— Description, Sonic Adventure website[1]

The Egg Viper (エッグバイパー Eggu Baipā?), also known as simply the Viper,[2] is a vehicle that appears in the Sonic the Hedgehog series. It is a giant, viper-based combat machine created by Dr. Robotnik which was used by the doctor to battle Sonic during the Chaos incident.

Description[]

Appearance[]

In keeping with its name, the Egg Viper is designed after a large flying viper. It has two large red and gray spiked wheels on both side of the cockpit which the Eggmobile can fit inside. The cockpit itself is covered in thick red and gray armor and has two fins on the bottom, yellow and black hazard stripes horizontally along the middle, a single fin on top with a red and gray tube on each side, and a large gray laser cannon down the front which can slide back to reveal the pilot. On the cockpit's rear are three large red and gray flap-like shields. Beneath these shields are a long red and gray segmented tail which has spikes and green spots running down it.

Features and abilities[]

The Egg Viper's head and joints on its tail are equipped with a multitude of laser cannons which can fire intense laser beams, the most powerful which can cause small explosions. The shields that cover both the top and sides of the cockpit also have a mechanism that enables them to be moved and used in combat.[1] When moved into position, these shield can charge up concentrated bursts of energy and launch them at opponents (though such a maneuver leaves the Egg Viper without defenses). The Egg Viper can also detach its spiked wheels and thrust them through midair like spinning sawblades, which will then return to the Egg Viper like boomerangs.

Weapons aside, the Egg Viper is capable of flight through midair. It is also quite powerful and durable, being able to plow through several metal platforms without slowing down or taking damage.

History[]

Sonic Adventure[]

In Sonic Adventure, after braving the Final Egg, Sonic made it to the center of the base where Dr. Robotnik was waiting in the Egg Viper for their showdown. As the Egg Viper flew away, Sonic followed it to the battle arena inside the Final Egg's main tower using a rocket. There, Sonic and Robotnik engaged in an intense battle which ended when Sonic dealt the Egg Viper a critical blow that caused it to start blowing up. In a last-ditch attempt to claim victory however, Robotnik tried steering the failing Egg Viper into Sonic, but failed. After the Egg Viper exploded, Sonic and Robotnik escaped the Final Egg.

In Sonic Rivals, the Egg Viper appears on the 126th collectible card in the game.

Battle[]

The Egg Viper is the seventh and final boss of Sonic's storyline in Sonic Adventure and its enhanced port Sonic Adventure DX: Director's Cut. In Adventure Mode, it is fought after clearing Final Egg for the first time as Sonic. In Trial mode, it is the fifth and final boss in the Boss Sub Game as Sonic.

The Egg Viper is fought as Sonic by default. In Sonic Adventure DX: Director's Cut and the 2010 remaster though, it can also be encountered as Metal Sonic in the Boss Sub Game.

Boss guide[]

The boss battle against the Egg Viper takes place across two platforms above a bottomless pit in front of the Egg Viper. Each side of the platforms have a small set of Rings to be collected. Over the course of the battle, the Egg Viper uses different types of attacks according to its life gauge:

  1. The first attack pattern is firing four or five laser beams from its tail in a row. To avoid this attack, Sonic must keep moving in different directions to avoid being hit. Robotnik then simply reveals himself, allowing the player land the Spin Jump on him.
  2. The Egg Viper starts to charge and shoot an energy ball as its second attack. During the charging process, the cockpit exposes itself on the machine, giving Sonic a chance for attacking him. To damage him, Sonic can Homing Attack into the nodes on the Egg Viper's tail which leads up to the cockpit.
  3. The third attack pattern is shooting a powerful laser with the machine's laser cannon. First, the Egg Viper takes an aim at Sonic before firing. After a short time of moving, the cannon is fired and a quick reaction helps Sonic avoid it.
  4. When the life gauge reaches half, the Egg Viper flies over the platform where Sonic is standing and shoots laser beams at Sonic's position as Robotnik's gloats at him.
  5. The common attack pattern during the last half of the machine's life gauge is launching its razor discs. This can be used to damage the Egg Mobile too. To avoid this, Sonic must get as far away as he can or just jump when the disc comes close. Once the disc stops, he can jump on it to reach the Egg Viper's top and attack it with the Homing Attack or the Light Speed Attack.
  6. After destroying the platforms on the other side, the Egg Viper destroys a platform where Sonic is standing and shoots its razor discs again. This pattern is used until the life gauge reaches zero. If Sonic keeps missing his chances to hit Robotnik in this phase, he eventually runs out of platforms and falls to his death.

After Sonic has completely depleted the Egg Viper's life gauge, the machine will convulse uncontrollably and will attempt a suicidal attack, in which the Egg Viper will ram into the platform Sonic is standing on. A quick Spin Dash or Homing Attack is required. If it succeeds, it will kill Sonic alongside the machine and they both fall in the bottomless pit; this can be problematic if Robotnik has destroyed many platforms during his attack due to Sonic missing his chances to attack Robotnik. If only one platform remains by the time Robotnik attempts the suicide assault, Sonic's doom is certain. But once safely evaded, Sonic's story will be cleared.

Books and comics[]

Archie Comics[]

Trivia[]

Egg-EG3-Viper-Textures

Textures from the Egg Viper with the code name "EG3".

  • Like the Egg Hornet and the Egg Walker, the Egg Viper has the code name "EG3". It is displayed around the vehicle's gray and orange metallic parts.
  • The Egg Viper is similar to the Egg Wyvern. Both bosses are the same color, both are suspended above low ground, both battles have a part where the player attack Dr. Eggman head on, and both bosses destroy platforms and decrease the amount of space they have to run on.
  • Both the Egg Viper and the Egg Walker have become infamous for Robotnik's line, "Get a load of this!", which he repeats many times during their respective battles.
  • With a total of seven hits required to defeat it, the Egg Viper has the most health out of every boss in Sonic Adventure, even having more health than Perfect Chaos.
  • Of all the bosses, Egg Viper is the only boss, that is not from Gamma's story, that Gamma is able to lock-on and attack (if the player swaps the character, via a mod, to be playable in any location). All other bosses will not get hit by his lock-on attacks.[4]
