Error

"Error" is an antagonist in the Glitch Chaos series. Not much information has been revealed about him at the moment, and his actual name is unknown.

Past
After Exester was taken away from their family and turned into an Exe, they were sent to Error for experiments and testing, turning them into some sort of code-virus.

Sonic.exe The Glitch Chaos
Error is first seen in Version 2 when Sonic reaches the end of Green Hill, where he is found by Sonic, and proceeds to insert Exester's soul into Sonic, killing the latter in the process. It cuts to static, and it shows dialogue presumably made by Error.

After Tails enters the Warp Ring, Exester is seen in a black abyss with illusions of themself popping around around them, with Error watching. Exester seems to crack under the pressure, but it flashes white and they run away, starting a level where Exester is trying to escape both the illusions and Error.

Sonic.exe The Glitch Chaos {CODE_CORRUPTION_}
Error does not actually appear in the game as of its current progress, but he is mentioned by Exester and Nameless. When the two are in Sakura Town, Exester worries about Error hurting those they turned into Exes or making them suffer to make them say where Exester is.

Personality
Error is malevolent, appearing to see the events happening in the timelines as just "fun". He torments Exester and controls them to make them kill others for an unknown reason, and feels no guilt for it.

Appearance
Error looks like Super Sonic, but with purple fur, light purple skin, and glowing eyes that are completely white with black dripping out of them. He has a fuzzy chest, and his shoes are white on the tips with the soles being white. The inside of his mouth is black.

Old design
Error looks like Super Sonic, but with more purplish blue fur and glowing eyes that are completely white.

Abilities
Error can create illusions, fly, and take control of Exester to cause harm.
