but while the others were captured for Shockwave's continued experiments, Sludge was in stasis lock. His body was found by Jazz, partially dismembered and grafted to the wall of an Insecticon hive. Jazz stated that he was in deep stasis. Jazz removed Sludge's memory core while attempting to find out what had happened in the tunnels. Jazz later flooded the tunnels with a highly toxic fluid, quite possibly destroying Sludge's body in the process, But there is a chance that he is still alive even if the tunnel blew up.
After escaping from captivity, the newly christened Dinobots found a hologramatic datacore which projected the body Shockwave had originally planned to give Sludge.Fall of Cybertron
