Time Eater (Archie)

The Time Eater is a character in the Sonic the Hedgehog comic series and its spin-offs. It is the remains and an alternate state of Mephiles that managed to slip through the cranks of time before his complete destruction.

Creation
Following Mephiles' destruction that led to him being erased from the timeline, the remains of him managed to slip through the cranks in time. These remains then gained a new form and independence, becoming the Time Eater.

Worlds Collide
The Time Eater was brought into the reality of Mobius Prime after the Prime Zone had its timeline altered by Dr. Eggman and Dr. Wily's Genesis Wave. However, the Time Eater was stopped by Sonic at some point in this new reality's past. Dr. Light later brought up the Time Eater to Eggman in an attempt to state Eggman's experiences about tampering with forces that he could not control.

Trivia

 * According to Ian Flynn on the Bumbleking forums, he believes that SEGA implied that the Time Eater was the leftover matter of Mephiles, as such he stated that the Time Eater is an alternate state of Mephiles in the Archie comic that "slipped through a crack in time".
