Hagurumon is a Machine Digimon whose name and design are derived from the gear (歯車 Haguruma?). It is a mutant Digimon shaped like a gear. There are countless gears built into its body, and the gears are constantly rotating. For that reason, if even a single gear is missing, all of the gears in its body stop rotating, and it becomes unable to maintain its vital functions. Hagurumon possesses the special ability to send a computer virus to its opponents in order to manipulate them at will, and that ability is exploited by fiendish Digimon. However, because Hagurumon itself doesn't have any sense of self, it doesn't even know it is being misused.
Digimon Adventure 02
A Hagurumon is among the many Digimon seen during the final battle against MaloMyotismon.
A Hagurumon works alongside a Clockmon on a clockwork cloud plain. When Rika Nonaka, Renamon, Kazu Shioda, and Kenta Kitagawa end up on their turf and stumble upon a jammed clock, Clockmon's warning comes too late and Megadramon emerges from his prison. Clockmon and Hagurumon learn that Renamon went to the Real World as she fights Megadramon as Kyubimon, and Hagurumon expresses his own desire to digivolve right before Kyubimon's Fox Tail Inferno attack is deflected at Hagurumon, knocking out one of his gears. When Kyubimon is taken down by him, the Legendary Tamer Ryo Akiyama and Cyberdramon appear and bring down Megadramon. Ryo replaces Hagurumon's gear, and Clockmon and Hagurumon heap praise upon him. Hagurumon wonders when he will go to the Real World and get a Tamer. Later on, when Calumon unleashes his Shining Digivolution power, Clockmon and Hagurumon are affected.

Hagurumon's face is seen as the left eye of the robot. In this form, Hagurumon can regenerate its hand. Michelle is rescued by Keenan Crier. Hagurumon is destroyed by RizeGreymon, causing the toy robot to return to normal.
