** [[http://sonicintent.blogspot.com/2009/06/sonicnot-so-universe-rant-warning-ahead.html The .gif at the end of this blog post]] makes this [[BodyHorror all too clear]]. [[spoiler:It's a picture of Sonic, with the "bridge" between his eyes ''lifting up'' and his pupils '''''becoming one.''''']]

* In ''VideoGame/SonicAndTheSecretRings'' at the very end of the game Erazor Djinn absorbs the 7 seven world rings despite haveing botched the ritual needed to control them by killing Shahra instead of Sonic. He nearly undergoes a SuperpowerMeltdown then and there, as we're treated to several shots of his [[BodyHorror body painfully warping]], briefly becoming an indecipherable mass of limbs before he finally transforms into Alf Layla wa-Layla; a six armed top heavy monster with three hollow holes for eyes. And throughout all of this he's ranting about his intentions to completely rewrite all of reality, not even caring about what he's become. The normally cool and collected Sonic is completely horrified at witnessing all this.

* Likewise, Sonic's DeathThrows sprites can also catch the player by surprise, especially after traveling at fast speeds. Or if you get crushed to death. Or if you [[TimedMission lose track of the stage timer]] and suddenly die to a Time Over.

* Any time you take a hit and you lose your rings. '''BRRRRIIINNNGGG!''' Quite the jumpscare.
* Sonic's DeathThrows sprites can easily catch the player by surprise, especially if it happens while traveling at high speeds — the sudden stop is almost like a JumpScare of sorts.
* Death by getting crushed is one of the most common and feared ways of dying after drowning, due to the fact that ''nothing'' protects against it. You can be Super Sonic with 300 Rings remaining and still be paranoid around platforming sections because something could unexpectedly come down upon you or a moving platform you're on could push you up into the ceiling or a bed of upside-down spikes. It doesn't help that in some of the games, the hit detection for death by crushing can be [[HitboxDissonance wonky]], causing you to be [[JumpScare abruptly]] killed because you passed through a crush trap moving ''away'' from whatever surface it's designed to smash you against.

* Doctor Eggman's classic western design. Once an [[https://web.archive.org/web/20181108040326if_/http://eggmanempire.sonicworld.net/downloads/images/official/classic/poses2.gif adorable]] [[https://web.archive.org/web/20071212045720if_/http://eggmanempire.sonicworld.net/downloads/images/official/classic/poses.gif spherical humanoid]] with traits of [[Music/TheBeatles both eggs and walruses]], his cutesy appearance was changed [[AmericanKirbyIsHardcore when he hit American and European shores]], and he was molded into this [[https://web.archive.org/web/20181108040533if_/http://eggmanempire.sonicworld.net/downloads/images/official/soa/chaosartwork.png much more]] [[https://web.archive.org/web/20071212045438if_/http://eggmanempire.sonicworld.net/downloads/images/official/soa/Spinball_eggman.png menacing creature.]]

* We get a little more insight into just how powerful the Chaos Emeralds are in this game. During the pre-final boss cutscene, the two Eggmen spell out the Chaos Emeralds and Sol Emeralds act as two sets, and when they come into close proximity with each other, they generate enough power to alter the fabric of reality, and even allow parallel worlds to cross over and overlap with each other. [[ParanoiaFuel Now imagine what somebody like Eggman Nega would do if he had full control over that kind of power.]]

* If you don't collect all of the Chaos Emeralds, you get Eggman Nega telling you to collect them, accompanied by a creepy tune.

* One of the most creepy moments was the [[NothingIsScarier open interpretation]] of the [[MultipleEndings incomplete ending]] of the Game Gear version of ''Sonic 2'', in which Tails gets kidnapped by Dr. Robotnik. If you don't collect all the [[PlotCoupon Chaos Emeralds]] throughout the game, then you do not gain access to Crystal Egg Zone and have the [[DownerEnding bad ending]] [[https://www.youtube.com/watch?v=IZ19n421nBc credits]], at the end of which Sonic looks up and sees [[spoiler:a constellation of Tails in the sky]], which could very well pertain to [[spoiler:Tails' presumed death]]. [=YouTube=] user LetsPlay/WhoIsThisGit [[https://www.youtube.com/watch?v=HCQZOh2faww had a field day with that one.]]

* The bad ending of ''VideoGame/KnucklesChaotix'' shows [[https://www.youtube.com/watch?v=ar8NEvPKVLM&t=6m57s the final boss hovering over a city in flames,]] the implication being it just burned the whole place down.

* ''VideoGame/SonicR'' has the Tails Doll, a blood-red gem dangling over the head of a doll sewed in the glory of the cute mutant fox. While it's one of the most harmless characters, the floating gem makes the doll's movements jerky and out of place compared to the others, making it [[CreepyDoll creepier than it intended to be]].

* The Tails Doll. Even though fans "made him creepy," a CreepyDoll based off Tails that has a blood-red gem dangling over his head is rather creepy enough already.

** The boss theme makes it even more off-putting by focusing on tension with low-key pianos with its similarities to the US Sonic CD boss theme in that regard.

* The boss of Lava Powerhouse, Roboboiler, is this because of its appearance: [[https://www.youtube.com/watch?v=Paq4kdpZumY&#t=2m00s Four disembodied Robotnik heads that vomit magma every time they're hit]]. Not just that, if Sonic falls down the drain during that boss battle, he will fall down to an area where the lava cauldron is, and only managed to barely avoid being dunked by hanging onto a chain. The game gives you no instruction on how to escape the trap, so if you haven't encountered it before or read a guide before-hand, you're forced to figure out the right button combination in a high-stress situation, hoping you don't make the wrong move, all before the 5 second countdown expires. This is notably the ''only'' boss out of the four where draining out of the boss arena puts you in a life-or-death situation rather than just safely sending you back into the main portion of the stage.
