For the boss that appears in Act 1, see Doctor Robotnik's Flame Craft (Angel Island Zone Act 1).

Doctor Robotnik's Flame Craft[1] (フレイムモービル[2] Fureimu Mōbiru?, lit. "Flame Mobile") 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.




Dr. Robotnik's Flame Craft 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 Flame Craft's design is simplified. Here, it is much smaller, about the same size as the standard Egg Mobile. Its cannons are much smaller as well and are cylinder-shaped. The dome on the bottom of the Flame Craft is also crimson instead of orange.

Features and abilities

The Flame Craft 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 Flame Craft 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 Flame Craft and confronted Knuckles with it. However, the vehicle was nothing in comparison to the echidna, and the Flame Craft was destroyed again.

Other game appearances

Sonic Jam (

In Sonic Jam (, the Flame Craft appears as one of the bosses in Angel Island Zone.

SEGA Heroes

In SEGA Heroes, the Flame Craft returned as one of the three mobiles Dr. Eggman could pilot.


Doctor Robotnik's Flame Craft is the boss of Angel Island Zone 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 if he/she is playing as Sonic the Hedgehog and/or Miles "Tails" Prower, while in Sonic the Hedgehog 3 & Knuckles, the player also encounters the boss while playing as Knuckles the Echidna.

Boss guide

The Flame Craft first appears moments after the player outruns the bombs dropped by the Flying Battery. It flies past the player in the Act's background, before disappearing behind a huge waterfall. When Sonic crosses a wooden bridge, the Flame Craft emerges through the waterfall and drops a fireball on the bridge, destroying it. The player is able to fall into a bottomless pit if the playable character is standing on the bridge when it is destroyed.

The Flame Craft will then disappear behind the waterfall, becoming impossible for Sonic to hit, and emerge again in a new location to fire its weapons at Sonic 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 Attack on it again during those times. After eight hits, the Flame Craft will be destroyed, and the player will be able to proceed to the Capsule and finish the Zone.

When playing as Knuckles in Sonic the Hedgehog 3 & Knuckles, the player enters the arena from a different pathway. An EggRobo is seen piloting the vehicle using a similar pattern of attack, but is able to fire four fireballs at one time. After landing eight hits on the vehicle, the player will be able to proceed to the Capsule and finish the Zone.

In other media

Sonic Adventures

The Flame Craft as it appears in Sonic Adventures.

In Sonic Adventures, the Flame Craft appears as Dr. Robotnik's main transportation vehicle instead of the regular Egg Mobile. While not having the important role in the story, the arm cannons have motors behind them and function as flamethrowers instead of launching fireballs.


  • The Flame Craft appears on the US box art for the Sega Genesis version of Sonic the Hedgehog 3. Like in Sonic Adventures, Robotnik is seen firing flames instead of fireballs in the box art.
  • In the end credits for Wreck-It Ralph, Sonic is seen losing his Rings, when Eggman in the Flame Craft 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.
