Nightmare Fuel / Macross Delta

• The Var Syndrone. Veins begin to form across the infectee's face, then the infectee begins to go completely berserk. The intro of the first episode shows pictures of the infectees rampaging.
  • What's worse is that it's actually something akin to a bioweapon used by Windermere to neutralize the opposition, and can be spread by Heinz's song.
  • As revealed in episode 7, Windemere apples and water can produce the chemicals that cause the Var Syndrome. Yes, that's right, even food can cause people to contract the Var Syndrome. Now imagine if Windemere has been exporting them to brainwash people to make it easier for them to conquer the planets that have been buying their products.
• Messer's death at the hands of Keith in Episode 10. What makes it incredibly unsettling is Keith manages to do it with such unorthodox precision by hitting him at the heart, and with such a calm expression on his face, making the crew question that it was done on purpose. Not helping is the large blood splatter on the cockpit.
• Hayate and Freyja going berserk due to the Protoculture ruins. Which is topped by Mikumo remembering some of her memories and overpowering the ruin with her singing. What's especially scary about this is that it triggered Var syndrome in the person explicitly stated to be immune to it.
• Bogue Con-Vaart. This guy's a crazy little bastard who, unlike the other Aerial Knights who are fighting to protect their homeland, just wants to kill as many humans as he can. He even tries attacking Walküre, especially whenever they're singing. Not helping is his constant smug grins and even slasher smiles he gives out often.
