Depth Charge was once the security officer on the Maximal colony of Omicron. He was a dedicated Maximal who was loyal to his duties. That all changed when a Maximal experiment named Protoform X destroyed the colony, leaving Depth Charge as the colony's sole survivor. From that day on Depth Charge advocated the destruction of Protoform X, trying to track him down across the galaxy.
Depth Charge did eventually capture Protoform X and advocated his destruction, but the High Council of Maximals and Optimus Primal refused, insisting on banishing Protoform X instead. Depth Charge pursued Protoform X relentlessly from that day on, swearing to destroy him.
Depth Charge would encounter Protoform X once again when he was taken to Earth's past by a time vortex. In the process he became a transmetal and gained his new transmetal form. His first goal was to track down Protoform X who had renamed himself Rampage. The two fought almost immediately upon Depth Charge's arrival, the feelings on both sides as bitter as ever.
At first, Depth Charge was reluctant to aid the Maximals, but eventually sacrificed himself in an effort to destroy the Decepticon starship Nemesis. He did not succeed in destroying Nemesis, but he and Ramage did have their final confrontation near the great ship. Ultimately, the two destroyed each other, bringing their long circle of violence to an end.
