Feeling that the conquest of a new planet was needed, Bludgeon chose at random the planet Klo. With its primitive and peaceful carbon-based populace, there was little question who would win. Within a day, most of the planet was under Decepticon control, for all intents and purposes.
Autobot leader Grimlock had forseen such trickery, and had already taken measures. Firstly, he had a tracking device onboard one of the Decepticon ships, and secondly, he was able to get hold of a number of old Decepticon cruisers that still functioned. Gathering the Autobot army, he headed for Klo.
The Decepticons, meanwhile, had found Grimlock's bug, and set a trap for him. The trap worked perfectly, and Grimlock found himself fighting for his life with the few Autobots who survived the initial ambush. At this time, a ship arrived at the planet. Much to everyone's surprise, formerly deceased leader Optimus Prime jumped out. Though he claimed to have been resurrected by an entity known as the Last Autobot, Bludgeon refused to believe him and ordered his troops to attack. At this point, the Last Autobot began resurrecting more Autobots, forcing Bludgeon to face the fact that he could never win. Conceding this, he ordered his troops off of Klo and vowed to place themselves in exile.
