Working undercover as a tow truck, Tow-Line (Wrecker Hook in Japan) has learned the rules of the road, and now lives by them, punishing any infraction, large or small, and even if a fellow Autobot responsible is responsible. He is well known for the phrase "No parking means no parking!" He's responsible for traffic riot control, and can use his powerful hook to lift and carry anything from a car to a bullet train.
