Kabuto's Ninjas are Kabuto's henchcars.
Ninjas appear when summoned by their leader, Kabuto, to attack Mater, surrounding him. When Lightning is brought into the story, as "Dragon Lightning McQueen", he fends off the ninjas. In the end, they laugh at their own boss after he got stripped of his modifications, and joined Mater's party.
In Kinect Rush: A Disney/Pixar Adventure, the ninjas appear in the second level when the player unlocks a new goal, which the player has to knock them out to prevent them causing any trouble, and to score points.
Each ninja is painted a reflective metallic blue, with gray rims, though they appear green as they have a light under them. They wear white and red headbands.
