I may or may not have just guessed the ending of JoJoLands
Jodio Joestar will end up being the main villain. The final battle will be between him and Dragona, a battle between brothers mirroring Part 1. This would be a beautiful and heartbreaking way to end JoJo once and for all, and it would be a new type of enemy that Araki hasn't explored before: betrayal from one's own family.
Jodio himself seems to have all the hallmarks of an aspiring villain. (His name is literally Jo-Dio?? Too easy.) He's already shown himself to be violent and greedy. Sure the two people he beat up were police officers assaulting his brother but it still felt a bit over the top. He also works for some kind of mafia, and not for any noble reason like Giorno; he just wants to get, in his own words, "filthy rich." (And what was Dio's motivation at the beginning of Part 1?) The first interaction we see in his daily life is him selling drugs to someone at his high school, which couldn't be a more obvious subversion of Giorno's morals. Even in the way he views his relationships and society. He looks down on people who are good-natured, only caring about getting favorable results, (a common theme with villains in JoJo) viewing society not as driven by uncontrollable fate which everyone must navigate, but as a "mechanism" to exploit for its benefits
Then there's his character design and especially his stand. Tell me this wouldn't fit right in with the lineup of main villains' stands it's just so menacing
My first thought was that it looked a lot like Fun Fun Fun from Part 8, and that Araki wanted to bring back a cool-looking design. But it also looks a lot like D4C Love Train
It also has these spikes on its shoulders, just like the feathers on Dio's outfit when he became a vampire and Made in Heaven
As for Jodio himself, when I first saw him I couldn't help but think his outfit was very similar to Toru's, with the sleeveless hoodie with lots of ornamentation
It'll only be about 15 years until we see if I'm right
(Araki-sensei if you're reading this please don't change your ending just because of a prediction one person on tumblr dot com made after reading one chapter. I'll be happy as long as your vision for your art comes true. That's what JoJo has always been about to me more than anything else)
