Hyper-go-on is a very strong energy that serves as the life force of Wisps, and can be utilized for several other purposes. It is able to grant the use of Color Powers, possess machinery, convert Nega-Wisps back to their normal selves, and even teleport entire planets.
By harnessing the Hyper-go-on energy from a Wisp, users are able to use its Color Power, transforming into a different form that grants special abilities such as new attacks or environmental advantages. The appearance of the transformation and the abilities obtained depends on the type of Wisp and its Hyper-go-on energy.
In Sonic Colors, Dr. Eggman's scheme to conquer Sonic's world involved stealing the Hyper-go-on energy obtained from Wisps and converting it to negative energy to power a massive Mind Control Ray. To accomplish this, Eggman rounded up the planets inhabited by Wisps and connected them to Dr. Eggman's Incredible Interstellar Amusement Park. Eggman and his forces then began capturing the local Wisps and bringing them to Asteroid Coaster where the Hyper-go-on was drained from the Wisps and converted into a negative energy, a process of which turned the unfortunate Wisps into Nega-Wisps. The negative Hyper-go-on was then stored inside giant tanks in the mind control cannon in Tropical Resort. During a battle between Sonic and the Rotatatron however, the Hyper-go-ons' tanks were punctured by one of Rotatatron's arms. As such, when Eggman tried firing the mind control cannon, the cannon malfunctioned and backfired. This triggered a chain reaction that sent the accumulated negative Hyper-go-on energy flying in every direction. One burst of energy impacted the moon, coating it in a purple smoke. The uncontrolled energy then began to form a massive black hole that began consuming Dr. Eggman's Incredible Interstellar Amusement Park. Fortunately, the Wisps saved by Sonic used their Hyper-go-on to not only save Sonic from the black hole, but also neutralize the black hole, restore the Nega-Wisps to normal, and return their planets to their rightful places in the universe.
In Sonic Colors, whenever Eggman robs Wisps of their Hyper-go-on energy, they turn into Nega-Wisps. Despite this, when Sonic uses the Hyper-go-on energy to transform into a Color Power, the Wisps appear to be fine. This could be because Eggman completely drains the Wisps, whereas Sonic only uses some of their power.
