Broly (DBZ)

Broly is one of the antagonists from the Dragon Ball game series. He was born with a power greater than most elite adult Saiyans, and is mentally unsettled as an adult due to the crying of the infant Goku in the incubator next to him when they were born, traumatic events during his childhood (including nearly being executed as well as Frieza's genocide) and also in part due to his extreme power.

He eventually becomes the "Legendary Super Saiyan" told of in legends, with his destructive tendencies only being quelled by a special controlling device created by scientists for his father, Paragus. After Paragus lures Vegeta, Goku, and their companions to another planet, Broly recalls Goku and goes into a rage, destroying the control device and becoming the unstoppable Legendary Super Saiyan.

He effortlessly pummels Super Saiyan Goku, Vegeta, Gohan, and Trunks as well as Piccolo, before killing his father. He is eventually defeated by Goku, but somehow manages to make his way into an escape pod. He lands on Earth and goes into a frozen state until the crying of Goku's son Goten awakens him. He is killed by Goku, Gohan and Goten by their combined Kamehameha attack after being blasted through the sun.

History
Broly is the Legendary Super Saiyan and one of the most dangerous fighters in the universe. Born with a power level of a whopping 10,000, Broly was condemned to be executed alongside his father Paragus by King Vegeta out of jealousy. However, he survived Planet Vegeta's destruction at the hands of Frieza and proceeded to cause chaos everywhere he went in his hunt for Kakarot, the Saiyan whose constant crying in the nursery drove him to insanity (and most likely caused sleep deprivation).

He would be defeated on three occasions: first by Goku with help from Piccolo, Trunks, Gohan, and Vegeta, then by Goku and his sons, Gohan and Goten, and finally, by Goten and Trunks when he was resurrected as "Bio-Broly," a clone of the original Broly who was in the Underworld at the time, wreaking havoc.
