Nega-Wisp Armor

"This robot is special. He's powered by the energy from your little friends. He is invincible. So I'd say it's been nice knowing you... but it hasn't."

- Eggman

thumb|right|300px|The battle with the Egg Nega Wisp on WiiThe Egg Nega Wisp (エッグネガウィスプ ) (Also called Nega Wisp Armor in the DS version) is the Final Boss of Sonic Colors, this boss is the first 3D Final Boss to not have Super Sonic as an obligatory transformation. A giant robot, piloted by Dr. Eggman, who uses the powers of the Wisps like Sonic but can use with more intensity and can combine them at his will. For doing so, the Doctor needs to harvest Wisps constantly through the battle.

Final Boss Part 1 Egg Nega Wisp
It fires the Cube power to launch cubes at Sonic, Spikes to launch spikeballs in the ground, and Laser to fire laser from its hands, it will also combine the Cube and Spikes together to make Spikes come to you, and the Laser with Cube to make the laser reflect at the cubes and hit you, it will also use Frenzy to get far from Sonic.

When it needs to use another attack, the arms will suck up nearby Wisps into itself through the giant hands. The only weak spot is if Sonic peforms a homing attack chain going up its arm and strikes at Eggman in the cock pit. At points during the boss battle, Sonic will recover the color Wisps that Eggman used to his side, but they merely float alongside him. When it is on the brink of defeat, Sonic combines all the color Wisps he's saved to perform a combination attack called the Final Color Blaster to finish the Egg Nega Wisp and send Eggman flying.

Final Boss Part 2 Egg Nega Whisp

 * Unlike the Wii Version, in the DS version, when Sonic saves a colored Wisp from the ENW, the ENW loses that power of that colored wisp and when all the Wisps are saved, he uses a suicidal assault by using a black hole cannon that he was hiding in his mouth.
 * Unlike the Wii Version, the DS version's Egg Nega Wisp has only one arm instead of 2.
 * During the Wii battle, the announcer sounds perfectly normal, but in the DS version, the announcer gets an eerie, distorted voice.
 * Unlike most other final bosses, this boss has an extra stage after it.
 * The Egg Nega Wisp is similar in appearance to the Sand Scorpion from Sonic and the Secret Rings. Interestingly enough, the method of attacking them is similar as well, as with the Sand Scorpion you had to use the Homing Attack to move up its tails to hit the eye on its back, whilst with the Egg Nega Wisp, the method is the same except performed on the arms to reach the head instead.
 * The cyan laser is the only wisp power that the Egg Nega Wisp uses in both versions of the game.
 * The ENW has a resemblance to the Pokèmon Hydreigon.
 * The head of the ENW somewhat resembles Sonic's.
 * In the DS version, the cyan laser attack bounces off walls similar to how Sonic uses it.
 * When the ENW recharges, it seems to only suck up White Wisps and soon converts them to Nega-Wisps
 * You can attack the Egg Nega Wisp a second time by boosting into its body after attacking the head, similar to the Egg Beetle. You also gain rings to collect and 1 wisp.
 * Another name for the Egg Nega Wisp is the Nega Wisp Armor, the term used in the DS version of Sonic Colors. In the Wii version, they never said the name of it.
