A mysterious new trio of transforming robots appears and quickly runs roughshod across the swamplands and farmlands of Indonesia. A distress call reaches Teletraan I and a team of Autobots, including Skyfire, Brawn, and Windcharger, travel to Bali to address the situation. Close behind are the Decepticons, who have also detected the presence of the giant robotic insects, soon to be known as Insecticons. Deep in Demon Swamp, they find an escape module jettisoned shortly before the Autobots and the Decepticons crashed on Earth. Meanwhile, Optimus Prime and other Autobots meet with many obstacles trying to regroup with Skyfire's bunch, who engage the Insecticons in an energetic fight in a corn field. The skirmish briefly pauses as the Decepticons arrive and introduce themselves to the Insecticons, whereupon they combine forces against the Autobots, immensely fortified by dozens of Insecticon clones created from wrecked farm machines and controlled by Insecticon Shrapnel. As Optimus's group arrives, the Decepticons leave to concentrate their attention on an oil refinery while the Insecticons take on the Autobots. The battle eventually moves to the oil refinery, where Shrapnel displays a wide range of fighting skills, the most impressive and dangerous one being his ability to harness lightning in a most devastating way. However, the Autobots protect themselves by staying in vehicular mode, their rubber tires insulating them from Shrapnel's assaults. Optimus Prime stops Megatron from blowing up the refinery while Trailbreaker uses his force field to cut off Shrapnel's clone control, saving Bumblebee and Spike in the nick of time. The Insecticons finally reveal their self-serving ways as they devour the collected energon and run off with the Decepticons in hot pursuit.
