Flying Eggman (フライングエッグマン?) is the name of the boss fought in act three of Metropolis Zone from Sonic 2. It is controlled by Dr. Robotnik. This boss also reappears in Sonic & Knuckles and its locked-on form, Sonic the Hedgehog 3 & Knuckles, in Sky Sanctuary Zone as a sub-boss.
Although it is just Dr. Robotnik in his Eggmobile, Robotnik has seven fake forms of him that he releases from ball pods (in Sonic the Hedgehog 2). Robotnik is in the biggest Eggmobile, while the others can be defeated easily.
Sonic the Hedgehog 2Edit
This boss is basically Dr. Robotnik (Mecha Sonic in Sonic & Knuckles) with seven small spheres orbiting his Eggmobile. These spheres protect the Eggmobile, causing damage to the player if struck, and move in complicated patterns. To begin with, the Eggmobile descends and moves from left to right along the floor, forcing the player to make difficult jumps over it. After this, it will hover in the center and cause its pods to whirl around in very large circles, which the player can avoid if standing to the very side. Immediately after this is the best time to attack as the pods briefly orbit the Eggmobile just around the middle rather than whirling all around it. If the player hits the main body of the Eggmobile, one of the spheres will detach and expand into an inflatable copy of the Eggmobile, while Robotnik himself flies to the top of the screen, out of reach. The clone will float towards the player, and can be easily destroyed with a Spin Attack. Once the clone is destroyed, Robotnik drops down again and resumes its pattern.
Once all of the spheres/clones have been removed and destroyed, Robotnik (or Mecha Sonic) will fly to one side of the screen and fire lasers. This will continue until the Eggmobile is hit for the 8th and final time (7 hits having been required to destroy the spheres), which destroys the boss and completes the level.
The reappearance of this boss in the Sky Sanctuary Zone used exactly the same attack pattern.
Sonic the Hedgehog 4: Episode IEdit
This boss reappears in Sonic the Hedgehog 4: Episode I, in the Mad Gear Zone and E.G.G. Station Zone, but with clear differences. The first part of the fight is just like the others, but the player is able to hit Dr. Eggman without setting off the copies. If the player hits one of the bubbles, they'll come off and try to hit the player, but unlike Sonic the Hedgehog 2 and Sonic & Knuckles, the player will sustain damage if they try to destroy the copies. After the fight with the player, Eggman will run away much like the Eggmobile (retreat). While running away, Eggman will drop copies of himself with different attributes; for example one bounces much faster than normal, while another starts off small, but expands in varying sizes even to something twice as big as the Eggmobile itself. Eggman will also throw spike balls as well. The player has to hit Eggman with a Homing Attack three times to win the battle.
- When Knuckles faces this boss in the Knuckles the Echidna in Sonic the Hedgehog 2 lock-on version, the battle is notoriously difficult due to Knuckles' poor jumping skills. Unless the player uses Super Knuckles, it is impossible to defeat the boss without getting hit.
- This machine appeared in Archie Sonic the Hedgehog Issue 229.
- The clones do not appear exactly like the original Robotnik, as their mustaches droop a little further down.
