Kakkoi Teppodama

Kakkoi Teppodama is a villainous character from the Speed Racer film. He also makes an appearance in the PlayStation 2 version of the Videogame.

Background
Kakkoi is a Yakuza-themed Japanese racer with white hair who drives a T-180 named the "Seppuku". He's the main racing driver of Musha Motors, one of the most prestigious companies of the movie. He is featured in the Grand Prix, serving as one of the main antagonists in that race.

Grand Prix
Kakkoi is first seen shaving in the locker room, looking menacingly at Speed. He is later seen at the starting line posing for the camera, but still with his eyes locked on Racer. At the beginning of the Grand Prix race, he's only seen briefly at the Zebra Halls, where he bumps Speed as soon as he sees him, speeding away afterwards and leaving him for the other racers to deal with. Near the end, he's seen together with the Grey Ghost fighting for the top spot, before Speed arrives and joins the battle. Speed attaches the Mach 6 to the Seppuku and swings it together with the Fumée, destroying both at once. Kakkoi is saved by his Kwik-Save device.

Videogame
In the videogame, he looks notably different, having an older appearance and having black hair with a mustache. His ally is Scooter Dickey and his rival is Sweet-Tooth Jangala.

Trivia

 * Kakkoi's first name is incorrectly spelled in the Grand Prix racer list from the movie and the PS2 version of the game, as the correct spelling of his name is "Kakkoii." The game's credits spell his first name correctly.
 * "Kakkoii" is Japanese for "cool" or "handsome", while "Teppodama" is a Yakuza term which literally translates to "rifle ball", as all followers are teppodama, bullets to be fired by their boss. The bullet does not think of itself; it is simply aimed and released.
 * He is listed in the film's credits as "Yakuza Driver".
 * The reason for the striking change in his appearance between the film and the videogame is most likely because the art from the game was based on Alice Ebling's work (the person responsible for the costume illustrations). Kakkoi in her original art looks remarkably similar to the one from the game.
 * In the movie's script, Kakkoi has a removed scene where he attempts to assassinate Speed in the locker room with a razor blade, before being cut-off by Grey Ghost, who starts a conversation with Speed.
