Mephiles The Dark

Origin
Mephiles the Dark is one of the main villains of the game Sonic the Hedgehog (2006). He is the conscious mind and will of the Sun god Solaris. Mephiles is the final boss of Shadow the Hedgehog's story, although he plays a pivotal role in all three of the game's storylines. He is a skilled manipulator, tricking Silver into believing that Sonic was the Iblis Trigger and thus that killing Sonic would save Silver's future. He also has a particular interest in Shadow, who originally imprisoned him after his creation, and whose appearance and powers Mephiles absorbed upon his release. Mephiles repeatedly attempted to convince Shadow to join him, but Shadow refused each time. He is notable as the villain that killed Sonic the Hedgehog, although Sonic was later resurrected.
