The '90s Dragon Ball movies infamously all suffer from continuity issues which make it impossible for them to fit into the canon timeline. Compared to their contemporaries, though, Dragon Ball Z: Bojack Unbound slots in rather neatly, with only a few minor continuity hiccups. For this, and a host of other reasons, Bojack Unbound absolutely deserves to be remade as a canon arc in Dragon Ball Super.
Dragon Ball Super: Broly was a triumph, and proved how well remaking the franchise's classic films can work. Compared to the remaining options for this treatment, Bojack is original, far more fun, and filled with wasted story potential to be expanded upon. Broly isn't the only iconic Dragon Ball Z movie villain that deserves to be made canon by Dragon Ball Super, and Bojack & the Galaxy Soldiers should be the next opponent the Z-Warriors face – after Black Frieza, of course.

Every Super Saiyan Vegeta Form in the Dragon Ball Franchise, In Chronological Order
Vegeta’s relationship with Super Saiyan isn’t that different from Goku's, but he's unlocked forms at a unique pace and on a unique path.
As far as Dragon Ball Z movies go, Bojack Unbound is a unique beast. The first half is focused on a lighthearted tournament, it's the only DBZ movie to feature Gohan as the protagonist, and Bojack is the only main villain in any of the '90s Dragon Ball Z movies other than Broly and Dr. Wheelo to not be a rip-off of a character from the anime. Along with being original, DBZ Movie 9 is also exceptionally well-executed by the standards of when it came out. Bojack Unbound's art direction is gorgeous, its score is one of Kikuchi's best in the franchise, Bojack & his Galaxy Soldiers have fantastic designs, the tournament section of the film is a delight, (featuring an especially memorable bout between Future Trunks and Tien Shinhan), and Gohan's power-up against Bojack during the climax is glorious.

Dragon Ball Super Volume 24 Confirms Series is NOT Ending Anytime Soon
Dragon Ball Super Volume 24 brings good news for fans worried about the series' future under Toyotarou as he takes over for the late Akira Toriyama.
The only major flaw with Bojack Unbound is one it shares with every other Dragon Ball Z film that isn't Wrath of the Dragon or Battle of Gods – its story, or lack there of. The split between the opening tournament and the battle against the Galaxy Soldiers makes the film more dynamic than most, but the plot is still paper thin, Bojack and his gang are given nothing in the way of personality or backstory, most of the cast is wasted, and the finale shamelessly rips off the final encounter between Gohan and Cell. Bojack Unbound may be a good movie compared to most other Dragon Ball Z films, but that doesn't mean much.
Apart from the teal-skinned ginger pirates who serve as its villains, Bojack Unbound is best-known for being one of the easiest '90s DBZ films to fit into canon. Besides Wrath of the Dragon, which is set after the events of the series, Bojack Unbound is the only DBZ movie to not directly contradict anything from the anime. Even with Dragon Ball Super creating problems by establishing Future Trunks never went back to the past again after his departure in the Cell Saga, fans have never stopped entertaining the idea of what could be if the film was acknowledged by Dragon Ball Super.
Ideally, the Dragon Ball Super manga will soon return and, when it does, the Black Frieza Saga will finally begin publication. Most speculation from fans is currently about this long-awaited arc, but what comes next should also be considered. Given that Super's strongest story to date has been a remake of Broly - The Legendary Super Saiyan, it may be in the manga's best interest to remake another '90s DBZ film.
Dead Zone and The World's Strongest are too low-stakes, and all the others feature villains that are less-interesting copies of antagonists from the series. There's certainly a camp of fans that would love the canonization of Cooler but, coming off the Black Frieza Saga, it would be exhausting to get such a similar antagonist. The Galaxy Soldiers, composed of Bojack, Zangya, Kogu, Bido, and Bujin, are all essentially blank slates. All fans are ever told or shown about them is that they're evil space pirates who were sealed away by the Kais long ago.

10 Worst-Written Dragon Ball Z Characters, Ranked
Some Dragon Ball Z characters fall so flat in terms of writing that calling them characters at all feels like giving them too much credit.
Dragon Ball Super could take any direction it wanted in fleshing these villains out, giving them their own unique personalities, abilities, goals, and relationships with their peers. Considering that Dragon Ball Super was able to turn Broly, once the face of everything wrong with DBZ, into one of the best characters in the franchise, there's every reason to believe the series is up to the task of giving the Galaxy Soldiers a similar treatment. Given how chaotic the Black Frieza Saga is bound to be, it wouldn't be hard to come up with a new explanation for their sudden appearance.
Whereas their seal on their prison was previously broken by the destruction of King Kai's planet, now it could be explained by whatever havoc Frieza wreaks on Universe 7. In terms of timing, the plot of Bojack Unbound could potentially be mixed into the "End of Z." By the time the Black Frieza Saga comes to an end, the Super manga will have caught up to DBZ's epilogue. With Dragon Ball Z's final episodes, and the opening of BU having such similar settings, it could be a fun surprise if the 28th World Martial Arts Tournament didn't go the same way fans remember it, and if it was interrupted by the Galaxy Soldiers.
The Black Frieza Saga is set to be the most climactic arc in Dragon Ball Super. The franchise's most iconic villain has become powerful enough that he can defeat any of the Z-Warriors with a single attack, Frieza's ultimate goal since the Universe Survival Saga has been to topple the Omni-Kings and conquer the entire multiverse, and the saga is all but guaranteed to be the final battle between Frieza and the Saiyans. Inevitably, Dragon Ball Super will need to find a way to raise the stakes but, immediately following such an intense arc, a breather would be appreciated.
Action-packed and thrilling, but with the stakes limited to the fate of Earth, a remake of Bojack Unbound would let Dragon Ball Super dial things back after the Black Frieza Saga, without losing any momentum. Dragon Ball has effectively implemented breather arcs in the past with Dragon Ball Z's Great Saiyaman Saga, the filler in-between the Future Trunks and Universe Survival Sagas of Dragon Ball Super, and the recent Super Hero Saga. More than just a breather, though, a potential Bojack Saga could transition neatly into the future of the manga.

Is Gohan Beast the Strongest Hero in Dragon Ball Right Now?
Gohan Beast defeated Cell Max in Dragon Ball Super: Super Hero, leaving fans to wonder if he's surpassed Goku, Vegeta, and Broly.
Ever since the Frieza Saga, Dragon Ball has always had to come up with explanations for why new villains are more powerful than the tyrant who was stated to be the strongest being in the universe. This is something that it has done successfully, with the Androids being based off the Z-Warriors' data, Majin Buu having been sealed away, Zamasu having stolen Goku's body, Moro having been imprisoned and having the ability to absorb energy, and Granolah and Gas having cheated to acquire their strength, using the Cerealian Dragon Balls. However, without radically changing the Galaxy Soldiers' core premise as a dangerous band of space pirates, there is no way to justify them being a threat to Goku, Vegeta, or the warrior who defeated them once before, Gohan.
Fortunately, Dragon Ball Super doesn't need to do this. DBS has recently been giving more focus to Goten and Trunks than they've received since the Buu Saga. Combined with Pan's prominence in the Super Hero Saga, and the inevitability of Uub joining the cast during Super's version of the "End of Z," the manga may be signaling that focus will soon be moving towards the younger generation of Z-Warriors. It may be impossible to justify the Galaxy Soldiers as threats to the strongest warriors in the multiverse, but it wouldn't be too much of a stretch if they could initially overwhelm the kids. While not traditionally known for being a fighter, if Bulla were added to the next generation of Z-Warriors as well, the two teams would even both have five members.
Everyone could get their time to shine, and it could all build up to the grand debut of Adult Gotenks, and a battle between him and Full Power Bojack. Fans were skeptical of Dragon Ball Super: Broly when it first came out, but the film wound up being the best product with the "Super" branding. Continuing to remake Dragon Ball Z films may seem silly to some fans, but there's no reason not to draw upon well-known iconography with narrative potential, so long as there's a good story to go with it. If Dragon Ball Super can do for Bojack what it did for Broly, he could very well wind up being one of the franchise's most memorable villains.
