However, his ship gets damaged, causing the two to spend years trapped on the barren world, unaware of the salvation that would one day come from an unlikely ally.

But their sparring is interrupted when the appearance of their old enemy Frieza drives them to search for the last of the wish-granting Dragon Balls on a frozen continent. Once there, Frieza shows off his new allies: Paragus and the now extremely powerful Broly. A legendary battle that shakes the foundation of the world ensues as Gokuu and Vegeta face off against Broly, a warrior without equal whose rage is just waiting to be unleashed.
