The specific between this Broly and the 1993 version
Forty-one years ago, King Vegeta ruled the Saiyan race with a balance of pride and fear. When he discovered a baby named Broly whose power potential eclipsed that of his own son, Prince Vegeta, he felt threatened. To protect his lineage's legacy, the King exiled the infant to the desolate, monster-infested planet Vampa. Driven by fury, Broly’s father, Paragus, defected and followed his son, vowing to one day use the boy's burgeoning power to exact revenge on the royal bloodline.
As Gogeta prepares a final, lethal blow, Chelye—a kind-hearted soldier who befriended Broly—uses the Dragon Balls to wish him back to the safety of Planet Vampa. The battle ends not with a death, but with a new beginning. Goku later visits Broly on his home planet, bringing supplies and expressing a wish to spar again as friends, famously asking Broly to call him "Kakarot".
In the present day, after the dust of the Tournament of Power has settled, Earth is at peace. However, this tranquility is shattered when Frieza's scouts discover Paragus and Broly on Vampa and recruit them into the Frieza Force. Frieza, seeking a weapon to finally eliminate Goku and Vegeta, lures the Saiyan duo to Earth’s frozen continent under the guise of searching for the Dragon Balls. The Clash of Three Destinies
