Quartzmon is the primary antagonist in the third season of Digimon Fusion, The Young Hunters Who Leapt Through Time. He is the creator of DigiQuartz.
In the aftermath of the Xros Heart United Army's battle with DarknessBagramon, Quartzmon was created when the remnants of the evil emperor's data combined with the digital network of the Human World. He is able to generate the DigiQuartz, which he uses to lure in Digimon and feed on their data. In order to absorb the entire Human World into the DigiQuartz, he offers Ryouma Mogami the opportunity to surpass Taiki Kudou, subverting the Old Clock Shop Man's plan to gather six legendary heroes and use the Brave Snatcher against the monster.
