Thunder Force/Nightmare Fuel


 * Thunder Force V's bad ending:.
 * 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.
