Dr. Eggman, during the fight with Sonic .

The Egg-Genesis is a robot Dr. Eggman created and is a boss in Sonic the Hedgehog (2006). It has four arms, searchlights, and the ability of flight. It is only seen in Sonic and Silver Episodes as well as the Team Attack Amigo DLC stage. After two of its arms are destroyed, it fires its core laser if the player is caught in a searchlight. After all of its legs are destroyed, it will attempt to crash into the player.


The Egg Genesis is a titanic battle station that carries multiple mech battalions in its four massive arms. The metal monstrosity is loaded with multiple offensive weapons, including missile launchers on each arm and a homing laser that erupts from its under- carriage, the Egg Genesis’s weak spot.

Silver Episode

After beating White Acropolis, Silver fights the Egg-Genesis. Silver has to throw boxes and missiles at its core in order to destroy it.

Boss battle


At the beginning of the battle, the Egg Genesis rises into the air, closing its arms. When the player see the arms lock into a vertical position, start running, because it’s about to fire missiles at the player. The missiles are slow enough for the player to outrun them, but with four individual volleys in play, the player must avoid running away from one salvo and into another. While running from the missiles, be sure to pick up Rings.

There are two ways to beat this boss.

The first and official way is when Egg Genesis lowers down and spreads its arms to release robots, Sonic must then homming attack the robots to reach one of the arms, Sonic them must get to the Egg-Genesis' head all the while avoiding the missiles it fires and use the Bounce Bracelet on the head to do damage, after a few hits, one of the Egg-Genesis' arms will break off and Sonic will fly high into the air and land back on the ground, after the player destroy two of the four arms, the Egg Genesis employs the Core Laser attack after each unsuccessful missile volley. The machine rises back up into the air and paints Sonic with a red target. As soon as the player see the target, run! Egg Genesis locks on and tracks your movement right up to the moment it fires an orange energy laser, so if the player keep running, the player can outmaneuver the laser attack. The first few energy lasers release only a single beam. However, when all four of the arms are gone, the Egg Genesis powers up the energy laser for additional strikes. The laser now emits three beams, so keep running until the final laser blast hits the ground, also as it take damage it will hid it's head more and more frenetically. When the player are finally about to finish off the Egg Genesis, it makes one last desperation move. Knowing it is going to crash, the machine targets Sonic one last time and attempts to smash into him. If The player caught beneath the titanic battle fortress, the player will be crushed, so run to the arena’s outskirts as the player watch the damaged hull descend from the skies.

The second and easy way is to wait until the Egg-Genesis lowers down enough, as the orange core underneath is also the Egg-Genesis' weak point, when its weak undercarriage is close enough. Use Bound Jumps to get enough height to latch onto the orange sphere with a Homing Attack. Once the player hit the weak spot, attack repeatedly to cause enough damage for the machine to drop one of its arms. Every time the Egg Genesis sheds one of its arms, Sonic flies high above the machine. The player always land on the arena’s outskirts just in time to watch the Egg Genesis rise into position to fire off a missile salvo.


When the Egg Genesis closes its four arms and rises off the ground, it is getting ready to release a missile volley. The energy core is protected in this position. However, as the player cause damage to the Egg Genesis, the arms fall away one by one. Not only does this expose the core, but it decreases the number of missiles the monster can fire at the player. The heat-seeking missiles move slowly through the air. The player can use metal crates to deflect the missiles, but the player best defense is simply to run away as the missiles close in on your position. the player can use PK to grab the slow-moving missiles and fire them back at the Egg Genesis to cause damage.  After firing several missile volleys, the Egg Genesis resorts to using its Laser Attack. The machine rises into the air and spreads its arms to expose its core completely. This seems like the perfect opportunity to attack, but actually, you have no time to make an effective attack. A red sphere appears around the player, indicating that the Egg Genesis has locked on to the player position. Run as soon as the player see the sphere because the laser is about to fire. The Egg Genesis shoots a single beam early in the battle, and if the player stay in constant motion, the player can escape the lock just as the beam fires. Attacks to the core cause the most damage, but anything helps in this epic battle. Pick up crates with PK and throw them at the closed arms to chip away at the Egg Genesis’s defenses. Every quarter of its health bar that you chisel away destroys one arm. When the Egg Genesis has only one arm, it gets desperate and nasty. When it locks onto the player with its laser attack, the player must keep running even after the player see the first beam rush to the red sphere because several more beams are coming right behind the first. If the Egg Genesis hits you with even one beam, you’re toast. Just be careful while you’re trying to destroy its core, and you should be able to put the monstrosity down for good.

Team Attack Amigo

Omega fights the Egg Genesis in White Acropolis. Omega is used for this boss fight where he must use his Homing Missiles to attack the Egg-Genesis and the robots it sends out.


  • The Egg-Genesis' head bears an uncanny resemblance to those of the E-Series robots (specifically the E-100s).
  • The Egg-Genesis may be named after the Sega Genesis. The Sega Genesis was the console which the original Sonic the Hedgehog was on, along with Sonic the Hedgehog 2, Sonic the Hedgehog 3, Sonic & Knuckles, and multiple spin-off titles. This is further supported by the fact that Sonic the Hedgehog (2006) was made to celebrate Sonic's 15th anniversary.
  • When fighting the Egg-Genesis as Sonic, he can hit him on the weak spot he has when fighting him as Silver (under the middle). Sonic will still fly upwards after doing so like when you hit him on top of the head.
