As firemen battle a raging blaze in Scramble City, a new fire vehicle hauls up. When one of the firemen approaches it, a voice makes a dry remark about the accuracy of the name "fireman", before fire arcs from the truck's roof-mounted weapon to the burning building. The new truck transforms into Smolder, with his Mini-Con companion Chopster, who are determined to put the city to the flame.

Luckily Bumblebee and Ratchet have been alerted to the duo's activities by Optimus Prime, who briefs them as they race through the streets. They reach the burning building and are confronted by Chopster, who looks ready to fight them. As soon as Bumblebee lowers his battle mask, the Mini-Con screams loudly and runs back into the building. While Bumblebee is keen to avoid a fight, a moment later Smolder almost runs them down, and sprays Bumblebee with flame.

Ratchet blasts Chopster from Smolder's roof with an EMP pulse, and the Mini-Con falls to the ground in ax mode. Smolder flings him at the Autobots, but Bumblebee bats the projectile aside, and suggests Ratchet disable the larger Decepticon with another pulse. Unfortunately Ratchet's weapon needs time to recharge, and while Bumblebee and Smolder fight, he uses his own spark to give it enough power. The EMP blast locks Smolder mid-transform, and the two Autobots crack jokes over his body.
