Nightmare Fuel / Chaotic

• The Blight, a giant green glob that attacks randomly in Prexxor Chasm and all its inhabitants are terrified of it introduced in "Chasm Quest". It first appears during a match Tom and Peyton are having and they're stunned by it as it is immune to all their attacks. Tom realizes why Smildon wanted to use his Scanner to leave as it will always attack and nothing can stand in its way as Attacks, Gear, or Mugic have no effect on it. At the end of the episode, Katz brings up the possibility that Smildon might not have even survived The Blight, and the final scene shows Smildon cowering in fear as The Blight appears. The episode it first appears in ends with Smildon hearing it approaching. Things get worse in the follow-up episode. Where the Blight's gotten huge, and Prexxor Chasm looks almost completely devastated.
  • What makes it scarier is that it's never explained what the Blight even is. It's definitely not a Creature, because Creatures don't show up in Location scans, and it seems to be immune to every attack and Mugic anyone can throw at it. It's somehow part of Prexxor Chasm on a fundamental enough level to be part of the Location scan itself. The only explanation is that Prexxor Chasm itself has some kind of disease. In "Blight Fight" it's also revealed that Overworld locations like the Chasm tend to have Caretakers, but no one knows who the Chasm's is. What happened to them? Did the Blight kill them? Or is their absence the reason the Blight was able to form in the first place? So much of the Blight is made scarier because nothing about it is ever explained, yet it breaks all the rules of the setting.
• Cromaxx, Maxxor's ancient ancestor. Unlike Maxxor, Cromaxx is a wild and savage brute that has no restraint and who will stop at nothing to destroy anything in his path and is just as strong as him and will attempt to destroy anything he percieves is an enemy. Which is everything.
• From "A Fearsome Fate", the hallucinations that Maxxor/Tom experience due to Maxxor's drained courage stat are both this in universe and out of universe. They make even Intress and Cerbie scary!
  • It gets worse when Tom and Najarin find out that it's actually the work of a Mugic that Van Bloot cast that not only drains Maxxor of his courage, but also his strength, speed, and wisdom and what the victim loses, the caster will gain.
• One of the traps in "Gigantempopolis" is a statue that brainwashes people into walking into a laser.
• While the "curse" in "The Curse of Kor-bek" turned out to be nothing more than the greed of Captain Kor-bek and his men, their fate still seems rather nasty. Imagine being paralyzed for the rest of your life, which since you're not getting any food or water will be cut rather short. Also remember a victim of the Song of Stasis mugic can still move their eyes...
• Some of the creatures' designs can be pretty creepy. For example, all of the M'arrillians, the Overworlders Skulk and Hifdan, most Danians that use infection effects, and finally the card art of Swassa, although she's perfectly normal in the show during "Chaor's Commandos".
• The Danian Parasite is extremely terrifying. What is a relatively niche effect in the card game, is a truly disturbing case of Body Horror in the show. It is a painful process that not only changes a creature's species, but completely alters their allegiance to the Danian Hivemind. Tom having scanned Raznus after he'd been infected actually mutates during a match, and the process is NOT a pretty sight to say the least!
