Following his apparent disappearance in the events of Sonic 2006, Mephiles survived in the shadow of time, but without Iblis, his other half. In his quest for power, he found the scattered fragments of the core of the Time Eater, an entity with absolute dominion over time and space. Patiently, he gathered them and rebuilt the core, absorbing their energy and being reborn as Mephiles, Time God. Now, his existence not only transcends reality, but consumes it. Also called Timephiles
*you can see Mephiles fight Shadow, in one of those Mephiles stops and explains his return*
"Hehehe. It will be the next problem that I will solve. But for now, what you can understand... When I finally reached my goal, and I managed to merge with my brother Iblis. I have achieved the supreme power to destroy all timelines. But what I didn't count on, was the power of your teamwork. I was defeated... And erased from history... But I managed to survive thanks to my temporal control skills, unfortunately my brother Iblis was not so lucky. And you, Shadow, will be the first to receive my revenge"
*when I see Shadow take out a Chaos Emerald, Mephiles smiles as he takes out the Time Eater core*
"In this case... I better give an equivalent answer. He He... I managed to pique your curiosity, Shadow. This is my guarantee of victory. The core of Time Eater. oh, you're wrong. I spent a lot of time hiding, waiting for an opportunity. And she finally appeared... After Sonics broke the core of Time Eater. I spent a lot of time collecting its fragments, and recreating a part of its core. The core of a god"
*Mephiles absorbs the core of the Time Eater, transforming me into Timephiles, although Shadow tries to use Chaos Control to stop time on him, Timephiles is immune and begins to attack*
"The power to change the timeline. You can call me Mephiles Time God"
*Timephiles fights Shadow showing his superiority even though Shadow removes his inhibitor rings, after which Timephiles manages to eradicate Shadow. Timephiles removes the Time Eater core from his body, returning to his base state as classic Mephiles for now, and smiles*
"Finally he's gone... But the emerald disappeared... But it doesn't matter, now there are only 2 more... And then, the destruction of the entire timeline..."
