Mephiles the Dark is a recurring character in the animated series, Sonic Adventures. He is the evil anthropomorphic black hedgehog/black arm hybrid created by Black Doom, and is the sworn enemy of Shadow and all his friends and rivals.


Due to the series being a modern culture reboot of the original video game series, each character had to had a design that either matches their identity or references. Mephiles has on a black Gothic clothes and also has on his regular shoes and gloves.


Unlike most of the villains in the Sonic series, who are driven by a lust for power or revenge, Mephiles (according to Shadow) only seems to crave nothing more or less than violence and destruction. He is portrayed as a murderous, heartless, malevolent, vicious, and ruthless sadist with no sense of compassion or empathy, and would do anything to accomplish his goals, even if it means taking innocent lives. Mephiles happens to take great sadistic pleasure and delight in hurting others and has been shown to have a very warped and twisted sense of humor, making him a very cruel and unsympathetic being. 

Despite his villainous tendacies, he has demonstrated some fortitude, such as when he willingly let Shadow beat him into submission and even laughed vengefully when the latter intensified in his attack.

  • During the planning and production of the series, it was initially stated that Mephiles was not going to be part of Sonic Adventures. The reason for this is if he was to be in the show, it had to be that he didn't have any silly or goofy animations. It was also stated that Sonic Next Gen wasn't going to be part of the Sonic Adventures timeline, due to so much hate from the fans for all of the glitches in the game. During production of Sharing's Caring, the creator came up with the Episode "The Creation of Mephiles" which both serves the Characters and borrows some of Sonic and Shadow's story-lines from Sonic Next Gen.
  • Mephiles' Outit is Influenced By the American Fantasy-Drama television series, "Game Of Thrones".
  • In Most Episodes, Mephiles parodies characters such as ManRay and Sheldon Plankton from SpongeBob SquarePants and Slade and Trigon from Teen Titans and Teen Titans Go!.
