Dr. Eggman, Sonic the Hedgehog (2006)

The Egg-Wyvern, also spelled as Egg Wyvern, is the final boss in Sonic's story in Sonic the Hedgehog (2006). The Egg-Wyvern is a large robot that is similar to the creature of the same name: a breed of giant dragon native to Africa. It is completely red with spots of silver, white, and black here and there. Its lower jaw is actually the Egg Mobile used throughout Sonic the Hedgehog (2006) that is simply attached to the robot's neck.


The Egg-Wyvern only made an appearance in Sonic's story as the final boss. After Sonic made it to Eggman's cockpit to rescue Elise, the doctor had finally lost his final straw and decided that it was time to end it right then and there. Eggman attached the Egg Mobile to the Egg-Wyvern and charged at Sonic outside the Egg Carrier. In the end, Sonic was able to defeat the robot and send Eggman spiraling into the sky on his detached seat.


The Egg-Wyvern has a decent assortment of weapons. It uses its whole body as a weapon in the boss battle with him as it is able to charge at Sonic in the hopes of taking him out. The glowing red horn on its head may however have been the real thing that was to serve as a weapon despite the fact that all Sonic had to do was strike at it with a Homing Attack to latch on. It fires a random assortment of lasers down at Sonic from the laser emitters on its wings. It will strike with the wing lasers in hexagonal or rectangular patterns, or attempt to target Sonic directly. At another point it flies around the platform and remotely commands the Egg Carrier to fire large red plasma blasts at Sonic. And throughout the course of the battle it fires electric dart projectiles from its tail that are able to take out the platforms Sonic stands on.

Boss guide

When the battle begins, run around the platform to pick up Rings while Dr. Eggman gets in position to buzz the player from overhead. Gather these Rings sooner rather than later, since the platform shrinks throughout the battle. Your goal in this battle is to wrest control of the Egg-Wyvern. When Dr. Eggman strafes the platform, he flies low enough to clip Sonic. Hit the head with a Homing Attack. Sonic jumps up and grabs the horn at the nose of the Egg-Wyvern. If the player is badly hurt or just need a momentary break, you can also run away when Dr. Eggman strafes the platform. The player can hold on for just a few passes over the platform before Eggman regains control of the ship from the player.  While the player has gained control of the Egg-Wyvern, damage it by steering it into the falling cruiser cargo. The cruiser is already at critical speed, shaking loose giant fuel canisters. If the player gets the Egg-Wyvern to hit one of the canisters, the Egg-Wyvern bucks like a bull, knocking the player back to the platform while Eggman rights the controls and comes around for another pass.

When the Egg-Wyvern hovers near the edge of the platform and raises its wings like a bird trying to slow down for a landing, watch out for one of two attacks. If the player see red target reticles appear on the platform, move away and brace for a wing laser attack. Should one of the lasers hit the player, the player Rings are ejected with such force that most will probably fly off the platform. The other attack the Egg-Wyvern makes from this position is even more potent. Dr. Eggman fires two electric darts at the platforms. When the player see the electricity crackling around the platform, back away because that section of the platform is about to fall. If the player fails to move in time, the player will tumble to the earth below and that’s a long way down. When he circles the platform, Dr. Eggman remotely commands the receding Egg Carrier to rain down massive blasts of plasma down at Sonic.

After the player successfully steers the Egg-Wyvern into fuel canisters three times, the canopy (the top of the Egg-Wyvern's head) falls off, leaving Dr. Eggman exposed. Dr. Eggman tries a different strategy. Instead of buzzing the platform (or what’s left of it), he shoots two powerful lasers at the player. With limited space to run, the player must get uncomfortably close to the platform’s edge to avoid being shot. However, this laser attack proves to be Dr. Eggman’s undoing. He extends the cannons too close to the platform, giving the player a chance to use a Homing Attack to bounce off one of the cannons and strike the cockpit. After three more hits, Dr. Eggman will sweep in for a final attack, in which the player must use another Homing Attack to finish him.


  • It is possible to finish the battle in less than one minute by utilizing the Sky Gem. If the player throws the Gun Drive just a little before grabbing the Egg-Wyvern's antenna, the camera will zoom in at Sonic's direction with no way to change it or to see the robot. After some seconds, the result screen will appear.
  • The Egg-Wyvern boss battle reminds many fans of the Egg Viper boss battle from Sonic Adventure. The reasons may be due to the color of the robots, the high elevation, the destruction of platforms, certain points where the player is able to hit Eggman directly, and the fact that they are both final bosses.
    • At some points during the Egg-Wyvern battle, Eggman will say "Can you make it here?!", similar to a line when fighting the Egg Viper: "Let's see if you can make it through here, Sonic!". Both of these quotes occur when you have to use the Homing Attack to reach Eggman.
    • In addition, the Egg-Wyvern may be a throwback to a similar boss concept for Sky Chase. The key difference between these battles is that Sonic is on suspended platforms surrounding the Egg Carrier, whereas the Sonic Adventure version would have likely been a minor boss for the Tornado.
  • The Egg-Wyvern is the only final boss of Sonic the Hedgehog (2006) which is not fought multiple times in the story, unless one counts Solaris as a separate entity from Mephiles and Iblis; Iblis is fought at the beginning and end of Silver's story, and Mephiles is fought both midway and at the end of Shadow's story.
  • The Egg-Wyvern is very similar in design to the Egg Hawk, Egg Falcon, Egg Eagle and the Egg Dragoon.
