Egg Carrier/Pre-SGW

The Egg Carrier was a large airship created by Dr. Eggman, and an important transport for the doctor during an attempt to conquer Station Square. The Egg Carrier was crewed by Eggman and various robots, including the first E-100 Series robots, and the most notable of them, E-102 Gamma. The original Egg Carrier fell into the ocean after a mighty battle and burst into flames. Shortly after, a second Egg Carrier was made to stop the rampage of Perfect Chaos, but the creature destroyed the ship with an energy blast.

The Chaos Crisis
Eggman first used the Egg Carrier to find and destroy the Master Emerald on Angel Island in order to free Chaos. After succeeding, the Egg Carrier landed in the Mystic Ruins for later usage. Meanwhile, this carrier would be used as a base of sorts, where he sent the E-100 series to locate a certain amphibian life form, and where Amy Rose was taken to when she and a Flicky were abducted by two of Eggman's robots. Both tasks were seemingly crucial to restoring the creature known as Chaos. After fleeing from Sonic, Tails, and Knuckles, Eggman decided to take the Egg Carrier out of its hiding place in a very wide river (unknowingly allowing Big the Cat to get aboard).

Undaunted, Sonic and Tails used the Tornado to get aboard, and Knuckles was warped there after receiving a vision from Tikal. Knuckles and Big found what they were looking for, and Amy managed to escape from her cell, thanks to E-102. On the deck, Sonic and Tails defeated E-102, when suddenly the ship started losing altitude, so Tails, Amy and E-102 fled the ship. Sonic stayed to find Eggman, which he did, along with Chaos. Sonic, Knuckles and Big all fought and defeated Chaos, and everyone fled the ship as it crashed into the ocean below and burst into flames. (StH: #80, #81, #82, SSS: #13)

Second Model
After Chaos obtained all seven Super Emeralds and became Perfect Chaos, Eggman revealed a second Egg Carrier ship refered to as the "Eggship Destroyer" by Knuckles, which was a failsafe to use against Chaos in case it rebelled. However, the ship proved to be nothing compared to the power of Perfect Chaos, who shot it down with a large energy beam. (StH: #83)

Abilities
The Egg Carrier could transform into two shapes; offensive and defensive. While being somewhat streamlined in its offensive shape, the defensive shape folded the wings out to the sides and makes it much harder to get from the landing area to the bridge. The second mode also made the ship a massive airborne drill, which Eggman hoped to use to break through the mountain hiding Station Square.

Background information

 * The Egg Carrier was based off its video game counterpart from the game Sonic Adventure.
 * In the games, the second ship is called the Egg Carrier 2, which is considered Tier 2 canon by this site's canon policy.
 * Despite the game version having a plethora of weaponry to use against Sonic and Tails, it only used missile launchers, thus it is unknown if it also had other weapons.
 * The above Background Information is only connected to the pre-Super Genesis Wave universe, as it is assumed that the events of Sonic Adventure played out normally in the post-Super Genesis Wave universe.
