Cold-blooded and obsessed with efficiency, Ratbat's primary concern is looking out for himself. He treats his responsibilities, whether as a fuel auditor or as leader of Decepticons, as a business. In his book, everything comes down to profit and loss. In his role as fuel scout, Ratbat carries sensors that allow him to detect and evaluate the quality of fuels of various types, from primitive hydrocarbons to energon. He can process any number of these different fuels to power himself.
