Paragus

In Dragon Ball Z: Broly - The Legendary Super Saiyan, Paragus appears before Vegeta posing as a loyal subject, claiming to have built a new Saiyan homeworld called New Planet Vegeta. He invites Vegeta to rule over this new kingdom, but his true intention is to lure Vegeta into a trap where Broly will destroy him.

Paragus harbors a vendetta against King Vegeta, who ordered infant Broly to be executed when his power level registered at an extraordinarily dangerous level. Both Paragus and Broly survived the assassination attempt and the subsequent destruction of Planet Vegeta, but the experience left Paragus obsessed with vengeance. He uses a special headband device to suppress Broly's personality and control his actions.

When Broly's conditioning breaks down in Goku's presence, Paragus loses control of his son entirely. In a desperate attempt to survive the destruction of New Planet Vegeta by an incoming comet, Paragus tries to escape in a space pod. Broly catches his father and crushes the pod with him inside, killing Paragus before hurling the wreckage into the comet. His death underscores the tragic futility of trying to weaponize a force of nature like the Legendary Super Saiyan.
