Thunder Force/Nightmare Fuel

• Thunder Force V's bad ending: Cenes is subject to repeat what happened to Rynex Vasteel, only instead of ejecting from the ship, she is trapped in it.
• The good ending as well. While heartwarming music plays, the Last Letter scene is still a bit spooky.
• Enemy/boss design in the games are often pretty Nightmare Fuel-y too, like the Evil Core in Thunder Force IV's eighth stage—a putrescent-looking thing that's served by little white flies that explode. And in its final phase (where a single giant fly is carrying it around), it basically drools its attacks out.
• The ORN Emperor in Thunder Force VI.
  • The Easy Mode ending as well. It consists of a dark screen of flashing images and the eyes of the ORN Emperor while ominous chanting in the background is heard as ORN Faust calls for Earth's unconditional surrender using a darker version of The Guardian's speech from Thunder Force V.
