Earth is the main planetary setting during the first three seasons of the 2012 TV series. The planet is home to the human race, but the Kraang Hive Mind intends it to become the new permanent home of the Kraang race. To this end, the Hive Mind has spent millions of years using mutagen to try to manipulate the natural evolution of Earth's life.
In the Season 3 finale, Annihilation Earth!, Part 2, the Triceratons use the Heart of Darkness to destroy the Earth in order to permanently destroy the Kraang Hive Mind's operations on the planet.
