Quartzmon

Quartzmon is an Unidentified Digimon. It is a colossal Digimon that continues to absorb data and amplify its power. The large wicked globe that corresponds to the majority of its body is a fusion reactor that generates Quartzmon's power source, the "Gyuputo particles", from the data it absorbed. Quartzmon's true body is at the top, and can act away from the large wicked globe, and it's also possible for it to change its form. It has a greed for the data of the entire world, and completely swallows and absorbs Digimon and humans.
