Deadly Six

The Deadly Six (六­鬼衆) is a villainous group of six Zetis  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.

Trivia

 * Each member of the Deadly Six shares certain characteristics:
 * Each member has at least one horn on their head.
 * Each member has black legs and hips.
 * Each member's name starts with "Z".
 * All members have stripes on their horns.
 * The colors of these villains match those of six of the Chaos Emeralds (red, yellow, green, purple, cyan and grey more precisely). They also resemble the colors of various Wisps (Green Wisp, Pink Wisp, Purple Wisp, Blue Wisp, Yellow Wisp, Cyan Wisp and Red Wisp).
 * Similar to other powerful entities, Dr. Eggman attempts to control the Deadly Six in order to take the world over, only for the entities to turn against him. The main difference is that it happens early on in the game, rather than towards the end.
