Grooves or Groove Beings are entities that contain the energy of evolution or "Groove Power". Groove Power can be within life forms with helical DNA or even in galaxies in a Groove. Groove Power amplifies a Groove person's potential infinitely and causes them to be blindly driven towards their goals. Grooves are identified by their complete drive to continuously fight and evolve regardless of the circumstances surrounding their evolution.

Other races recognized and feared the limitless potential of Groove Power and formed a group against them called the Anti-Grooves. The Anti-Grooves had fought a war with the Grooves and won. The Grooves were forced to flee back to their homelands - one of which was Earth. After the Anti-Grooves conquered the galaxy, they installed Groove life-form Annihilation Devices on any world where they detected a Groove life-form signature. When the above ground life form population exceeded a set limit, the device then activated and destroyed whatever Groove life-form present on the planet. In the case of the Earth, the Annihilation Device was its moon. When the Earth's human population reached the set limit (1 million), the moon would start on a collision course straight into the Earth and destroy the human race, who were at the focal point and spearhead of this Groove progression.
