The Nega-Wisp Armor (エッグネガウィスプ Eggunegau~isupu?, lit. "Egg Nega Wisp") is the final boss of the Wii version of Sonic Colors and the penultimate boss of the Nintendo DS version of the same game. The Nega-Wisp Armor is a giant robot piloted by Dr. Eggman, who uses the powers of the Wisps and can combine them at his will. Because the Nega-Wisp Armor drains Hyper-go-on quickly like the Mind Control Ray, Dr. Eggman needs to harvest Wisps constantly throughout the battle.
The Nega-Wisp Armor 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 purple spikes, small stubby legs around the front and sides, a long tail out the back, and two large tentacles with sharp pincers on each end that contain a pair of purple eyes making them look more like mouths which it uses to fire lasers and cubes from and also to harvest nearby Wisps with a vacuum inside the mouth which sucks them into large tanks located on its back. The tanks change color depending whatever action it is performing. The cockpit is located at the front just above its eyes with a red arrow (resembling a nose) in front pointing down towards its mouth.
The Nega-Wisp Armor in the DS version looks similar to its Wii version counterpart with a few differences. Instead of having two tentacles for arms, it has one tentacle for a tail. The Nega-Wisp Armor can detach the pincer on the tail use it to perform darker versions of the color powers. It also has a cannon hidden in the mouth of the main body that it uses for specific Wisp powers. For example, the cannon fires missiles at Sonic when using the Violet Void power. The cannon can also fire a large blast when it loses all of its Wisp powers.
The battle takes place on a seemingly endless path in 3D with three lanes for the player to Quick Step between. In the beginning, there are ten Rings which can be picked up to withstand the Nega-Wisp Armor's attacks. When the battle begins, it prepares to attack by using a vacuum to draw in nearby Wisps from the background. The Nega-Wisp Armor's attacks are based on the following Color Powers (one or several of these attacks may be used depending on how many times this boss has been hit):
- Cube: The Nega-Wisp Armor fires several energy shots into the air which land on the ground as cube-shaped energy containers which will damage the player on contact. The player must use the Quick Step to avoid running into them. In later stages of the fight, the Nega-Wisp Armor will fire longer arrays of cube containers.
- Spikes: The Nega-Wisp Armor fires two waves of purple spiked energy balls down all three lanes on the arena. These balls will roll towards the player and damage them on contact. The player can avoid them by jumping over them. In the heat of battle, the Nega-Wisp Armor will fire up to three waves of spiked balls.
- Laser: The Nega-Wisp Armor fires a purple laser from one of its tentacles which sweeps across the arena's path a few times. The player can avoid it by jumping over the laser. In the later stage, the Nega-Wisp Armor will perform more shots of this attack with each succeeding attack being faster than the previous.
In the later stages of the fight, the Nega-Wisp Armor will appear behind the player (the camera will shift its perspective in response to this) and attack from there. Sometimes, the Nega-Wisp Armor will combine two of the following attacks together:
- Cube and Spikes: The Nega-Wisp Armor deploys the aforementioned cube containers but will also drop the aforementioned spiked balls which will roll towards the player. Each time the spiked balls hits a cube, it will change lane.
- Cube and Laser: The Nega-Wisp Armor deploys the aforementioned cube containers in a pattern. After a delay, the aforementioned laser attack is then launched, which will be refracted from one cube into another.
After each attack interval, the Nega-Wisp Armor will be left vulnerable; the player has here a chance to skip across its tentacles with the Homing Attack and finally strike Eggman in the cockpit. The player will then gain energy for the Boost Gauge, which can be used to follow up with a Boost to attack the Nega-Wisp Armor again. Attacking the Nega-Wisp Armor will also cause it to drop Rings. Each time the Nega-Wisp Armor is hit a certain number of times, a Wisp will appear and float alongside Sonic. Afterwards, the Nega-Wisp Armor will repeat its attack patterns.
When the Nega-Wisp Armor is on the brink of defeat, the player must activate the combined the Color Powers of all the Wisps Sonic has saved to perform the Final Color Blaster to finish it off.
In the DS version, it uses Burst, Rocket, Drill, Laser and Void Color Powers to attack. When using Burst it gets close to the platform, charges the attack and shoots a purple flame across the screen. When using Rocket it gets under the platform and shoots five rockets; the fifth one Sonic has to boost into. When using Drill it gets into the middle of the screen and whips the drill around the platform, and falls to the platform giving Sonic a chance to boost into it. The Laser power lets its claw shoot a laser repeatedly, before charging up a final, more powerful laser, giving Sonic a chance to boost into it to let its claw shoot the Nega-Wisp Armor itself. When using Void, its claw will go to the left off the platform and begins to suck Sonic towards it and the Nega Wisp Armor will go to the right of the screen shooting missiles at Sonic. He needs to boost into it to stop the attack.
When hit enough times, the Nega-Wisp Armor is on the brink of defeat. The player must then activate the combined the Color Powers of all the Wisps he has saved to perform a final, combination attack called the Final Color Blaster to finish off the Nega-Wisp Armor.

- Unlike the Wii Version, in the DS version, when Sonic saves a colored Wisp from the Nega-Wisp Armor, it loses the power of the colored Wisp; and when all the Wisps are saved, Eggman uses a suicidal assault by firing a black hole cannon that was hidden in the robot's mouth.
- Unlike the Wii version, the DS version's Nega-Wisp Armor has a tail instead of arms.
- During the Wii battle, the announcer sounds perfectly normal, but in the DS version, the announcer gets an eerie, distorted voice. The latter is probably done to imply the "Nega" aspect of the Wisps. Also, despite the Nega Wisp Armor using Nega Wisps, the announcer does not add Nega before the Wisp power, like "Nega Laser!"
- Unlike most other final bosses, this boss has an extra stage after it.
- The Cyan Laser is the only Color Power that the Nega-Wisp Armor uses in both versions of the game.
- In the DS version, the Cyan Laser attack bounces off walls similar to how Sonic uses it.
- When the Nega-Wisp Armor recharges, it seems to suck up only White Wisps.
- In the Wii version, before the battle starts, if you run into the help marker to the left of the path, you can actually hear Tails briefly, and barely, talk in understandable language, warning Sonic that the Nega-Wisp Armor is very powerful and that Eggman is dangerous in the Nega-Wisp Armor.
- In the DS version this is not the true final battle of the game; Mother Wisp is fought afterwards, when Sonic has collected all the Chaos Emeralds.
- In the Wii version, Eggman presses a button at the same time as Sonic uses a Homing Attack on the Nega-Wisp Armor's head. This makes it seem as if the button cues Sonic's Homing Attack.
- In the Wii version, the music is split into two phases but the battle is not. Phase 2 begins after the Pink Wisp has been collected.
- Conversely, in the DS version, the second phase of the music just barely makes an appearance, only showing up when Sonic is charging up the Final Color Blaster.
- Nega-Wisp Armor's arms resemble Sonic's Purple Frenzy form.
- This boss shares a lot of similarities with the Eggrobo from Sonic Lost World.
- The third phase of the Death Egg Robot from Sonic Forces bears a strong resemblance to the Nega-Wisp Armor.
- Green Hover and Purple Frenzy are the only Color Powers not used in the fight.
