Hagurumon

Hagurumon is a Digimon in the mobile game Digimon ReArise.

A mutant Machine Digimon shaped like a gear, Its inner workings are composed of countless gears in constant motion. If even one is missing, the gears will stop and vital functions will cease. It possesses the special ability to infect its opponents with a computer virus to manipulate them as it sees fit. This ability leads other fiendish Digimon to try and exploit Hagurumon to their advantage. Since it lacks self-awareness, it doesn't even know its powers are being abused. Its special move, Cog Crusher, buries a virus-loaded black gear into its enemy, driving them mad.
