Dragon Ball Super: Broly is a huge marker for the movie franchise as it officially launches the fan-favorite movie chess Broly into Dragon Balls in serial form. This has been particularly appealing to the fans, as the series series Akira Toriyama handles the character's retcon.
But how has Broly just changed from its original appearance in Dragon Ball Z to be more consistent with Dragon Ball Super ? The character has been retooled from the ground and is now a completely different character than fans are familiar with.
There are tons of changes, both large and small, from his visual review, combat power, origin and relationship to characters like Goku, and new additions such as Cheelai and Lemo from Freeza Force. While this does not explain every little detail of his new character, these are the major retouch changes in Broly's portrayal that will have effects if the character appears again at a different time in the Dragon Ball series.
Read on to find out how Broly has been retconned to his cannon debut in Dragon Ball Super, and of course there are big spoilers for Dragon Ball Super: Broly below!
In Dragon Ball Z Broly and Paragus's relationship was volatile. Broly became such an uncontrollable driven insanity after what happened to him as a child that Paragus had to attach a mind control unit to keep him in check. Because of this, Broly takes the first chance he gets to be completely free of Paragus and kills him. In the new movie their relationship has a little more nuance.
Although Paragus raises Broly to be a warrior on Planet Vampa for revenge on King Vegeta, like the original incarnation, Broly is not a wildly incoherent being. He goes out of control when furious, so Paragus imposes a push on him to suppress him when he gets angry. As Cheelai and Lemo grow closer to him, the bad mouths have Paragus to raise Broly to be a fighter when he doesn't want it.
But Broly has respect for her father invisible in the original. At the end of the day, Broly won't let any other bad mouth raise anyone. There is a complicated connection there, but an emotional connection anyway. 3 by 7 Introduction to Goku, Vegeta
With Broly's new origin, he has no idea who Goku and Vegeta are. Their first meeting in the film is also handled very differently. Instead of traveling to "New Vegeta", Broly and Paragus are brought to Earth's ice continent as part of Freeza's efforts to gather Dragon Balls. Freeza recruits Paragus and Broly for the reason because he not only sees himself jumping over an opportunity to brush Saiyans against each other, so it's all orchestrated by someone other than Paragus.
Although Paragus still orders Broly to fight and the character has the same luggage, there is a consequence that the past does not dictate how the current saiyan trio feel about each other. The fight with Goku and Vegeta thus works out in a different way, as the two types enjoy fighting anothee Saiyan. In the origin, Vegeta was paralyzed by an inferiority complex, and Goku was forced to fight with Broly alone because of Broly's baby groups. But here Broly fights Vegeta first.
Vegeta makes much of the first attack on the character, and he feels himself disappointed with Broly's performance. Goku marks in the end and the two teams up to win overall in the end. But this struggle, while exploding in power, has a less horrible core than the original. They are only three people who test their power against each other until Broly loses control in anger. It's a bit of a tragic, given Broly's emotionally disturbed growth.
One of the major changes for the new Broly is how to activate his Super Saiyan form. There is actually a reason for this being this time. In his original incarnation, Broly has essentially his Super Saiyan power from the jump with an activation of the "Legendary" form as a notch beyond his usual power. But in the new movie when he is not Super Saiyan shaped easily.
When he starts losing to Super Saiyan Blue Goku, it means that Broly has reached the edge of his basic form, even with an extra boost, he does not activate his Oozaru effect while maintaining its humanoid form. Goku became a Super Saiyan with anger over Krillin's death, Freeza k ills Paragus (capitalizes on the complicated relationship mentioned above), and this sends Broly a rage enough to bring him to his Super Saiyan power.
He eventually reaches a "Super Saiyan 2" esque transformation later in the film more akin to his "Legendary" form in the original incarnation, but it also has a new root as it is an extension of Oozaru's power Broly has drained.  Slide 5 by 7 Battle Power
Like his Super Saiyan activation, Broly has a very different base strength than in the original films. Because he is introduced to the series officially after Goku and Vegeta have literally reached Godhoo's level power, his power must also be adjusted to keep the same influence from the original incarnation. Broly in its base form is seen holding up with Vegeta's base form and overwhelmed by Vegeta's Super Saiyan power.
This lasts a moment until Broly's anger brings him to that level and forces Vegeta to turn into Super Saiyan God to stay ahead. In the course of the match, Broly's power to overcome both Goku and Vegeta's SSGs is growing, and in his strongest can match to Super Saiyan Blue. But when Broly goes Super Saiyan, it is all thrown out of the window.
Beating Goku and Vegeta's Super Saiyan Blue-tag efforts and overwhelming Golden Freeza at a later time are forcing his power at this time to melt Goku and Vegeta. Super Saiyan Broly stops with Base and Super Saiyan Gogeta enough, but eventually defeated when Gogeta turns into Super Saiyan Blue. Broly's last fighting power is only defeated when Goku and Vegeta's SSB forms are reported together and enlarged. So it is safe to say that while his power is gradually increasing in the same way in the original incarnation, he ends up pointing far more strongly than the old Broly.
Broly's original look struck so hard by Goku that he explodes. He was a murderer who handled a suitably deadly hand. But it would not fly with the more emphatic version of Broly, which has a far more surprising fate in the new movie.
Because of their struggle, more of a tragic tone and the relationship he established with Cheelai and Lemo who saw him as a confused child, Broly is saved from being defeated by Gogeta with a desire for Dragon Balls. Cheelai and Lemo betray Freeza Force and use Dragon Balls to save Broly and send him back to Planet Vampa. This restores Broly's hygiene, and eventually Cheelai and Lemo run to Planet Vampa to live with him.
Goku comes to Vampa and gives them supplies to let them live in the "conflicting" world and will in turn be able to fight against Broly from time to time. So the biggest change to Broly in general, as it turns out, is that he's no longer seen as just some murderous villains that Goku must overcome. He will probably now be one of their strongest allies as the series advances.
