Egg Dragoon

The Egg Dragoon (エッグ・ドラグーン) or the Ultra-Hyper Prototype-1 is the final robot boss from Sonic Unleashed and third boss of Sonic Generations. Dr. Eggman developed it using the power supplied by Dark Gaia.

Sonic Unleashed
Upon completing the "Eggmanland" stage, Sonic the Werehog and Chip end up in the opening of a canal leading to the core of the planet. Eggman surprises the duo by revealing his latest creation: the new "Ultra-hyper Prototype 1," better known as the Egg Dragoon. The doctor promptly destroys the cover of the canal Sonic and Chip are standing on, forcing the two to seek a foothold on a chunk of metal. After a heated battle, Sonic manages to dislodge Eggman from its cockpit and disable the Egg Dragoon's propulsion system, causing the robot to fall and melt into slag in the planet's core. thumb|left|300px Though it is unofficial, it appears that Eggman has an early design for the Egg Dragoon used on his Star Cruiser. The torso of the original mech became part of the Egg Dragoon's "head".

Mobile version
In the Mobile Version of Sonic Unleashed, a version of the Egg Dragoon that is powered by Dark Gaia is the final boss and is fought in Mazuri.

Sonic Generations
For the boss of the game, please go to: Eggmanland (Sonic Generations).

The Egg Dragoon reappears in Sonic Generations as the Modern era's main boss. Heavily modified from the original version, this "Ultra-hyper Prototype 2" is modeled to outmatch Sonic's running speed, and is capable of displaying a wide variety of attacks while on the run (flamethrowers, freezebombs, drill projectiles, etc). It has two cockpits: One located in its head, and the other in its lower-belly. Throughout the battle, Eggman toggles between the two sets of controls, attacking using the machine's torso and legs respectively. In addition, this version of the Egg Dragoon can split into two independent robots.

This time, Modern Sonic fights the Egg Dragoon without his Werehog powers.

Characteristics
The Egg Dragoon was one of the most powerful of Eggman's robots. Its thick armor made its body impregnable even against Sonic's attacks, and it possessed a lethally efficient selection of weapons. Its power source was supplied by Dark Gaia.

The Egg Dragoon's weakness seems to be the orb at its bottom, as well as Eggman's cockpit.

Weapons and Abilities
On the Egg Dragoon's right arm is a massive energy cannon. Along the cannon's octagonal carapace, eight small barrels extend outward from the primary mechanism. These cannons rotate independently and at great speed, launching a barrage of energy blasts with every spin, similar to that of a Gatling gun. The inner part of this cannon holds an canister of supercooled gas that Eggman launches in a concentrated blast in attempts to freeze Sonic.

On its left arm, the Egg Dragoon holds a long and gigantic drill. With a sideways wave, the drill can release a massive wave of electrical energy at the Werehog. The drill can also be launched like a homing missile at its targets, and can drill through the arena easily. Amusingly, Sonic uses this against Eggman in the QTEs of the fight, since Eggman's drill ends up striking the orb on his machine.

The Egg Dragoon also has wing-like energy protrusions on its "shoulders" that allows it to hover.

Trivia

 * This is the only Eggman boss you fight using the Werehog.
 * The Eggman piloted robot from the intro to the game is similar in design to the Egg Dragoon.
 * If you fail to defeat Eggman at the final QTE where you throw him and end the fight, the Egg Dragoon will regain health back, but when you do the QTE again, the Egg Pod is still heavily damaged, and the cockpit's glass is broken.
 * The Egg Dragoon's attacks seems to give references to Sonic Unleashed's other night time bosses; The ice bomb refers to the Dark Moray, the fire bullets refers to the Dark Gaia Phoenix, and the electric swing with its drill refers to the Dark Guardian.
 * In Sonic Unleashed, when the Egg Dragoon is preparing to sweep the platform with the electrified drill, the word "danger" appears at the edges of the area to be swept.
 * The Egg Dragoon's power supply in Unleashed was energy from Dark Gaia; in Generations, this supply may be obtained from the Time Eater. Though, since the other bosses seem to be temporal distortions where the fight takes place in the same spot it did in its game of origin, the power supply may still come from Dark Gaia due to being located in the past.
 * The portals the Egg Dragoon goes through is similar to the ones the Time Eater creates. It is possible that classic Dr. Eggman was helping him during the fight, or modern Dr. Eggman infused some of it's power within it.
