Dragon Ball Z Movie 03: Chikyuu Marugoto Choukessen

A strange probe crashes near the forest where Gohan, Kuririn, Bulma, and Oolong are camping, sparking a fire that the Dragon Balls are used to repair. Days later, the real purpose of the probe is revealed when alien warriors plant the Tree of Might, a colossal organism that drains the planet's life to produce fruit capable of granting tremendous power.

Gokuu and his friends race to destroy the tree before Earth is left barren, only to face Turles and his powerful crew. When Turles eats the tree's fruit and turns its stolen energy into overwhelming strength, Gokuu must fight an enemy who looks disturbingly familiar while the planet itself withers around them.
