The Tree of Might

A seed of the Tree of Might has been planted on Earth by a group of space pirates. Once rooted, the Tree of Might will devour all life energy, leaving the land a deserted wasteland where no living thing can survive. Goku and friends try to destroy the tree, but their power is not enough.

Suddenly, they are attacked by the evil space pirates, and Gohan is captured by Turles, the evil leader of the group and a Saiyan! Turles powers up by eating a piece of fruit from the tree and begins a ferocious assault on Goku. Will Goku be able to rescue his son, defeat Turles, and save Earth?!
