History NightmareFuel / MetroidDread

** Raven Beak's character is best described as [[EvilCounterpart an evil version of Gray Voice]]. Like Gray Voice, he is technically Samus' genetic father and showcases a far less benevolent side to the Chozo. But unlike Gray Voice, his personality is a hybrid of Mother Brain's megalomania and Ridley's sadism. He claims he's going to bring order to the galaxy ForTheGreaterGood, but doesn't seem to care about his people's plight with the X Parasites, and it's heavily implied [[NotSoWellIntentionedExtremist he's only in it for the thrill of conquest]]. He is exactly what Samus feared Gray Voice was in ''Manga/MetroidManga''.

** First, there's the [[https://www.youtube.com/watch?v=RH1KZgFC4NA Patrol Theme]], which sounds rather... empty, like you've entered some unnatural place within ZDR. The AsceticAesthetic is emphasized, as the robots' patrol zones are all clearly artificial areas solely for the purpose of being where an E.M.M.I. lurks and searches for Samus. It combines with the unsettling chirping noises the robots make to make the message clear: you're in the E.M.M.I.'s territory now. ''Tread carefully.''
** When/if an E.M.M.I. detects your presence but hasn't seen you yet, [[https://www.youtube.com/watch?v=5m1WfUrt2gs the Search Theme]] kicks in. It has elements of the Patrol Theme, but given a substantially more tense variation, drilling in the idea that this SuperPersistentPredator knows you're close and is heading your way.
** And finally, [[https://www.youtube.com/watch?v=3_puJwNY4gM the Chase Theme]] for when an E.M.M.I. spots you and begins to hunt you down in earnest. It's frantic and energetic, incorporating what sounds like alarm sirens to match a player's [[OhCrap likely thought process]] as they realize the KillerRobot has seen them and is closing in for the kill. The tension doesn't let up even when you have the Omega Cannon, as now you have to whittle the faceplate away with the Omega Stream before prepping a blast to the eye. All while the E.M.M.I. slowly makes its way to you, where either it dies, or you do.

* The opening cutscene features a recap of events of Metroid Fusion. This includes a high definition recreation of the introduction of SA-X (the scene which provided the page image for that game's own Nightmare Fuel page).

* One of Samus’ old enemies, Kraid, is revealed to have survived the destruction of Zebes in ''Super Metroid'', albeit now serving as Raven Beak’s captive slave/pet. And given the physical condition he’s in when Samus encounters him on Cataris, he may have [[FateWorseThanDeath genuinely been better off dead]]. His usually obese frame seems thinner as if he were famished, and much of his body is now riddled with scars and rotting tissue due to Raven Beak torturing him as seen in the gallery. His neck has become swollen to the point where he struggles to vomit projectiles with the tight restraining collar placed on him. Then there is Kraid’s middle stomach hole [[BodyHorror which is shown suffering some sort of infection/infestation, oozing purple pus and blood while shooting out rolling globules of toxic fluid]]. The spikes Kraid shoots from his stomach now appear as gross, twisted chunks of splintered bone thanks to the modern visuals.
