KO Cruiser is one of the five Monster Minds that appear in Jayce & The Wheeled Warriors. Like the others, KO Cruiser has both a humanoid form and a vehicular form. He does not participate in battle directly, instead directing his many clones against the Lightning League.
The humanoid KO Cruiser is the tallest Monster Mind after Beast Walker. He has vines growing from his scalp and running down the back of his neck and a vine for a right arm that is always gripping a large green ball. In vehicle form, KO Cruiser resembles a weaponized pickup truck with an angry face, his headlights resembling frowning eyes and the radiator vent appearing to be a mouth filled with large square teeth. His armaments include the large vine ending in a ball which is used for smashing enemies and laser guns on either side of the body.
