Powertrain is the cautious, by-the-book leader of the Off Road Patrol. He approaches every problem with patience, carefully analyzing the best way to tackle it, be it interpersonal conflicts within the Autobot ranks (particularly with the standoffish Mudslinger) or sneaking into a Decepticon installation to blow it to kingdom come from within. Thankfully, he's also a pragmatist, and knows that sometimes, "by-the-book" isn't the answer, no matter how uncomfortable such a decision makes him.
