Great Blue Realm

The Great Blue Realm encompasses all or part of the planet Mobius' oceans, and is known to include the undersea city of Meropis. It is also home to an aquatic division of Dr. Eggman's Egg Army, under the command of Egg Boss Akhlut. It was one of many areas of the planet affected by The Shattered World Crisis, and was thus besieged by Dark Gaia's Minions (StH: #261)
