Activate, MetalGarurumon

Summary
The DigiDestined arrive at a racetrack where they soon notice a Machmon racing around the circuit. Seeing how fast Machmon is, Gabumon is inspired to race against him, but during the race between Machmon and Garurumon, something in Machmon snaps and he turns hostile, causing Gatomon to realize this is the Digital World Grand Prix Circuit, a death race. When Machmon loses control and is going to crash, Garurumon throws himself in harm's way to protect him and is injured instead. Back at Machmon's garage, he apologizes for what happened, revealing he is the reigning champion, but the death race's old habits are hard for him to forget despite being alone on the track now. Gabumon asks to race him fair and square with only speed and no tricks, and Machmon agrees, amazed someone would want to race him without using dirty tricks like in the old death races.

The race is soon set to begin, with Mimi, Sora, Hikari, and Takeru serving as cheerleaders, Joe as announcer, and Taichi as the flagman on Komondomon. Koshiro keeps track of the competitors in case Machmon goes ballistic again, and when he does, while the other DigiDestined are angered, Machmon pleads to Yamato and Garurumon to avoid his attacks, indicating he is attacking against his will. Koshiro identifies the culprit as a Parasimon, and Machmon admits he let himself be possessed in order to protect his title and attain his maximum speed. He intends to commit suicide to prevent Parasimon from finding another victim after him, but Yamato refuses to let that happen, and WereGarurumon Sagittarius Mode tries to help, but Parasimon proves too strong, until Yamato's will to help Machmon gives WereGarurumon newfound strength to digivolve into MetalGarurumon, destroying Parasimon and saving Machmon from a fatal crash. Afterwards, Yamato, Gabumon, and Machmon finish their race, cheered on by the other DigiDestined.
