History NightmareFuel / MegaManX

** The [[BossWarningSiren "Warning" message]] that made its debut in this game. You have the word written across the screen in huge red futuristic letters whenever you enter into a boss battle and that it flashes constantly upon sight with a scary alarm sound before disappearing. Most people who saw it were quite scared of it as they didn't expect for something like it to occur so suddenly and to add more horror to its nightmare potential, most of the boss battles from within ''X4'' and beyond had took place from within obscure and solitude places that were quite dark and unnerving (given the UsefulNotes/PlayStation's darker and sharper graphics). To add even more horror to the "Warning" message's nightmare potential, think back to the first Final Weapon stage of ''X4'' and remember on how both X and Zero had surprisingly ran into both Double and Iris (who at the time were seen as cheerful characters from within a relatively dark game like ''X4'') from within their separate in-game scenarios. When the "Warning" message had instantly flashed from within the room of where the sudden confrontations had took place from, you immediately knew and realized that [[BitchInSheepsClothing Double]] and [[BewareTheNiceOnes Iris]] weren't there to help you out.

** ''[[https://www.youtube.com/watch?v=UXUmCW0zMBo Soul Asylum,]]'' used for the [[BossRush teleporter room]] in Crimson Palace, is certainly one of the most disturbing themes in the entire ''X'' series. The eerie, distorted effects and [[OminousMusicBoxTune broken music box-like tunes]] in the track are almost hypnotic, and the fact the room is designed to look like a Reploid graveyard -- with each teleporter resembling a decaying tombstone -- makes it so much worse. [[TearJerker One can only imagine]] what must be going through Axl's mind when [[FightingYourFriend he has to kill his adoptive family all over again]] in a setting like ''that''.

-->'''Flame Hyenard:''' (''wailing in agony'') It hurts... it hurts...! (...) It's ''you'' that's causing my suffering. Then, if I tear you to pieces... the pain will stop...!

** ThatOneBoss or no, Flame Hyenard's situation is both horrifying and [[TearJerker saddening]] to think about. He's constantly in pain due to the Sigma Virus, and has been suffering since before you got to him. If his in-game dialogue is anything to go by, as well as the only reason he attacks X, Zero, or Axl being that he thinks it'll get rid of his pain, this torment has been driving him to complete insanity. When you finally do fight him, the infection's in such a late stage that the only way to cure him is to put him out of his misery.
** A cartoonish video game soundtrack seems like an odd place for nightmare fuel, no? The "[[https://www.youtube.com/watch?v=UXUmCW0zMBo Soul Asylum]]" track disagrees with you. The distorted effects in the track are almost hypnotic...

** Sigma's ominous Final Stage on ''Mega Man X''. It consists of a single narrow pit you must wall climb to reach Sigma, devoid of enemies apart from two holes in the walls of it that spawn tiny maggot-like robots. The eerily calm stage, with [[https://www.youtube.com/watch?v=bziJONWj8XM disturbing minimalist music]] as the background plays NothingIsScarier all too well.
** The {{Stinger}} at the end of the credits can be rather unsettling the first time you see it. Sigma taunts X from beyond the grave, threatening to gather new Mavericks to continue his war. The same disturbing minimalist music that plays during the final stage also plays during this scene. It doesn't help that like most early ''Mega Man'' games, you can't exit to the title screen, leaving you hearing the music and staring at Sigma's visage until you turn the game off yourself.
-->'''Sigma:''' You have won a temporary victory, X. What you destroyed was only a temporary body -- my spirit remains intact. In time, [[DemonicPossession I will find other bodies strong enough to do my bidding]], [[WeWillMeetAgain and I will return]]. I shall see you soon, X. '''Very soon...'''
