The Egg Mobile (also known as the "Egg-O-Matic" or Robo/Egg Pod) is a one-person, multi-purpose hovercraft used by Dr. Ivo Robotnik, and later his alternate-future counterpart Dr. Eggman as a personal means of transportation and attack craft. The Egg Mobile can be fitted with a wide array of weapons and also serves as the cockpit for larger machines, as well as an escape pod when they are inevitably defeated by Sonic the Hedgehog and/or his allies.
