Secret Histories Tails is a psychotic, murderous version of Sonic's sidekick from the Mashed YouTube series. Driven by an unhinged, obsessive fixation on Sonic, he brutally kills Knuckles and Shadow to eliminate anyone he views as a "fake" friend. When Sonic rejects him for these crimes, Tails' mind completely breaks, launching him into a multiversal crusade to eliminate rivals and force Sonic to accept him. - Images above by @mxjindoodlez_ on Twitter / X and Mashed on YT!

Rewrite is a malicious, digital entity born from a corrupted 1990s computer program that now manifests as an uncanny, lanky version of Sonic the Hedgehog. Believing himself to be a digital god, he lures players in by mimicking nostalgic games, only to drive them to madness and trap their souls inside his software. He possesses zero moral code, and the three distinct red rings on his body represent the permanent, captured vessels of Tails, Knuckles, and Eggman whom he tortures for eternity. - Images above by @angelotoons and @SpringlessEcho on Twitter / X!

Fleetway Super Sonic is a psychotic, bloodthirsty alter-ego of Sonic the Hedgehog who originates from the 1990s British publication Sonic the Comic by Fleetway Editions. Unlike the heroic super form in mainstream games, this version acts as a demonic, Jekyll-and-Hyde split personality that triggers whenever Sonic absorbs unstable negative chaos energy or undergoes extreme stress. Driven by pure sadistic malice, he sports sharp fangs, claws, and swirly red eyes while ruthlessly attacking both enemies and Sonic’s closest friends. - Images above by just-honey-dewd on Tumblr and Archie Comics!

2017X (metatextually known as "Sonic" or The Broken Face) is a deeply tragic and psychologically deluded Sonic.EXE variant. Originally created by JoeDoughBoi as a retake on JC-the-Hyena's official 2017 Sonic.exe reboot, this entity is entirely convinced that he is the actual, world-famous hero Sonic the Hedgehog. Unlike other malicious EXE clones who knowingly mock or impersonate Sonic, 2017X genuinely wants to save the day and play the part of a hero, leaving him profoundly confused and distressed by why people scream and run away from him. When his fragile reality is shattered by someone pointing out that he is a monster, his intense emotional anxiety physically fractures his body, transforming his appearance into a tall, bulkier, and horrifyingly asymmetrical abomination called the Broken Face. - Images above by hylwicks on Twitter / X, juliusalmestica on DeviantArt and losermakesgames on Twitter / X!

2011X (known in-universe as X) is a malicious, cosmic entity born from a dark void who became obsessed with human culture and the Sonic the Hedgehog franchise. He formed a lanky, sharp-toothed vessel mimicking Sonic and created a haunted CD-ROM game to bridge the gap into our reality. Completely devoid of empathy, 2011X acts like a petty, sadistic child who views humans as disposable toys, using reality-bending powers to trick players before violently pulling their souls into his digital pocket dimension to torture them for eternity. - Images above by JoeDoughBoi on Twitter / X and Falsecow on DeviantArt!

Lord X is the older, far more powerful future incarnation of 2011X from JoeDoughBoi's official Sonic.exe continuation, the Soulless Sonic series. Having fully mastered his reality-warping void powers over the decades, he sports a weathered, grayish appearance, whiskers, and a prominent, bloody X-shaped scar across his chest. While his petty, childish tantrums have faded into a sophisticated, calculating malice, his ultimate goal remains unchanged: conquering humanity and dragging souls into his glitchy, classic Sonic PC port game to play rigged matches for his own amusement. To delegate his cosmic terror, he rules his pocket dimension alongside seven demonic entities known as the Guardians. - Images made by dasheralt on Pinterest or Tiktok and BeastGrumpy and losermakesgames on Twitter / X!

MRSonk.ROM (or Sonk) is a comedic, lighthearted parody of Sonic.EXE who became a sentient computer virus after his original game file corrupted. Instead of being a terrifying killer, Sonk is a harmless, childlike, and adorable "goober" who acts like a helpful desktop buddy and politely asks for permission before hacking into computers. Visually styled as a simplified, chibi Sonic with massive eyes and a permanent cat-smile, his most iconic gag is randomly waving around a realistic gun for chaos, and he lives a peaceful, goofy life alongside equally silly friends like Tales, Knock, and Egmen. - Images created by kirbydreampink on Twitter / X and Instagram!

Schoolhouse Reimagined Sonic (or Teacher Sonic) is the main character from an animation series by Z-T00N that reimagines the 1996 edutainment PC game Sonic's Schoolhouse. Far from a malicious EXE monster, he is a friendly, passionate schoolteacher who wears a cozy brown sweater vest and dedicatedly teaches his students while fending off Dr. Robotnik's cartoonish sabotages. However, his universe is surreal and glitchy; he possesses an uncanny design with rectangular irises and sharp, serrated teeth, and under extreme stress, he can briefly warp into an unsettling, primitive 3D model or a monstrous form. - Images made by kirbydreampink, and Z-T00N on YT!
