Egg Boss

Sub-Bosses, or Underbosses (many of whom were renamed Grandmasters following the formation of the Dark Egg Legion), were beings originally employed by Dr. Ivo Robotnik to watch over various territories across Mobius he controlled to enforce his will, and to annihilate opposing forces who threatened his empire. After his death Dr. Eggman employed old and new Sub-Bosses to serve his own dictatorship.

History
Formerly, Sub-Bosses were known to have been located in Angel Island twice, Sand Blast City, the Dragon Kingdom twice, the Great Canyon and the Kingdom of Mercia. All of these Sub-Bosses were subsequently defeated or destroyed by the local resistance, sometimes with help from the Knothole Freedom Fighters. (StH: #58, #138, #181, KtE: #12, TMS: #1, #3, STT)

As of 3237, the Eggman Empire had various Sub-Bosses stationed at Flicky Isle, Station Square, the Land of a Million Lights, Southern Tundra, Downunda twice, and the Mobian Sea twice. However, due to the decline of Dr. Eggman's sanity as well as the Chaotix's destruction of New Megaopolis's communications center, the various Sub-Bosses went unchecked as Dr. Eggman obsessed over defeating Sonic the Hedgehog, effectively ruling their own personal fiefdoms. After adding the former Dark Legion to his cyborg Mobian armies, Eggman renamed the various groups the "Dark Egg Legion", and most of his Sub-Bosses were renamed Grandmasters. (StH: #190, #194, #214)

Background Information

 * In one of his Q&A sections, Ian Flynn stated that all active Sub-Bosses (with the exception of the Iron King and Queen) would now be titled "Grandmasters", going off the Dark Egg Legion formula. (1)
