Arus is set to host the Space Olympics as they are thriving thanks to Voltron. Zarkon and Lotor are too jealous to participate, but plan to take advantage of Haggar's offer to bring down Arus. They place a small robot in the earth-mover that the Voltron Force is using to construct the facilities, planning to use it to destroy the buildings and then the planet. The children helping them are taken hostage within the machine. The Voltron Force are forced to stop the mechanical rampage while keeping themselves and their friends alive as well.
