The Mutant Car is a getaway car the mutants use in ThunderCats Roar.
It was briefly in use when the Fistpounder was destroyed as a getaway car. Later, it was used again after defeating Ratar-O with the ThunderCats.
It is shown to be a very simple, but oddly shaped green vehicle featuring to hands and the front and a rather high chair the driver of the vehicle sits in. It appears to only have two wheels, which also suggests it is not all that powerful and was not meant for any form of combat.
