During the war, Megatron attempted to cripple the Autobot war effort by staging a commando strike on the Iacon Energon Refinery. He led a team of five into the refinery, only to find that Optimus Prime had anticipated the attack and set up defences. The Decepticons walked straight into a trap and were pinned down by Autobot fire. After the other three team members fell, Megatron caused a distraction by shooting some of the Autobot gunners while Soundwave went to plant the last bomb. Soundwave was injured, and Megatron mounted a rescue mission of his own. Optimus's surprise at his opposite's compassion caused him to hesitate, and Megatron set off the solitary bomb they'd planted, allowing the Decepticons to escape.
