Proganomon

A turtle-like Mineral Digimon that primarily inhabits desert regions. Proganomon uses its drills as excavators to penetrate through bedrock as it travels. As it does so, it triggers earthquakes that hollow the earth and collapse the surface. At night, it retracts its hind legs into its shell, then expels the sand and gravel stored in its body to travel long distances in search of a safe place to sleep. Proganomon's shell constitutes more than half the volume of its body, and comprises mostly mineral data. As a result, whenever a Proganomon is destroyed, all that remains is a fossil-like shell. The left-behind shell will sometimes become home to Digimon inhabiting sandy areas. Proganomon's special moves are Tricone Bit Demolisher, during which it rapidly revolves its claws to grind its opponent's armor to dust, and Drill Emission, where it launches drill-like missiles from its shell.
