My Video Q

Broly was born in 737 Age, during the period of intense turmoil between Frieza and the Saiyans. At birth, his most curious feature was his inordinate power level of 10,000. This anomaly meant that by birth, Broly's power had already been close to that of Bardock and King Vegeta at the time of their deaths (which coincidentally happens during the afternoon of Broly's birth). In the Saiyan delivery room where he rests afterward, Broly is grieved by the constant disruptions of his literal 'crybaby' neighbor, Kakarot (later rechristened Goku). These neighboring babies are the butt of a joke by presiding doctors, who rave over Broly's power level but criticize his reaction to Kakarot's crying, while also criticizing Kakarot's then-measly power level of two while also stating that though he has a low power level, he has the spirit of a Saiyan. Broly's exceptional gifts brand him as the first Legendary Super Saiyan in approximately 1000 years.

King Vegeta fears the threat the boy poses to his empire, and so he
gives the order for the infant's execution. Broly's father, Paragus, begs the king to spare the child's life, attesting that his son could be an extreme asset to King Vegeta and his prince. King Vegeta is quick to point out that while this is true, the same is true that Broly could use his ever-increasing strength to overthrow the Saiyan royal family. King Vegeta closes the argument by sentencing Paragus to death for dis-allegiance, shooting him with an energy wave, and throwing him to the garbage holding area within a space ship along with Broly.
From the beginning of his life, Broly was plagued by threatening environments, which evidently have had a lasting impression on his character. The day he was born, he was noticeably disturbed by Goku's incessant cries in the adjoining cradle. His troubles would only double with his attempted execution by order of King Vegeta, when Broly is stabbed in the abdomen with a dagger. Having survived this execution likely thanks to his amazing power level, Broly faces yet another threat that day, when Frieza's Supernova destroys Planet Vegeta after commencing his genocide of the Saiyan race, vanquishing all but eight Saiyans (4 in the original manga and anime, 8 with movies and specials). As his world is decimated, Broly shields himself and his father using an Energy Shield, which allows both Broly and Paragus to survive without air; this is the first time Broly demonstrates what just his infantile power is capable of. The attempted execution also increases the strength of both father and son, due to the Saiyan ability to greatly increase their strength after recovering from near-death experiences. Broly continues to hold a subconscious hatred against Goku throughout the rest of his life.
As Broly develops, it becomes clear to Paragus that King Vegeta was not unjustified in doubting his allegiance
in the long-term. As astonishing as his son's power level becomes in such short time (especially considering the lifespan of the typical Saiyan), his disturbance and emotional instability are always one step ahead. While Saiyans generally enjoy the thrill of battle (which Frieza had somewhat rewarded his followers with, by tasking them with enslaving numerous planets), Broly was exhilarated by physically destroying whole planets at a time. Paragus eventually loses whatever influence he might have had over his son when Broly is in his teenage years, as illustrated by a bloody sequence in Broly - The Legendary Super Saiyan, in which Broly punches Paragus in the face and blinds him in the left eye. Fearing for his own safety while considering the possibilities of having Broly's power at his back, Paragus has Krang, a scientist who served Paragus, craft a ring to be used as a special control device to keep Broly under restraint. Paragus narrowly manages to survive adorning Broly with the ring, Broly's calmness vanishing as soon as he notices the ring that Paragus tries to place on his forehead. But after successfully doing so he soon launches a plan to rekindle Saiyan dominance, where he plots to use Earth as a base of operations, and take revenge on the eldest son of King Vegeta by luring him to a planet doomed to be destroyed by a giant comet. During this time, he also used Broly to destroy the remaining planets in the South Galaxy, such being the main cause of the realization of disturbance in the


universe from King Kai, which caused him to contact Goku and inform him of the Super Saiyan threat.
