Dragon Ball Z: Chikyuu Marugoto Choukessen

EP1

The Earth's destruction lies dormant within a single, solitary seed. Brought forth from the darkest reaches of space, the Tree of Might has been sown with the vilest of intentions, for once it takes root nothing else can survive. A plant designed to drain the energy of a planet, it steals the very essence of life only to blossom in death and desolation. Unable to fell this mighty threat, Goku and the Z Warriors must instead confront the harbinger of the evil, a Saiyan bearing an uncanny resemblance to our hero - Turles. This new enemy kidnaps Gohan and sets the son against the father, a tragedy which only delays the inevitable fight. As Goku finally faces off against his deplorable double, Turles turns to the thieving tree?
