Mephiles Worms are supernatural beasts, controlled by Mephiles, that serve as his minions in Sonic the Hedgehog (2006).

Description
The Mephiles Worm is an enormous purple creature that resembles a parasite. It is the Mephiles counterpart of the Iblis Worm, one of Iblis' minions, and shares a very similar appearance. However, it is stronger than the Iblis Worm, possessing twice as much health, and requiring twice as many hits to be defeated. In addition to the usual attack patterns of Iblis Worms, Mephiles Worms have the added ability of breathing poisonous gas on the player.

Trivia

 * They resemble the worms of the Black Arms in Shadow the Hedgehog.
