Eyeballz are peaceful creatures living on planet earth. They've been preyed on by the Slimeballz since the dawn of time, sightless creatures who want to steal the sight from the Eyeballz.
Milennia ago, Oculus created the power crystalz and cast them to earth on a meteor. When the Eyeballz interacted with the crystalz, they became Superballz. The Superballz fought for the Eyeballz and weakened them until Oculus was able to cast them to the nether regions of the universe.
The Slimeballz have since regained their strength under General Molemax and are preparing for war.
