The fictional villain Dr. Eggman from the Sonic the Hedgehog series of video games has used several gigantic combat aircraft in his quest for world domination. 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".
