The Egg Carrier (エッグキャリア Eggu Kyaria?) is a fictional flying fortress created by Doctor Eggman in the Sonic the Hedgehog series of video games. It appeared first in the game Sonic Adventure. It was modeled after Aerial Strike Vessel/Multi-functional Flying Fortress. It is a large, armoured aircraft with red, yellow, black and white coloured hull, super laser cannon, turret laser cannon, air mines and missile launchers.
Similar flying fortresses have been a staple of Sonic the Hedgehog games for a long time, the very first one being the "Sky Base Zone" in Sonic the Hedgehog for Game Gear. The most widely known airship stage, however, was the "Wing Fortress Zone" in Sonic the Hedgehog 2. They have reappeared (often with different names) in many games since - one zone in Sonic & Knuckles was aboard a flying fortress called the "Flying Battery", and another in Sonic the Hedgehog Pocket Adventure which was aboard the "Aerobase".
