Nega Wisp Armour

The Nega Wisp Armour was a booster for the Egg Mobile created by Dr. Ivo "Eggman" Robotnik, used to store large amounts of energy during his search for a power source alternate to the Chaos Emeralds, notably during the Interstellar Amusement Park Incident and the War to Take Back Sonic's World.

Because of its primary purpose as a storage unit, it is designed to connect to other machines such as the Mind Control Cannon and the Mega Eggrobo, but it is also combat-ready individually.

Interstellar Amusement Park Incident
Dr. Eggman's first recorded use of the armour was to contain large amounts of Colour Power harvested from the Wisps and the Mother Wisp. During his attempt to use the Mind Control Cannon, the Armour was badly damaged by Sonic the Hedgehog.

Though much of its function had been removed thanks to the damage sustained during the climax of the Amusement Park Incident, the Armour's main battery functionality remained intact. Retreating to his base on the Lost Hex, the Armour was fitted to the Extractor and the Mega Eggrobo, which was again damaged in a final confrontation with Sonic.

War to Take Back Sonic's World
During the War the Armour was again used to power the Mega Eggrobo, this time with the Phantom Ruby kept inside the Death Egg. During the final battle of the War, the Mega Eggrobo was destroyed, but Dr. Eggman attempted to escape into Null Space with the Armour. Sonic's Army pursued, however, and the Armour was once again put out of commission.
