Deadly Six

The Deadly Six is a villainous group of six unspecified, menacing creatures that is set to appear in the upcoming game Sonic Lost World.

In Sonic Lost World, Dr. Eggman harnesses the power of the Deadly Six in an attempt to defeat Sonic the Hedgehog and conquer the world. However, the Deadly Six rise up against Eggman and break free, threatening to destroy the world on their own.

Concept and Creation
According to Takashi Iizuka, the Deadly Six are meant to bring a “sense of danger and humor” to the story of Sonic Lost World.
