Kevin Levin's car is a Green Muscle car that he drives around with Ben and his team of Plumber's Kids.
His car makes it's first appearance in Ben 10 Returns (1) and has since then, appeared in every episode. He absorbs its material in the episode "What Are Little Girls Made Of?" during a fight with Verdona which made him turn into green plastic. Kevin Levin's car has aged in "Paradox", but instead of the green and black color, it is a brownish-red and black car. Paradox later gave him a new car. His car is destroyed again by Manny in "Plumber's Helpers".
