Time Eater (Sonic Speed)

Time Eater is a major antagonist in ''Sonic Speed. ''Initially an alien creature with dominion over time and space, the Time Eater was discovered by Dr. Eggman who used it in an attempt to conquer the world by erasing his past failures.

Past
The Time Eater was originally a supernatural being of unknown origin whose primordial form drifted through the space of Sonic's universe. Eventually, it was discovered by Dr. Eggman, Orbot and Cubot shortly after the destruction of the doctor's interstellar amusement park. Discovering the Time Eater's abilities, Eggman had the idea of using it to undo his numerous defeats at the hands of Sonic by erasing the blue hero's history, thus changing his failed attempts for world conquest to successes. Taking the Time Eater with him, Eggman converted it into a cyborg-like machine that allows him to control it and even so, the mad scientist began using the Time Eater to interfere with history.

Season Eleven
The Time Eater crashed a birthday party for Sonic where Eggman had it create time holes that scattered Sonic's friends throughout time to bait him into his traps. In the process, the Time Eater knocked out Sonic when he tried to stop it and took him to the White Space too. The Time Eater reappeared after Sonic's victory over the Death Egg Robot on the Death Egg where it "kidnapped" Eggman. As the Time Eater went on more time travels, it passed through the White Space several times during which it collided with a Chaos Emerald. When Sonic defeated the Egg Dragoon, Time Eater appeared briefly and took Eggman again with it.

After the Time Eater had been perfected, Sonic arrived in it's dimension to finally stop it. It was then Eggman revealed himself as the one controlling the Time Eater and explained everything to the hero, the doctor then unveiled his endgame: to destroy Sonic with the Time Eater, thus erasing him from the timeline entirely. Sonic tried to engage the Time Eater, but Eggman ambushed him by launching the Time Eater's arm through a time hole, squashing the hedgehog. As the Time Eater prepared to finish him off, however, Sonic's friends arrived and cheered him on, causing the Chaos Emeralds to emerge and Sonic transforms into Super Sonic. Sonic then faced the Time Eater in another dimension and destroyed it, leaving Eggman stranded in the White Space and undoing all the Time Eater's actions.

Personality
Time Eater is more of a force than a living creature and unlike most other supernatural beings, it is devoid of sentience, independent thought and rebellious tendencies as it never once tried to betray Eggman. However, it displays some traits of a living being, such as making growls and displaying dislikes of unfavorable objects.
