With twelve episodes already out in David Production's adaptation JoJo's Bizarre Adventure: Stone Ocean, fans have seen a lot of Jolyne's misadventures with much more to come. Some of the best fights, shocking events, and unforeseen revelations have yet to be animated.
Although all the anime adaptations of JoJo's so far have been fairly faithful, there have been a few changes made that were for the better. There are certainly some ways that the manga could change in its adaptation and David Production shouldn't shy away from making the anime the best show it can be.
10 Make Dragon's Dream Less Helpful
Among the Stands in JoJo's Bizarre Adventure, most are exciting, flashy, and their power is immediately apparent. In the Punishment Ward arc, there are Stands that seem to be bad luck for their users. Kenzou's Stand, Dragon's Dream, is a dragon-shaped compass Stand that uses Feng Shui to point out lucky locations for successful attacks. However, the Stand is sentient and tells Kenzou's opponents exactly how it works. When F.F. defeats Kenzou, it's partially thanks to his own Stand, which seems a bit anticlimactic.
9 Survivor Needs A Visual Upgrade
Another Stand from the Punishment Ward arc, Survivor is essentially comprised of small electrical impulses that travel along the ground and into human's limbic systems. This stimulates their rage and consumes them with pure anger and fighting spirit, prompting them to lash out and fight anyone around them to the death. In the manga, Survivor looks a lot like little living noodle circles and less like electrical impulses. Some visual effects could go a long way towards making Survivor cooler.
8 Sky High Should Be Less Cryptozoology & More Stand Phenomenon
When Stone Ocean brings up DIO's children, audiences are introduced to DIO's son Rikiel, who controls a Stand called Sky High. This Stand can control strange, rod-shaped organisms that are incredibly difficult to see, and Rikiel uses them to affect his enemies in cruel ways. He can cause eyelids to bleed, skin to bloat, and other strange symptoms. Accepting that these cryptids simply exist in the world of JoJo's challenges audience immersion, and the Stand's power is just to command them. Having Rikiel's Stand be responsible for their creation is a better explanation.
7 Don't Adapt The Weird "Jolyne" Jotaro/Jolyne Wound Scene
Due to Whitesnake's power stealing his Memory DISC, Jotaro Kujo spends much of Stone Ocean in a catatonic state. In a one-off chapter between arcs, he's shown in the care of the Speedwagon Foundation, where he smashes an IV and sustains a cut on his arm that spells out Jolyne.
Jolyne, who's currently very far away from Jotaro, suddenly sustains the same wound before it heals. This scene doesn't make a lot of sense with any of their powers or the Joestar heritage's connections, so it's better left out.
6 You Can't Use Mickey Mouse, Araki
Another of DIO's sons wields the utterly bizarre Stand Bohemian Rhapsody, which brings characters from fiction to life and draws its victims into fighting characters that they identify with. This occurs as Anasui and Weather Report are driving past Disneyland when an upset Anasui discovers that there's no Mickey Mouse on signs or guidebooks. Using the fairytale characters from later in the arc is fine, but I can't imagine Netflix or DavidPro want to mess with the House of Mouse on this one.
5 Yo-Yo Ma Shouldn't Be Defeated By A Frog's Brain
This defeat just too bizarre, even by JoJo's standards. Yo-Yo Ma is an invincible, sentient Stand that's incapable of taking real damage and sent to kill Jolyne Cujoh with its acid spit. However, Anasui manages to put a stop to it by implanting a poor, innocent frog into the Stand's head and connecting its brain to the Stand's "target sensor." This confuses and slows the Stand down long enough for F.F. to kill its user. Instead of using a workaround like a frog brain, it'd be better to have F.F. kill D an G faster in the anime.
4 Make The Green Baby Arc A Little Less Strange
In Enrico Pucci's quest to achieve Heaven, he instructs Sports Maxx to use his zombie-creating power on a bone from DIO. This causes the bone to display strange powers, giving it an infectious quality that turns anyone who touches it into a plant. Thirty-six prisoners are transformed into plants and their souls are somehow used to create the Green Baby from DIO's bone. Appearing as a dark green infant with the Joestar birthmark, the baby fuses with Pucci and brings out the priest's second Stand, C-Moon. None of this makes any sense and the manga doesn't provide answers.
3 Figure Out A More Logical Way To Beat Jail House Lock
When Jolyne is trying to escape Green Dolphin Street Prison, Emporio informs her that, thanks to Stand user Miu Miu and her ability Jail House Lock, that's all but impossible. Jail House Lock prevents the creation of new memories after three, meaning a fourth thing learned after her ability affects you makes you forget the first piece of new information.
Eventually, this leads to a complete breakdown of logical thinking. Jolyne defeats Miu Miu in the end by using Stone Free to print out a picture of Miu Miu's face from Emporio's memory, but a trick with bullets and mirrors earlier is much better.
2 Heavy Weather Needs A Better Explanation
Anyone who reads or watches JoJo's knows that, sometimes, Stand ability explanation just isn't forthcoming and sometimes acceptance is the only way. Heavy Weather, though, is a strange ability that Weather Report creates when his Memory DISC is restored. Strange Weather causes the sun's rays to make people and animals think they're turning into snails before they physically start turning into snails since they believe it so deeply. It's never really explained outside of illusion and susceptibility to ideas, so a little more exposition might help in this case.
1 The Final Battle Shouldn't End So Anticlimactically
After Pucci has created his third Stand, Made in Heaven, he's granted power over time itself and accelerates it to incomprehensible speeds. He can move faster than stopped time and easily defeats the JoJo crew, decimating even Jolyne and a re-powered Jotaro. The world gets remade as an alternate universe and Emporio manages to kill Pucci using a hidden ability of Weather Report's Stand, which he received earlier in the story. As Stone Ocean's protagonist, Jolyne should play a bigger role in Pucci's defeat.
