Broly is a Saiyan warrior who survived the destruction of Planet Vegeta due to his extraordinary powers. When he was born he had a whopping power level of 10,000 which would continue to dramatically increase as he got older. His hatred towards Goku has fuelled him with rage and is the reason for him unlocking his mighty Legendary Super Saiyan transformation. In the tournament, Broly is seen to be more wild than usual due to the multiple variations of Goku there. This has caused Broly to pass his limits and even achieve the all-powerful Super Saiyan 4 transformation! Broly's intent is to destroy all variations of Goku he sees no matter how many lives will be taken away to achieve it.
