The Egg Scorcher Mk III[1] (フレイムモービル[2] Fureimu Mōbiru?, lit. "Flame Mobile"), also known as Doctor Robotnik's Flame Craft,[3] is a vehicle that appears in the Sonic the Hedgehog series. It is a weaponized hovercraft that was used by Dr. Eggman during the first part of the Angel Island incident.




The Egg Scorcher Mk III is a single-person, sphere-shaped hovercraft. It is dark blue in color and is equipped with two large, steerable cannons on either side. It also has a small orange dome on the bottom of the main pod.

In SEGA Heroes, the Egg Scorcher Mk III's design is simplified. Here, it is much smaller, about the same size as the standard Egg Mobile. Its cannons are smaller and shorter as well and are cylinder-shaped. The dome on the bottom of the Egg Scorcher Mk III is also crimson instead of orange.

Features and abilities

The Egg Scorcher Mk III is capable of flight. It can also fire intense fireballs.


Sonic the Hedgehog 3 & Knuckles

In Sonic the Hedgehog 3, and its lock-on version Sonic the Hedgehog 3 & Knuckles, Dr. Robotnik used the Egg Scorcher Mk III during an attempt to exterminate Sonic the Hedgehog and Miles "Tails" Prower when the duo began to interfere with his plans in Angel Island Zone. However, the doctor and his vehicle were defeated by the two heroes.

Later, an EggRobo piloted a rebuilt Egg Scorcher Mk III and confronted Knuckles with it. However, the vehicle was nothing in comparison to the echidna, and the Egg Scorcher Mk III was destroyed again.

The Egg Scorcher Mk III is the boss of Angel Island Zone Act 2 in both Sonic the Hedgehog 3 and Sonic the Hedgehog 3 & Knuckles and the second boss overall in those games. In Sonic the Hedgehog 3, the player encounters this boss as Sonic the Hedgehog and/or Miles "Tails" Prower, while in Sonic the Hedgehog 3 & Knuckles, it can also be encountered while playing as Knuckles the Echidna.

Boss guide

The fight commences when the player crosses a wooden bridge; the Egg Scorcher Mk III emerges through the waterfall and drops a fireball on the bridge, destroying it. This creates a bottomless pit which will cause the player to lose a life if the playable character falls into it.

The Egg Scorcher Mk III will then disappear behind the waterfall, becoming impossible for the player to hit, and emerge again in a new location to attack the player again. Robotnik will move in certain patterns, either to the far right, upper left corner or left side. Robotnik will fire two fireballs each time it emerges, and Sonic will only be able to use the Spin Jump on it again during those times. The fireballs will not hurt the player if they have a Flame Shield equipped. After eight hits, the Egg Scorcher Mk III will be destroyed, and the player will be able to hit the Capsule descending from above and finish the Zone.

When playing as Knuckles in Sonic the Hedgehog 3 & Knuckles, the fight against the Egg Scorcher Mk III piloted by an EggRobo is nearly identical, but it will also sometimes fire four fireballs at once.

  • The Egg Scorcher Mk III appears on the American boxart of Sonic the Hedgehog 3. Here, it is seen firing flames instead of fireballs.
  • In the end credits for Wreck-It Ralph, Sonic is seen losing his Rings, when Eggman in the Egg Scorcher Mk III appears in surprise in Chemical Plant Zone.
  • If the player is playing as Sonic and Tails and Sonic goes for the early hit when Robotnik destroys the bridge and gets Tails stuck behind the boss, Tails will bounce between the locked screen and the boss, defeating it within a few seconds.
