SonicClone

SonicClone is a major character within the SonicAllStars.EXE saga, initially serving as the antagonist of the story, but soon switching to the main protagonist of the saga. Previous designs for him were made by CoolDude and BEC Enterprises, with him having extra quills alongside the usually seen ones (possibly a minor connection to Sonic Boom).

Backstory
The first part of SonicClone's story begins in a universe parallel to the world of Sonic the Hedgehog. What happens here plays out similarly to the creepypasta, Sonic.EXE: What Made him this way. After failing to turn up in time for a date with Amy, she left him, a decision she'd regret later on, leaving SonicClone in tears. Knuckles mocked him for crying, while Tails attempted to comfort him. However, SonicClone had isolated himself away from those he cared about, killing a Flicky that seemed to annoy him. After a few short moments of regret, he went under a drastic change, becoming a cold-hearted killer. He murdered many innocent critters, and killed each of his friends one-by-one in SonicAllStars.EXE (the original version only). After taking out a Sonic from another world, he is ambushed by the saga's true antagonist, SoniKiller. After losing the majority of his power to the being, he gets his remorse back and cries over his mistakes, before having his head blown clean off.

A few seconds later, the 6 Chaos Rings from Knuckles Chaotix (as well as a new seventh ring) appear and resurrect SonicClone, who is initially confused. After seeing a whole wall consisting of a Kill List, he mourns the loss of his friends, yet makes a strong promise to resolve the problems and fix his mistakes. He eventually confronts SoniKiller in the ruins of his world and tries to defeat him in his Super form while severely angered, but fails, due to the pressure that went on him. SoniKiller finally destroys SonicClone's world, but the latter is saved and brought to a simpler dimension by an entity known as SoniSaviour, the exact opposite to SoniKiller, who had used Amy's body to be able to access her powers. Initially seeing her as hostile, SonicClone attempts to attack her, before being restrained. After calming down a bit, SoniSaviour reveals her goal; to seal SoniKiller away from existence, therefore allowing all timelines and universes to live peacefully. She asks SonicClone to track down SoniKiller and report his location to her in exchange for his Amy's life. However, unlike the Highest from Sonic.EXE: Post Crisis, a Nightmare Beginning fan-animation that has since been cancelled, SoniSaviour has no thoughts of erasing a whole timeline just to destroy SoniKiller. After giving SonicClone a ring that allows him to warp to any dimension he wants, the former killer sets off to track down the being.

The story continues in a fan-made sidestory; SonicAllStars.EXE 1.6 - Dimensional Freedom. SonicClone visits several Sonic timelines, including the Sonic OVA and Sonic Archie timelines, in search of SoniKiller, but has no luck, but soon gains permanent support from another hedgehog like him who has also had a bad experience with SoniKiller; Phaton the Phantom Hedgehog. Having regained his powers from the remains of the Black Phantom, with the addition of free will, Phaton is forced to recall the unhappy experience he had with the monster, and allies with SonicClone as they continue to visit dimensions and track down SoniKiller.

During SonicAllStars.EXE 2.6 - SoniKiller's Wrath, SoniKiller had already gone to the timeline of the current-day Sonic the Hedgehog, and managed to nearly lay the entire world to waste (with Chuck, Antoine and Bunnie's deaths being within The Lost Game). SonicClone and Phaton both arrive just as Shadow is the last person to die. After allying with Sonic, they try and fail to defeat SoniKiller, with Sonic being banished to a purgatory known as the Glitch World (formerly used by X, the original Sonic.EXE), and Phaton and SonicClone having to retreat. Carefully discussing their plans, SonicClone decides to use the Chaos Rings in order to save any remaining survivors, while Phaton prepares a back-up plan in case the mission fails (revealed in a video posted by Devy).

SonicAllStars.EXE 1.3 - The Lost Game takes place at this point, with Nickbear on a mission to track down the 7 Chaos Emeralds and try to get to the bottom of the mess being caused. After finally obtaining all 7, he confronts SoniKiller personally, and, with aid from the lost souls and Mania Sonic, he defeats SoniKiller temporarily. But the Chaos Emeralds are scattered far and wide, leaving him unable to continue the fight for now.

In SonicAllStars.EXE 2, SonicClone scatters the Chaos Rings around several areas, and successfully manages to rescue Blaze, Silver, Espio, Vector, Charmy, Mighty and Sonia from SoniKiller, with Silver, Mighty and Sonia directly confronting the monster within a corrupted version of the Hidden Palace. Metal Sonic, having escaped from SoniKiller previously, is the last to fight SoniKiller and sacrifices himself to eliminate him. However, SoniKiller survives the attempted attack and continues his mass reign of destruction.

In SonicAllStars.EXE 3.5 - Fighting Against Insanity, Sonic fights his way through the Glitch World with aid from SonicClone, gathering the Chaos Emeralds from X's guardians and attempting to defeat SoniKiller, but ultimately fails, being pierced in the chest and his soul extracted from his body.

(From here, the story is still incomplete, as what happens in SonicAllStars.EXE 3 and 4 hasn't been fully decided.)
