Egg-Genesis

"Begin charging core laser! Take this, Sonic!"

- Dr. Eggman, during Sonic's story.

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's story. 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.

Official Description
''"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. When the beast spreads its arms to release robots, it lowers to the ground long enough for Sonic to jump up and smash the orange sphere with a Homing Attack. Each successful round of attack causes the Egg Genesis to lose one of its four arms. This decreases the number of missiles the machine can unleash, but Egg Genesis makes up for the loss with even more powerful laser attacks." ''

Sonic's Story
After Radical Train is beaten, Elise jumps off of the Egg Mobile and Sonic catches her. Eggman sends the Egg-Genesis to capture Elise. Sonic destroys all of its arms and defeats it. To destroy it, Sonic must either get onto one of its arms and attack the head or use the Bounce Bracelet when the genesis is close to the ground to reach the core on the bottom of the machine.

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

Team Attack Amigo
The Egg-Genesis is fought at the end of the downloadable Team Attack Amigo. It is the ninth stage played after one has played through Tails, Blaze, and Omega's levels. Omega fights 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.

Trivia

 * 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.
