Flying Eggman[1] (フライングエッグマン[2] Furaingu Egguman?), also known as the Egg Bouncer,[3] is an object that appears in the Sonic the Hedgehog series. It is a modified Egg Mobile created by Dr. Eggman, which has been used against Sonic the Hedgehog and his allies on several occasions.



Flying Eggman, from Sonic the Hedgehog 2.

Flying Eggman looks identical to the standard Egg Mobile, except that it is surrounded by seven ball pods that orbit it.

Features and abilities

Flying Eggman is capable of flight. It can also drop one of its ball pods and turn it into a balloon version of itself. In addition, it can shoot yellow lasers.

Game appearances

Sonic the Hedgehog 2

Flying Eggman II[sic] is shielded with orbiting spheres that turn into decoys before falling back on a powerful laser.

— Description, Sonic the Hedgehog Encyclo-speed-ia

In Sonic the Hedgehog 2, its various ports and remasters, and the lock-on game Knuckles the Echidna in Sonic the Hedgehog 2, Flying Eggman is fought at the end of Metropolis Zone Act 3, as well as Boss Attack Zone in the 2013 remaster. In the original game, it is fought with Sonic and Tails. In Knuckles the Echidna in Sonic the Hedgehog 2 and the 2013 remaster, it can also be fought with Knuckles.

The battle takes place on a flat platform. Here, Flying Eggman will arrive with seven small spheres orbiting itself. These ball pods protect Flying Eggman, causing damage to the player if struck, and move in complicated patterns. To begin with, the Egg Mobile 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 at the boundaries of the stage. Immediately after this is the best time to attack as the pods briefly orbit the Egg Mobile just around the middle rather than whirling all around it.

If the player hits the main body of the Egg Mobile, one of the ball pods will detach and expand into an inflatable copy of the Egg Mobile, while Dr. 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 Jump. Once the clone is destroyed, Dr. Robotnik drops down again and resumes his pattern. Once all of the ball pods/clones have been removed and destroyed, Dr. Robotnik will fly to one side of the screen and fire yellow laser blasts. Robotnik will keep doing this until the Egg Mobile is hit for the eighth and final time (seven hits are required to destroy the ball pods), which defeats Dr. Robotnik once again, who escapes, and the player can press the switch on the capsule to complete the zone.

When Knuckles faces Flying Eggman, the battle is notoriously more difficult due to Knuckles' poor jumping skills. Unless the player uses Super Knuckles, it is almost impossible to defeat the boss without getting hit.

Sonic & Knuckles

Flying Eggman makes another appearance as the second boss of Sonic's version of Sky Sanctuary Zone in Sonic & Knuckles and the lock-on game Sonic the Hedgehog 3 & Knuckles under the name Egg Bouncer.[3] Instead of Dr. Robotnik, Mecha Sonic pilots the Egg Mobile this time, with seven ball pods orbiting and protecting him. It is the twelfth boss overall of Sonic's story in Sonic & Knuckles and the twenty-fourth boss of Sonic and Tails' stories in Sonic the Hedgehog 3 & Knuckles. In Sonic & Knuckles, it is fought by Sonic. In Sonic the Hedgehog 3 & Knuckles, it can also be fought by Tails either alone or as Sonic's partner. It can also be fought by Knuckles if both Level Select and Debug Mode are enabled to allow him to play through Sonic's version of Sky Sanctuary Zone.

The Egg Bouncer uses the same attack pattern as its predecessor, as the player has to deal with all seven ball pods and their fake clones, which this time resemble Mecha Sonic in the Egg Mobile. Similarly, after this, Mecha Sonic moves to the corner while trying to shoot lasers from the machine. Like in Sonic the Hedgehog 2, the first seven hits come from hitting him and dealing with the clones and the last one finishes Mecha Sonic. The battle is much easier, as the player is now able to reach and hit Mecha Sonic, who floats around the top of the arena, while the fake ones float around elsewhere, no longer needing to be destroyed due to Mecha Sonic being within the reach of a Spin Jump. Furthermore, when playing as Sonic, the player can utilize the Insta-Shield to easily hit the Egg Mobile while protecting himself from getting hurt by the orbiting ball pods if the move is used at the right moment.

After defeating Mecha Sonic, who escapes again in his exploding Egg Mobile, a Warp Point appears in the arena's center that transports the player to the higher levels of Sky Sanctuary Zone.


  • It is possible for the player to fight this boss more than once if they fall off into the lower sections of Sky Sanctuary Zone and return to the boss arena.
  • In the original version of Sonic & Knuckles and Sonic the Hedgehog 3 & Knuckles, the Act 2 boss BGM would play when encountering this boss. This has been changed in the 2022 remaster of Sonic the Hedgehog 3 & Knuckles in Sonic Origins, which now plays the Act 1 boss BGM when encountering this boss.

Sonic the Hedgehog 4: Episode I

Dr. Eggman trots out the balloon-decoy-launching mecha from Sonic The Hedgehog 2's Metropolis Zone, with a few variations to spice things up.

— Description, Sonic the Hedgehog Encyclo-speed-ia

Flying Eggman made a reappearance in Sonic the Hedgehog 4: Episode I, where it is the fourth boss of the game at Mad Gear Zone but with clear differences. The first part of the fight is just like in the previous games with slight exceptions. The Egg Mobile in the fight is much larger and the ball pods' movement around him is somewhat different. The player is now also able to hit Dr. Eggman directly without releasing off his copies, but the hitbox of the mobile is mostly protected by the ball pods, which the player may hit instead. If the player hits one of the ball pods, 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.

If the player manages to hit Egg Mobile four times or destroys all of the ball pods, Eggman will run away by using large rockets below the mobile, while the player has to chase him. During the chase, Eggman himself will throw copies with different attributes. He will throw either normal ones, blue ones (that bounces much faster than normal) or a white-yellow one, that starts off small but expands to a giant size twice as big as the Egg Mobile itself. Eggman will also throw iron balls to the route as well. After four hits by using Homing Attack on him, the battle ends, as Eggman escapes and the player heads to the Capsule.

The boss battle reappears later in E.G.G. Station Zone, as part of the boss rush before facing the final boss. It is mostly the same chase sequence with identical patterns, while the Egg Mobile can be taken down by doing four hits to him. During the last hit, large hatches on the spaceship starts to open up. After the defeating boss again, the player heads to the last Star Post and the final boss of the game.
