BiographyBio-Broly's lineage can be traced back several films, to the events of Broly - The Legendary Super Saiyan. After the Legendary Super Saiyan, Broly's defeat on New Planet Vegeta, he makes a frantic escape in his Saiyan Pod as the planet is demolished by Comet Camori. Over time, the pod finally reaches Earth, soon after which Broly collapses from exhaustion and enters a sort of coma, where for seven years, the elements expand around him. Eventually, he is awakened underneath a thick pool of ice by the incessant cries of a nearby Goten, and after escaping this grave, Broly resumes his conquest against the Saiyans who double crossed him, particularly Goten, as Broly's sanity has been breached so heavily since the encounter on New Planet Vegeta that he can hardly tell Goten and his now deceased father apart.
Broly is unsuccessful and is ultimately launched into the Sun by a Family Kamehameha fired by Goten, Gohan and the spirit of Goku, apparently ending the life of the mighty Saiyan. After the Z Fighters leave the vicinity of Natade Village, the people expel the village priest Maloja, whose incompetence before the arrival of the Z Fighters led to the arrangement of a number of per-year human sacrifices.
Now an unemployed vagabond, Maloja wanders about until he discovers Broly's blood-tarnished Saiyan Pod. Realizing what he has found, Maloja collects a sample of this blood and turns it in to wealthy industrialist Lord Jaguar, who prepares to pay the ex-priest handsomely. The blood sample is processed by Dr. Collie's team of scientists and a clone is born. This is where the events of Bio-Broly begin.
When Jaguar "invites" Mr. Satan to his abode, intending to pit the martial artist against other Bio-Warriors in his collection as revenge for his defeat long ago, Android 18, Trunks and Goten follow. It is during a tour at their destination, an island where Jaguar's laboratory fortress resides, that Trunks and Goten discover an incomplete Super Bio-Warrior, uncanny in resemblance to the Legendary Super Saiyan. Before long, Trunks and Goten encounter Maloja, who confirms what he has selfishly done, before escaping to claim his reward. Meanwhile, Jaguar plans to pit Bio-Broly against Mr. Satan.
Trunks and Goten prepare to destroy Bio-Broly before he can be fully replenished, but the clone simply catching sight of Goten is enough to awaken both the Saiyan instincts and the personal vendetta of his source material. Bio-Broly shatters his stasis cell by transforming into a Legendary Super Saiyan, only to be drenched in culture fluid which, upon becoming exposed to air, becomes corrosive. This renders the clone a horribly deformed and slime covered bio-mutant. While Maloja is claiming his reward for supplying Jaguar and Collie with Broly's DNA, the now rampant and extremely dangerous culture fluid oozes upon him, killing him in the midst of an evil-banishing prayer.
Bio-Broly proceeds to rampage about the facility, destroying numerous stasis cells and exposing mounds of corrosive culture fluid to spill throughout the laboratory, some of which begins escaping to the populated island below. While Bio-Broly doesn't have the power of the Saiyan he was cloned from, he still easily defeats Goten, Trunks, Android 18 and Krillin, even with the numerous advantages they gain throughout the encounter. Considering a new plan, which Bio-Broly plays into, Trunks blows open an overhead container of culture fluid, drenching the clone in a corrosive coat which dissolves his body. Goten and Trunks go on to escort civilians away from the island, and with help from Mr. Satan they learn that water is the remedy to outbreaks of the culture fluid, prompting the Z Fighters to fire a number of energy waves into the sea, causing a tidal wave to flood the island and solidify the fluid, neutralizing the hazard. Suddenly, Bio-Broly emerges from the ocean, revitalized and extremely enlarged by his experience with the culture fluid. Within moments however, he too is solidified. With this, Goten, Trunks and Krillin strike the clone with enough energy to shatter him into pieces.
Although he is the bio-engineered clone of the Legendary Super Saiyan, Bio-Broly lacked some of Broly's most distinguishable traits such as his extraordinary strength, speed and stamina. This is especially evident when Krillin was actually able to put up a decent fight against Bio-Broly, whereas the real Broly managed to knock him out in one strike before Krillin could even move in to attack. Despite lacking these features, the clone managed to retain Broly's recklessness, lack of compassion and apparent invulnerability to attacks. Soon after awakening, Bio-Broly's power shattered the culture fluid tank in which he was created, spilling the culture fluid. Once exposed to open air, the culture fluid became a very corrosive fluid that devoured any cellular matter that was not like itself and gained strength and energy as it consumed, allowing the clone to survive in it. The only weakness that this fluid possessed was that it could be solidified by water, including all the genetic material it had absorbed along with it. This glaring weakness ultimately resulted in Bio-Broly's demise.
Techniques and special abilities
- Body manipulation and regeneration – The ability to manipulate one's body and recover from severe bodily damage. Due to being drenched in the culture fluid, Bio-Broly's body becomes malleable, allowing him to recover from slicing attacks like Krillin's Destructo Disk. This malleability is further shown when he attacks Lord Jaguar by stretching his neck and twisting his head 180 degrees in order to use his eye laser to blast Jaguar, who had been standing on a catwalk behind him and shouting at him to stop his rampage.
- Flight – The ability to fly with the use of ki.
- Double Eraser Cannon – A more powerful version of the Eraser Cannon, which involves Bio-Broly firing two at once. He used this attack against Goten and Trunks simultaneously.
- Eraser Cannon – A powerful green energy sphere and the signature technique of the original Broly.
- Eye Laser – Whereas all of Broly's blasts having a green coloration, Bio-Broly's eye laser is distinctly red in color. It is used twice in the film and is one of three abilities that he has access to that the original Broly doesn't, with the other two being the mouth energy wave and regeneration.
- Mouth Energy Wave – A fluctuating beam of green energy fired from his mouth.
Legendary Super Saiyan
Legendary Super Saiyan As Broly's clone, Bio-Broly also has access to his source material's Legendary Super Saiyan transformation. After awakening for a brief moment and catching a glimpse of both Goten and Trunks, Bio-Broly immediately ascends to this form and proceeds to use it for the rest of the movie.
- Japanese Dub: Bin Shimada
- Funimation Dub: Vic Mignogna
- Bio-Broly is the first of three consecutive villains in film who have very few speaking lines, besides grunts and other agitated sounds (although in his first form, Janemba says his name a number of times in Fusion Reborn).
- In the Japanese dub, Bio-Broly only says one word in the whole film: Kakarot.
- Trunks' method of defeating Bio-Broly, albeit temporarily, by having him to be consumed by the culture fluid is similar to Gohan's attempts to have the original Broly swallowed by a river of lava in Dragon Ball Z: Broly - Second Coming.
- Bio-Broly is never referred to as such in the film, as all characters in the movie merely call him "Broly".
- This is the only movie villain that Goku does not help in defeating. In every movie that he's alive, he obviously helps fight the villain and in Dragon Ball Z: Bojack Unbound and Second Coming, he somehow comes out of Other World to help his son(s) for a brief moment (the former by "breaking the rules", and the latter via Shenron).
