Tokyo MaterKabuto's grudge against Mater started when Mater accidentally ran into him after towing Ito San to Tokyo. After becoming extremely angry with Mater, Kabuto challenged the tow truck to a drift race. He tells Mater that he must race him to the top of Tokyo Tower, and whoever reaches there first will be crowned "King of all Drift Racers." He also tells him that the loser will be stripped of all modifications and become "stock." When the race begins, Kabuto tries to cheat his way to victory by constantly pushing Mater off the road, and when that doesn't work, he summons his ninjas to attack Mater. Fortunately, the ninjas are all defeated by Dragon Lightning McQueen, but it turns out to be a distraction so that Kabuto will reach the tower first. When Mater is launched into the air by McQueen and lands on the very road leading up the tower, Kabuto becomes furious and pushes Mater off the balcony, but Mater uses his winch to get back up and reaches the finish line at the top of the tower. In the end Kabuto loses and as a result he is stripped of his modifications and is ended up being laughed at by his own ninjas and the other cars.
Kabuto is seen with all his known modifications, despite Tokyo Mater ended with him losing all of them. This may be seen as a proof that the events of Mater's tale were made-up and never happened. It can be noted that the Cars Toons episode in question is the only in which Mater fails to prove efficiently the reality of his story. However, other suggestions include that it could be another car that looks like Kabuto or that he got his modifications back after the story if it did happen.
- He was designed to resemble Boost.
- Kabuto is the name of the traditional Samurai helmet.
- Kabuto had green eyes in Tokyo Mater, but in Cars 2, his eyes are brown. It may be possible that Kabuto was wearing green contacts in Tokyo Mater, and that being of Asian origin, brown is actually his normal eye color. His Cars 2 die-cast does not take this difference into account, and still has green eyes.
