Dragon Ball Super is Stealing the Original Broly Movie's Plot
Warning: contains spoilers for Dragon Ball Super chapter 71!
A major plotline in Dragon Ball Super's latest arc comes directly from a moment central to the original, non-canonized Dragon Ball Z: Broly - The Legendary Super Saiyan, as the Granolah the Survivor saga revives plot details that have been missing from the series ever since.
Before the franchise's relaunch with Dragon Ball Super, the Dragon Ball Z era was expanded by a raft of movies, but all of these films were notoriously non-canon. This upset some fans who wanted to see certain villains expanded upon in the regular-running series, though many changed their minds once it emerged that some of the movies (and their villains) were exceptionally bad. Broly - The Legendary Super Saiyan stood above the rest of the pack in terms of quality, and has been a fan favorite ever since its release in the early '90s. That's why fans rejoiced when Dragon Ball Super announced that Broly's story would not only be revamped, but canonized. The end result, Dragon Ball Super: Broly is seen by many as superior to its predecessor, and even the show itself, but even then, some aspects of the original film did not transfer over.
In the original Broly film, a mysterious alien spaceship lands on Earth and a Saiyan named Paragus introduces himself to Vegeta, bowing and referring to him as "King." Paragus tells the Saiyan prince that he created a new planet so Vegeta could assume the throne as ruler. While Vegeta is unsure about ruling the newly christened New Vegeta, he agrees to help Paragus upon learning the Legendary Super Saiyan is running rampant in his new kingdom. The Saiyan prince has no reason not to trust Paragus, but it soon becomes apparent that his invitation is a trap. In fact, Paragus hopes to avenge King Vegeta's attempted to murder his newborn son, Broly, the actual Legendary Super Saiyan.
In Dragon Ball Super's Granolah the Survivor arc, the titular villain and sole survivor of the Cerealian race seeks revenge on the Saiyans for annihilating his people while under the employment of Frieza. Upon learning about Goku and Vegeta, Granolah hatches a plot to lure the Saiyans to him so he can destroy them with the help of the Heeters intel group. The Heeters send two of their minions to Earth who request to employ the services of Vegeta and Goku to help them defeat an unnamed but powerful enemy. The two Saiyan warriors quickly agree to help and leave on the alien spacecraft, unwittingly playing right into Granolah's hands.
This particular trope has been nonexistent in the official Dragon Ball canon until now, as most villains come directly to Earth with plans of either annihilating or enslaving the world - notable in a franchise increasingly famous for repeating ideas. The main difference, however, is that Dragon Ball Super's rendition of this particular plotline strips the mystery from the original Broly movie. Long before the arrival of Heeters' goons, readers had already been introduced to Granolah and knew of his plan to lure the Saiyans to him. Fans were aware of no such thing when watching the original Broly movie for the first time. For all they knew, Paragus had been telling the truth, just like Vegeta believed. This only made the appearance of Broly more of an enigma before he was finally revealed to be the Legendary Super Saiyan.
While this twist is absent in the Granolah the Survivor saga, the plot of aliens luring Goku and Vegeta into danger on a hostile planet by asking for their help with a staggering threat is one only really seen before in Dragon Ball Z: Broly - The Legendary Super Saiyan, allowing fans to experience this particularly enjoyable plot finally in continuity thanks to Dragon Ball Super.
