Dragon Ball Z Movie 05: Tobikkiri no Saikyou tai Saikyou (Dub)

Gokuu Son and his friends are out camping when three mysterious enemies ambush them. After a quick fight, a fourth enemy named Cooler joins the fray. Seeking retribution for his younger brother Frieza after he was defeated, Cooler attacks Gokuu; however, the latter manages to escape with Gohan Son and goes into hiding. Unsatisfied and infuriated with the outcome, Cooler and his men begin the hunt to uncover Gokuu's location and kill him to carry out their plans of exacting revenge. After defeating Frieza, Goku returns to Earth and goes on a camping trip with Gohan and Krillin. Everything is normal until Cooler—Friezas brother—sends three henchmen after Goku. A long fight ensues between our heroes and Cooler, in which he transforms into the fourth stage of his evolution and has the edge in the fight ...until Goku transforms into Super Saiyan.
