Kabuto's ninjas are in the Cars Toon Tokyo Mater.
In Tokyo Mater
They are first seen when Kabuto summons his ninjas to defeat Mater, they spread out their wheels to attack. Then Lightning Dragon Mcqueen comes to the rescue to defeat them by using his wheels to throw them out of the streets. Lastly, they are seen laughing at Kabuto in his stripped form much to the rule of the loser who will have stripped modification which will become stock.
