Egg Carrier

The Egg Carrier is a large flying fortress which belongs to Doctor Eggman, armored and equipped with several energy cannons, missile launchers, and air mines. The vessel is capable of structural transformation, for both offensive and defensive purposes; however, this ability is not shown in the "Dimension" saga. Instead, the Doctor uses several Egg Carriers to combat the hijacked Egg Bomber Ship while in Frogger's dimension—using the vessels' many energy cannons in an attempt to destroy the alliance of heroes. The battle ends with all of the Egg Carriers either disabled or destroyed (that which was disabled and crashed in the Garden would be used by Mr. D later on). In the War Above Earth, more Egg Carriers join the Doctor's new fleet above the planet, piloted by Egg Robos; though the energy cannons and missile launchers are used consistently to protect the Death Egg and stop the Star-Moon/Irken Armada, ultimately the vessels are overpowered, as the Doctor's entire fleet is depleted.

Despite the Doctor being imprisoned in Zim's dimension following said events, two more Egg Carriers are used five years later, during the Preliminary Xevian Attacks —one by the alliance of heroes to rescue Zim, and the other by Mr. D to capture Frogger and find the sacred elements. Both are eventually destroyed by the Xevians, though no one is inside either of them.
