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

The Egg Nega Wisp, also known as the Nega-Wisp Armor in the DS version, is the final boss of Sonic Colors, this boss is the first 3D Modern Sonic 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 darkness, and can combine them at his will. For doing so, the Doctor needs to harvest Wisps constantly through the battle.

Apperance
The Egg Nega Wisp resembles a large robotic purple Wisp with sharp pointed spines along the body and a large one over the cockpit, clear colored frowning eyes, a large razor sharped mouth with two sharp spines on either side facing upright, a cannon inside that fires blue balls of spikes, small stubby legs around the frount and sides, a long tail out the back, and two large tetacles with sharp pincers on each end that contain a pair of purple eyes making the pincers look more like mouths which it uses to fire lasers and cubes from and also to harvest Wisps from nearby with a vaccum inside the arms that sucks them into large tanks located on it's back. The tanks change color depeding what ever action it is performing. The cockpit is located at the front just above it's eyes with a red arrow in front pointing down towards it's mouth.

Battle
thumb|right|250px|The battle with the Nega-Wisp Armor on WiiIt fires the Cube power to launch Cubes at Sonic, Spikes to launch Spike balls in the ground, and Laser to fire Laser from its hands, it will also combine the cube and spike 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,and possibly make it activate its wisp powers, due to at the beginning of the battle you hear the announcer say "Frenzy!" and probably, although its not proven, that it uses Hover and/or maybe Rocket to make the ENW float. Drill is unknown how it is used for it, considering the fact that it uses almost every wisp to make it function.

The only weak spot is if Sonic performs 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.

Trivia

 * Unlike the Wii Version, in the DS version, when Sonic saves a colored Wisp from the NWA, it 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 Nega-Wisp Armor 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.
 * In the Wii version, boosting into the ENW after homing attacking it will make it take more damage and will drop more rings, and you actually have to do this in order to cause extra damage.
 * 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 Nega-Wisp Armor, 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 ENW uses in both versions of the game.
 * The ENW has a resemblance to the Pokèmon Hydreigon.
 * The music played at the beginning also resembles that when battling the main antagonist of Pokemon Black and White, Ghetsis, who also uses Hydreigon and is the only Trainer to do so.
 * 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 ENW 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 it is the Nega-Wisp Armor. The DS version states it's names as the Nega-Wisp Armor, but in the Wii version, if you turn on the Navigator, it says it is the Egg Nega Wisp.
 * In the Wii version, before the battle starts, if you walk into the help marker to the left of the path, you can actually hear Tails talk, but briefly, and barely, talk in understandable language, saying that he is trapped by Eggman, and is warning Sonic that Eggman is dangerous in the ENW.
 * In the DS version this is not the true final battle of the game the Nega Mother Wisp is fought after it when you collected all the Chaos Emeralds.
