Dragon Ball Z: Broly – The Legendary Super Saiyan

Goku investigates the destruction of the Southern Galaxy while Vegeta is lured to New Planet Vegeta under the promise that he will rule as king. The apparent royal mission hides Paragus's plan to use Broly, the Legendary Super Saiyan, against Vegeta and the others. Once Broly's power breaks free, Goku, Gohan, Trunks, Piccolo, and Vegeta are forced into a desperate battle, and Goku ultimately defeats Broly by drawing on his allies' remaining energy.
