Slizeros

Slizeros is the planet of the Slizers, a race of heavily mechanically-augmented beings who were experimented on by the Kestora against their will over two hundred thousand years ago.

The planet was originally split up into eight different elemental continents, each one drastically terraformed by the Kestora for their own purposes. The Kestora left the planet aeons ago in its chaotic state, considering the world a failed experiment as elemental monsters were accidentally created as a result of tampering with the planet's natural ore with their terraforming machines. Since then, each Slizer race had stuck to their own continents, learning how to fight the elemental monsters to survive.

Recently however, war has broken out worldwide for an unknown reason. All of the different races of Slizers have formed armies, and are fighting to the death against each other and the elemental beings. Many of its forests have been burnt and rivers dried, leaving a majority of the planet in a desolate condition.

Not wishing any outsiders to get involved, an elite silver squad of Slizers called the "Watchmen of Slizeros" have been established in orbit to deter them. An elaborate worldwide shell was also built around the planet, the outside of which displaying an image of how the world looked approximately a hundred thousand years ago.

Recently, the two beings known as Kakamu and Stollercon were intercepted by the Watchmen while they were trying to get to Slizeros on their ship with the purpose of retrieving Kakamu's original datacenter left there by the Kestora. The Watchmen's leader, Sizzler, forbid them entry but Stollercon eventually persuaded him to let them pass. Tired at not letting anyone else in, Sizzler decided that maybe the outer multiverse could in fact help their world, and so hit a box on the side of the shell with an energy disk. This caused a chain reaction, destroying the shell and allowing Kakamu's motorbike to pass.
