-> ''The [[RuleOfCool craziest journey]] you will ever take with your [[Franchise/SonicTheHedgehog favorite blue hedgehog!]]''

''Sonic [=ERaZor=]'' is a [[GameMod ROM hack]] of ''VideoGame/SonicTheHedgehog1'' created by Selbi. It became known throughout the Sonic ROM hacking community for its unique and [[PlatformHell rage-inducing]] gimmicks, as well as its hardness in general.

There have been six releases in total; you can get them all [[http://info.sonicretro.org/Sonic_ERaZor here.]] A sequel has been [[https://www.youtube.com/watch?v=9ht0-e7rxss hinted at.]]

Not to be confused with the antagonist of ''VideoGame/SonicAndTheSecretRings'', or with ''VideoGame/SonicEraser''.
----
!!This video game provides examples of:
* ActionBomb: The grey Bomb in Scar Night Place explodes countless times before dying for good.
* AlwaysNight: Night Hill Place.
* AntiFrustrationFeatures: The Hard Part Skipper will [[ExactlyWhatItSaysOnTheTin skip particularly challenging parts of a level]], though any rings or powerups are lost in the process.
* ArtEvolution: The spikes in the Ruined Place went from simple red dots on the tip to more obviously bloody.
* BloodierAndGorier: There are a few bloody spikes here and there.
* BroughtDownToBadass: Midway through the Ruined Place, one finds an S Monitor that grants a different Inhuman Mode that strips Sonic of all his abilities (except for invincibility and the bullet shooting) and saps his rings at a ''very'' quick rate while still and a less fast rate while moving, ''and'' you die when it hits zero. While in this state, you must navigate through a maze of bloody spikes that teleport Sonic back to the start if he touches them (thus making your invincibility worthless).
* BrutalBonusLevel: [[spoiler:The Black Challenge in the Fulfilled Edition. It's a much harder version of Unreal Place where [[InterfaceScrew almost everything is pitch-black]] and you're rotating the maze instead of moving Sonic.]]
* DoubleJump
* DownerEnding: In the game's pre-credit sequence where Sonic runs through Green Hill Zone, [[spoiler:he fails to stop in time and goes into a [[BottomlessPit pit]], instantly killing him. Directly after, a text saying [[TrollingCreator "U Mad Bro?"]] appears on screen, followed by the credits.]]
* DungeonBypass: One Website/YouTube user found another way to get to the EasterEgg mentioned below.
* EasterEgg: Through some fancy tricks in the Star Agony Place, you can get to a secret screen with a [[VulgarHumor little story]] on it...
* ExactlyWhatItSaysOnTheTin: The Hard Part Skipper.
* ForcedTutorial: Completely averted - there is a warp ring to the left of your starting point in the Tutorial Place that skips the whole thing.
* GravityMaster: Sonic gains this ability in the Star Agony Place.
* HubLevel: Uberhub Place.
* InvincibleMinorMinion: There are invincible Buzz Bombers behind a waterfall in one section of Night Hill Place.
* LemonyNarrator: From Special Place onwards. Unreal Place and Scar Night Place don't continue the story at all, instead talking to the player about the gameplay that just occurred.
* MiniBoss: A Bomb serves as one in Scar Night Place.
* NintendoHard: And that's if you're ''good.''
* NostalgiaLevel: Green Hill Place is mostly unchanged, save for the enemies ''constantly exploding.''
* RatchetScrolling: A vertical variation is used in Labyrinth Place. {{Justified|Trope}}, as due to the ring-draining TimedMission in the previous stage, Sonic is not able to pay his camera crew.
* ShootTheShaggyDog: [[spoiler:Sonic runs off a cliff and dies in the ending. This is followed by [[LampshadeHanging "U MAD BRO?!"]] appearing.]]
* ShoutOut: All the music is taken from other games.
* ShowsDamage: The Green Hill Place boss loses his spiked balls as he takes damage, and when he's down to the last ball the three floating platforms disappear as well.
* StuffBlowingUp: '''''Everywhere.''''' In fact, the end of the tutorial lampshades it:
--> "They call me the Creator/MichaelBay of Sonic games."
* StupidityIsTheOnlyOption: In the Ruined Place, a spike blocks your progress unless you grab a S Monitor that sets off a deadly TimedMission.
* SuperMode: Super Sonic is absent, but breaking an S Monitor grants Sonic "Inhuman Mode", where he is ''completely'' invincible and can fire bullets (that can also be used to propel oneself into the air).
* SuspiciousVideoGameGenerosity: A shutter rains rings on you just before the final boss.
* TakeThatAudience: Beat the first Special Place and the game outright ''insults you''.
--> "If I see such a pathetic excuse of what you call skill again, I will go ahead and disable the checkpoints until you can do this stage while you are asleep!"
** Beating Labyrinth Place also describes your performance as pathetic.
* TimedMission: The aforementioned Ruined Place maze.
--> ''Think of the movie ''Film/{{Speed}}'', but with a hedgehog.''
* TrappedInAnotherWorld: The plot involves Sonic escaping a giant Buzz Bomber, then accidentally falling into a giant ring that transports him into a strange parallel dimension.
* TrialAndErrorGameplay: The tutorial outright admits so.
* VulgarHumor: The EasterEgg in the Star Agony Place level, which consists of a screen describing people sticking their dicks in other people. Lampshaded by the end-of-level screen, which mentions "an incredibly inappropriate[[RougeAnglesOfSatin d]] easter egg".
