Quartzmon
Quartzmon is an Unidentified Digimon—a massive creature that's basically a walking data vacuum. The thing keeps absorbing information and growing stronger, which is exactly as terrifying as it sounds.
Most of its body is taken up by a huge, wicked-looking sphere that functions as a fusion reactor. That's where the magic happens: the reactor converts absorbed data into "Gyuputo particles," which fuel Quartzmon's entire operation. But here's the weird part—its actual true body sits on top of that giant orb, separate from it. It can move independently and even shift forms entirely.
As for personality, Quartzmon is basically unstoppable hunger incarnate. It's obsessed with devouring every last bit of data on the planet, indiscriminately swallowing up both Digimon and humans without hesitation. The more it absorbs, the more powerful it becomes, which makes it a genuinely horrifying threat.
