Trivia / JoJo's Bizarre Adventure: All Star Battle
Beam Me Up, Scotty!: Despite what the memes would have you believe, Funny Valentine's Stand's name in the English version of the game is "D4C", not "Filthy Acts at a Reasonable Price." While he does say "Time for some filthy acts at a reasonable price!" in one of his intro quotes, that's just a sneaky copyright-dodging in-joke; any time he refers to his actual Stand, the subtitles call it "D4C".
The fourth trailer began with the words "To all those that love JoJo".
I Knew It!: JoJolion!Josuke's appearance, although many fans had written him off.
Same with Kosaku's inclusion for a mild-sized group of fans.
The Other Darrin: A whole new voice cast was introduced for practically every single character that appeared in other voiced-adaptations, which would stick onto their other appearances onwards. A sizeable amount of the said VA's also tend to be those who voiced other characters before being switched onto another one, giving them more than one JoJo character on their resume, examples include:
Houchuu Ootsuka, who originally voiced Young Joseph Joestar in the Capcom game, while instead voicing Hol Horse in All-Star Battle.
Likewise for old Joseph, Touru Ookawa originally voiced him in the Capcom game, while he now both the narration (especially for Baoh) and also voicing Weather Report from Part 6.
Mitsuaki Madono no longer voices Kakyouin from the Capcom game, while now instead voicing Part 8 Josuke Higashikata.
Shou Hayami voices another follower of DIO by the name of Enrico Pucci from Part 6, while in the old Capcom game he voiced Vanilla Ice from Part 3 (which would be a Role Reprisal for the official Part 3 anime and Eyes of Heaven on Vanilla Ice's part).
Rikiya Koyama originally voiced William A. Zeppeli in the PS2 Part 1 game, but instead voices both versions of Yoshikage Kira.
