Born on Planet Vegeta in Age 732 as a Saiyan mutant, Broly possessed a staggering birth power level of 10,000, surpassing even Prince Vegeta. Fearing his potential threat, King Vegeta exiled the infant to the desolate planet Vampa. Broly's father, Paragus, followed him into exile, leading to their stranding on Vampa. Paragus raised Broly under harsh conditions, employing a shock collar to suppress his son's volatile outbursts. During their isolation, Broly formed a profound bond with a giant creature named "Ba"; he later wore Ba's severed ear as a memento after Paragus damaged their relationship. Surviving over four decades on Vampa, Broly honed exceptional combat prowess through relentless battles against the planet's native fauna. His prolonged isolation resulted in limited social skills and fostered a reserved, gentle nature. Broly exhibited atypical Saiyan traits: unwavering loyalty to his abusive father, deep compassion, and a reluctance for unnecessary violence. However, intense emotions or extended combat could trigger uncontrollable rage, plunging him into the berserk "Wrath State" where his power surged catastrophically at the cost of his rationality. In Age 780, Frieza Force members Cheelai and Lemo discovered Broly and Paragus. Recruited into the Frieza Force, Broly formed genuine friendships, especially with Cheelai. She later destroyed the shock collar remote, freeing him from Paragus's control. Broly's naïveté about society was evident in his fascination with basic comforts like ration bars and clean water. Orchestrated by Frieza and Paragus, a mission to Earth pitted Broly against Vegeta and Goku. His adaptive fighting style allowed him to grow rapidly stronger mid-battle, overwhelming both Saiyans even in their Super Saiyan Blue forms. Frieza engineered Paragus's death, triggering Broly's transformation into a Super Saiyan. This amplified his power but shattered his sanity, turning him into a mindless force attacking indiscriminately. To counter this threat, Goku and Vegeta fused into Gogeta. Broly escalated further to his "Super Saiyan Full Power" form. Before Gogeta could deliver a fatal blow, Cheelai and Lemo used Earth's Dragon Balls to wish Broly safely back to Vampa. Post-battle, Broly reverted to his gentle self, expressing remorse for his actions. Goku later visited Vampa, bringing supplies and offering training to help Broly control his power, establishing a friendly rivalry and mentorship. Broly subsequently relocated to Planet Beerus, training under Whis alongside Goku and Vegeta. He focused on emotional regulation during combat, striving to channel his immense power without succumbing to rage. Physically, Broly is distinguished by his towering stature, olive skin, scars (including one across his left cheek), and spiked black hair. His attire evolved from Frieza Force armor to a simple black long-sleeved shirt and pants, reflecting his preference for non-restrictive clothing.
