For other uses of the term, see Egg Dragoon (disambiguation).

Eggman created this mechanical dragon in his efforts to thwart Sonic, putting years of research into the hedgehog's movements patterns to use in its design. It represents the absolute pinnacle of mad science.

— Description, Sonic Unleashed (Xbox 360/PlayStation 3)

The Egg Dragoon (エッグ・ドラグーン Eggu Doragūn?), also referred to as the Ultra-Hyper Prototype-1[1] (ウルトラハイパー・プロトタイプ第1号 Urutorahaipā Purototaipu Dai 1 gō?), is a vehicle in the Sonic the Hedgehog series. It is a large dragon-based mech created by Dr. Eggman for the purpose of defeating Sonic the Hedgehog. It represents the absolute pinnacle of mad science.[2]

The Egg Dragoon is an imposing red mecha with design similarities to that of a dragon. Highly detailed, it has a bulky humanoid torso with spiked shoulder guards, several highlights on the front, a smaller platform-like torso inside the main torso for the Egg Mobile to be inserted into as a cockpit, blue prongs on its lower chest, thin arms, two wing units and exhaust pipes on the back. On its left arm it has a long and gigantic drill, and on the right arm it has a six-barreled cannon. Along the cannon's hexagonal carapace, its small barrels can extend outward from the primary mechanism. Its shoulder joints also have a spike protruding from each of them. Also, on the bottom of its upper torso dangles a lower-belly with two smaller cores (the lowest of which has protrusions on the side) and two talon-like feet cannons.

The first Egg Dragoon's wing units consisted simply of blue energy protrusions that formed wings. The second model had frames added to its wings, but they were not attached to the body. Also, its lower-belly initially consisted of lights, but would be redesigned as an additional cockpit for the second model (with the lowest one having the exhaust pipes on its side replaced with spikes). The second model also had a tail added to it.

The third known Egg Dragoon model looked much like the second model, but with silver spikes instead of black in many places, and had red energy wings instead of blue.

Features and abilities

The Egg Dragoon is one of Eggman's most powerful and versatile creations to date, its design being derived from years of research on Sonic the Hedgehog's movements patterns.[2] Its thick armor makes most of its body impregnable even against Sonic's attacks, and it possesses a lethally efficient selection of weapons that harness fire, lightning and ice elements. It also has enough physical strength to tear apart ground and rock with ease. In addition, it possesses wing units on its back that allow it to fly, and its drill can be launched as an electrically-charged homing missile (which the Egg Dragoon can reload without limit) that can easily pierce through meter-thick metal. Also, even without a pilot, the Egg Dragoon is capable of operating on its own.

The first Egg Dragoon channeled the majority of its element powers through its massive cannon. This cannon rotated independently at great speed, launching a barrage of fireballs with every spin, similar to that of a Gatling gun, which could set the ground ablaze. The cannon could also focus ice into a concentrated blast which could freeze anything solid upon contact. With its left drill-arm, it could also release a massive wave of electrical energy with a single swing.

The Egg Dragoon's Separation Attack, from the console/PC version of Sonic Generations.

The second and third Egg Dragoon were heavily redesigned with more lethal capabilities. Its cannon had been upgraded so it could spew multiple beams of fire over a wider range, and its feet had been turned into ice cannons, allowing it to not only fire rapid ice blasts, but also freezing waves along the ground. Its drill had also been upgraded so it could create electrified explosions upon impact when fired as a missile.[3] Most noticeably however, it possessed a much more modular design that allowed it to change shape. Its body could split into two independent robot units for two-pronged attacks (dubbed the "Separation Attack"), and its arms could be reconfigured into massive blocks for flattening foes. Its modular design also allowed Eggman to toggle between its two sets of cockpits, enabling him to attack using the machine's torso and legs respectively. This version also proved itself incredibly fast, easily keeping up with even Sonic's running speed.


Sonic Unleashed

In Sonic Unleashed, the Egg Dragoon was created by Dr. Eggman during the Dark Gaia incident to thwart Sonic. For its creation, Eggman used years of research into Sonic's movements patterns and the energy he harnessed from Dark Gaia.[1][2] After Sonic the Werehog and Chip activated the Gaia Temple in Eggmanland, Eggman ambushed the duo with his Egg Dragoon and had it destroy the cover of the canal Sonic and Chip stood on, sending them tumbling down to the core of the earth where they were forced to seek foothold on a chunk of metal. There, Eggman commandeered the Egg Dragoon into a heated battle with Sonic, who tore the mech apart with his Werehog strength and left it to fall and melt into slag in the planet's core.

Sonic Generations

In the console/PC version of Sonic Generations, a heavily re-modified Egg Dragoon with a wider arsenal was used by Dr. Eggman for a rematch with Sonic when the hedgehog entered the time frame of the Dark Gaia incident. Despite taking Sonic by surprise with the Egg Dragoon, the mech was still destroyed by Sonic's hands.

Sonic Forces

In Sonic Forces, the Egg Dragoon Mk. II[4] was summoned by Dr. Eggman when the doctor did battle with Classic Sonic. Piloting the Egg Dragoon, Eggman fought the otherworldly hedgehog, who used rocks to damage Eggman's mech. Eventually, the Egg Dragoon could not take more and blew up, although not before Eggman escaped it.

In the Sonic the Hedgehog comic series and its spin-offs published by Archie Comics, the Egg Dragoon debuted in Sonic the Hedgehog #285. During the Sonic Unleashed adaptation (the Shattered World Crisis), Dr. Eggman created this robot to combat Sonic the Hedgehog while the hedgehog was on a rescue mission to save Chip and retrieve the Chaos Emeralds.

Sonic fighting the Egg Dragoon, from Sonic the Hedgehog #1.

In the Sonic the Hedgehog comic series and its spin-offs published by IDW Publishing, the Egg Dragoon is presented as one of the many Eggman mechs that Sonic has fought over the years. Its past is virtually identical to its game counterpart's, up until after the events of Sonic Forces.


  • The Egg Dragoon's name is the term for a type of soldier that was trained to fight either on horseback or on foot. The term came from "dragon," which was a nickname for the guns used by Dragoons in the French Army. The words origin and similarity to "dragon" have caused the two to become almost related in the world of fiction. Fantasy dragoons usually carry a dragon motif, which would explain the dragon wings and the claw-like feet on the machine.
  • In the cutscene before the fight in the Wii/PlayStation 2 version of Sonic Unleashed, the cutscene uses the lighting of the Wii/PlayStation 2 version even though it is pre-rendered.
  • The Egg Dragoon's elemental attacks in Sonic Unleashed seem to give references to the game's other night time bosses; the ice bomb refers to Dark Moray, the fire bullets refer to the Dark Gaia Phoenix, and the electric swing with its drill refers to Dark Guardian.
  • The portals the Egg Dragoon goes through in the Sonic Generations battle are similar to the TIme Holes the Time Eater uses. It is possible that the Time Eater was helping the Egg Dragoon during the fight.

The early version of the Egg Dragoon, from the Xbox 360/PlayStation 3 version of Sonic Unleashed.

  • It appears that Eggman had an early design for the Egg Dragoon which was used on his star cruiser during the opening cinematic of Sonic Unleashed. The torso of the original mech became part of the Egg Dragoon's "head". Its armaments consisted of wrist mounted Gatling guns on each arm and retractable missile launchers on the back. Its arms also doubled as grappling hooks.
  • In all three games where the Egg Dragoon is fought, it is fought using a different version of Sonic each time. The Sonic Unleashed version is fought with Sonic the Werehog, the Sonic Generations version is fought with Modern Sonic, and the Sonic Forces version is fought with Classic Sonic.
