Nightmare Fuel: RAY Series
- The major Big Bad of the series, the Con-Human super-computer from RayForce and it's prequel RayCrisis, almost single-handedly wipes out all of humanity when it started to malfunction. The manual of RayForce's PC port describes all the horrors it caused on Earth; it caused natural disasters with the planet's weather-control unit, gone completely rogue, deprived the Earth of it's oxygen to suit it's own needs, and created temperatures that made the planet uninhabitable while killing off those unfortunate enough to live on Earth. After taking over the Earth, all of humanity that managed to escape from the planet was only left with one option: Commence "Operation: RAYFORCE" and destroy the Earth. The way it turned bad? It was hooked up to a cloned human — and somehow came to the conclusion that fresh clones were superior to normally born... not just humans, but pre-existing life in general. The worst part: It was a MAN-MADE SUPER-COMPUTER.
- The Extra Mode ending of RayStorm is no better. Over 70% of the seven-billion inhabitants of the planet Secilia were killed during "Operation: RAYSTORM" while the remaining 30% would have no chance of survival. Working Designs' translation of the ending in the PlayStation version is much worse than the translation in the HD version.
- "Molecular Clock" (Original ZUNATA version), the boss music for the sixth and seventh stages from RayStorm, can be a very unsettling song.
