Jayce and the Wheeled Warriors 1985

The Lightning League drives white and silver vehicles with assorted weaponry, and are led by a teenager named Jayce. The villains are organic green vegetable-based creatures called the Monster Minds, who tend to take the shape of black and green vehicles. They travel via large green organic vines which can grow in and across interstellar space, and sprout seeds that rapidly grow into further Monster Minds. They are led by Saw Boss.
