Broly

Broly is the main antagonist in the Broly Triple Threat trilogy. He appears to be the latest of the Legendary Super Saiyans who appear every thousand years. Broly's overall character and the general design of his famous Legendary Super Saiyan state was created by Akira Toriyama as well as Takao Koyama. The latter in particular was inspired to create a powerful and menacing Saiyan villain due to watching the transformation sequence of Future Trunks into the Super Saiyan Third Grade in the episode "Trunks Ascends".
