The Transmetal driver, referred to by the Vok as a Datasphere, is a small spherical device that Megatron obtained while on prehistoric Earth (exactly how he came it across it is unknown, though one therory is that he discovered it amongst the wreckage of either the planet buster, the stone trap, or the alien space ship), where many other traces of the Vok were found. It served as a receptacle of scanned data the Vok accumulated from one of the Beast Warriors (presumably Optimus Primal), but according to an analysis by the Maximals' computer it was altered by Megatron. The driver was a necessary part of a transformation into a Transmetal 2.
