The Black Hole

The Black Hole is located at the centre of the universe and is the birthplace of all Hedgehogs. It also serves as a gateway to other universes and dimensions.

History
The Black Hole, and thus the entire universe, was created by Nennreon. In order to protect The Black Hole and the universe, Nennreon gave birth to five Hedgehogs: Shortly after, Nennreon left for another universe through The Black Hole and left his 5 children to do as they please.
 * One, a hedgehog with the ability to wield the Red, Blue, Yellow, and Purple powers.
 * Neo, a hedgehog with total mastery of the Purple power.
 * Eon, a hedgehog with total mastery of the Yellow power.
 * Neon, a hedgehog with mastery of the Red and Blue powers, and the only Hedgehog other than Nennreon to be able to use the White power.
 * None, a corrupted hedgehog with total control over the Black power which he can convert into deadly Death Black Energy at will.

After 100 years had passed, Nennreon sent Colonel Sanders from another universe through The Black Hole to feed Neon some KFC in order to turn Neon into a "true gentleman". As thanks for the KFC, Neon used the White power to give Sanders Red and Blue power, turning him into Coloneon Sanders.
