Trivia

 * Super Custom YO649Z Mk. II is the first anime only villain to appear in the series.
 * The anime design for Custom is believed to be based on a Toyota Celica A20 with an elongated tailfin and bumper. His rectangular quad headlamps, however, differ from the round headlamps of the original vehicle's. Custom's coke bottle design traits are reminiscent of the car as seen from the sketches.
