Nightmare Fuel / Digimon Xros Wars: The Young Hunters Who Leapt Through Time

• The state of Blossomon's victims after he drains them in episode four. Seriously. They just wither into husks as if they were plants themselves.
• This may be intentional or not, but Dracumon's evolution to Yaksamon shows him ripping his own face off.
• Sephirotmon was just plain creepy. The scene where laughing children appeared from inside his mouth didn't help.
• While he doesn't really do much in the long run and the destruction he does is easily reversible, it doesn't change how horrifying Quartzmon really is, simply because very few Digimon villains play to his level. It can catch you off guard if you aren't expecting it.
  • Quartzmon is a genuinely disturbing Digimon. Its main body is a slimy, chalk-white D-Reaper-esque mess with multiple arms, a mask with six eyes and a large Belly Mouth. It's difficult to believe that this thing is a Digimon and not some Angel from Neon Genesis Evangelion — at least Millenniumon and Diablomon look like Digimon unlike this thing. He also converts entire portions of the human world into DigiQuartz and moves onto taking over the world instantly when he's fully manifested. If you ask a Japanese fan they'll tell you this guy is just as bad as the D-Reaper and it's for good reason.
  • The reveal that he is is Astamon all along. Just how long is he within the Hunter's group?? Also after that reveal, he opens his Belly Mouth to reveal the numerous Digimon victims he absorbed, all of them which are writhing in pain.
  • He's one of the few villains who merrily attempt a Hostage Situation against The Hero by showing the faces of the numerous people he absorbed in obvious And I Must Scream situations, and dares if Tagiru were to hit him, he could say goodbye to everyone else. The way he does it is just hardcore Body Horror; he extends his limbs in a tree-like fashion and the faces of his victims appear on each "branch", aware that they are being absorbed but can't do anything against it. He shows more when Tagiru and Arresterdramon gets close to his core.
  • Just how he literally managed to Take Over the World. It doesn't last long, but Digimon villains who attempt to take over the world are usually stopped short before they manage it. This guy isn't one of these cases and by the point Tagiru fights him he's the last man standing.
