Jotaro Kujo and Dai may have been revealed for Jump Force
Some hastily removed ads featured the characters, but quick screenshots indicate that they're coming to Bandai Namco's game.
Sometimes companies make mistakes and post information a bit quicker than intended, and it looks like adverts for Jump Force may have done just that. These were spotted on both Facebook and Instagram, and as shared by Twitter users like YonkouProductions, Jotaro Kujo from JoJo's Bizarre Adventure and Dai from Dragon Quest: The Adventure of Dai look like they're coming to the game.
Of course with leaks like these we can't be 100% sure if they're legitimate, but as you can tell from the subreddit there's a lot of buzz around these characters. Stay tuned for an official announcement, but it seems as if we might see the two characters unveiled sooner rather than later now that word is getting around.
