The Void

The Void is the home Universe of Albert and Trebla.

Origin
The earliest known use of "The Void" was in a Kung-Fu Panda Talking Game. Albert, about to be apprehended by Po, escaped into The Void to get away.

As a Universal Hub
The Void is the only known Universal Hub, meaning that from within The Void, a person can travel to any Universe in existance. This is the method Albert and Trebla use to get around quickly. As well as being able to travel between Universes, The Void also allows Dimensional Travel.

Entering The Void
As The Void is the only Universal Hub in existance, entering it is highly sought after. However, getting to The Void can prove to be exceedingly difficult. The only known people to have the ability to enter The Void are Albert and Trebla, and the only known people other than those two to have been there are Kirby, and Toon Link, who later proved to be Rainbow.

The Battle for the Land of Trophies
One particular event that occured in The Void was the Battle for the Land of Trophies. Albert and Trebla were fighting for claim of the Land of Trophies, and whoever won would rule the land permanently. The battle lasted approximately Two and a Half hours, with both Albert and Trebla having Ninety-Nine lives. The battle came to be so intense that it opened up a portal, where Toon Link and Kirby both sneaked into The Void to spectate the fight. During the first half, Albert was winning, but the influences of Toon Link and Kirby gave Trebla the upper hand. After a few more long hours of fighting, Trebla finally won the battle. However, as Toon Link was still alive by then, he revealed himself to be Rainbow, and started attacking Trebla. The attempt was futile, though, as in The Void, both Albert and Trebla's strengths are multiplied by 300%. Rainbow was easily defeated, and the Land of Trophies was taken over by Trebla.
