Mephiles the Dark

Mephiles the Dark (闇のメフィレス) is one of two primary antagonists in Sonic the Hedgehog (2006). He is the conscience, mind and will of the sun god Solaris. Mephiles was born during the Solaris Project when the experimentations on Solaris caused him to split into Mephiles and Iblis. Shortly after his birth, Mephiles was sealed inside the Scepter of Darkness by Shadow the Hedgehog, who had traveled back in time to learn about the Solaris Project. Ten years later, Mephiles was freed during a skirmish between Shadow, Rouge and Dr. Eggman where he was resurrected through Shadow's shade.

After his release, Mephiles orchestrated a plan that spanned over two hundred years to release Iblis from Princess Elise to rejoin with it. Along the way, Mephiles attempted fruitlessly to convince Shadow to join him, having taken a particular interest him. By manipulating several individuals across time, Mephiles was ultimately successful in his plan when he personally killed Sonic the Hedgehog. Mephiles then reemerged with Iblis, remaking Solaris, and prepared to bring the end of time, but was defeated by Sonic, Shadow and Silver. Mephiles was then completely erased from the timeline when Elise and Sonic traveled back in time to before the Solaris Project and brought an end to Solaris.
