— His promise to a wounded and dying Redstone, Redstone's Nightmare
Sonic.EXE is a character appearing in The Legend of Fox the Brave. He is a demonic hedgehog that resembles Sonic yet is as old as the Four Worlds. He is an ancient demon with unknown origins that was defeated by Redstone the Fox in ancient times and has had a bloody vendetta against him since. As of Darkness of War, he is no more and will make no further appearances in modern stories.
It has been noted several times that he resembles Sonic the Hedgehog, but with several key differences. First, his fur color is much darker, and notably stained with blood. His eyes are pure red with black sclera and bloodstains below them, he has sharp, claw-like fingers, and viciously sharp, bloodstained teeth. He often has a sadistic, sneering grin on his face, but while he is sometimes seen with a different expression, this is rare.
Confident in his abilities and strength, Sonic.EXE is extremely arrogant. Additionally, he is horrifically cruel, sadistic, and ruthless. When targeting someone, he likes to "play" with them, usually through nightmares, taunts, and threats aimed at the target's loved ones. If he loses, he becomes extremely serious
Sonic.EXE's past in the series is largely unknown other than his defeat at the hands of Redstone the Fox and subsequent desire to completely destroy Redstone's bloodline.
In Ancient Times: Sonic.EXE's origins are unknown. When the Worlds were new, a fox named Redstone started suffering from regular nightmares from an unknown entity shaped like a hedgehog. Not long afterward, a string of mysterious and gruesome murders happened, prompting Redstone to look into them with his friends Vero the Greninja and Jagged Cliff the Cat. When Jagged Cliff became one of the victims, found by Redstone, Vero, and Garrett just before he died, Redstone swore vengeance and fought Sonic.EXE for the first time. Redstone was left badly wounded in the fight, and the wound refused to heal. In their second battle, Redstone won with help from a water kunai tossed to him by Vero, with which he caught Sonic.EXE in the midsection with. Knowing he was defeated, Sonic.EXE began to fade away with a last warning to Redstone: That he would haunt his kin until they were all eradicated once and for all, as revenge for his defeat
Modern Times: In The Lost Story of Rocket the Fox, Sonic.EXE murdered two red foxes, Andrew and Dalhia, and stalked their son Rocket, who he had wounded. Rocket was killed in a later attack. In The Legend Begins, he tricks Eggman into going after Rocket's son Torch and his own family. Eggman tries to get Torch to rejoin him, but when Torch refuses, the fox is killed alongside his wife. Torch's son Red flees, but his daughter Sadie's fate is unknown. Sonic.EXE later torments Red in his dreams, tearing his ear and ripping open his belly. He isn't seen after the second nightmare until Red changes his name to Fox the Brave and returns to Soleanna Forest. There, he murders Grizzly, prompting the fox's son Maako and daughter Karra to go with Fox. He later attacks Fox at the Base during a rainstorm, but while he is unable to harm Fox, he kills Kairn the Coyote and Maako, and badly wounds Longmire the Cat. He goes dormant for many years, until after the Battle for Red Gate City, when he attacks a warrior patrol. He wounds Austin, Ash, Eli, and Cody. He later attacks Sleet the Fox and Manuel "Manny" Sanchez(a human) in an abandoned house in New Ninjago City, killing Manny and nearly killing Sleet. He is later defeated for the last time by Fox as Chaos Fox.
Sonic.EXE's most defining feats are that he is immortal, can float, teleport, and enter dreams.
Sonic.EXE is incredibly strong and durable, capable of lifting people up by the throat easily and can take several powerful hits with ease.
While Sonic.EXE is immortal, he is not invincible-although he believes he is. He is weak to fire-based attacks, and presumably any light-based attacks as a result.
He is one of several main villains to not be a character original to the series, the others being Mephiles the Dark, Dr. Finitevus, Dr. Eggman, Enerjak(Prime and Dark), Infinite(Jackal Squad and Current Identity), and Dr. Starline.

Sonic.EXE is arguably the darkest and most violent villain of the series, with each of his kills being quite bloody.
