In episode 24 Jojo Bizarre Adventure: Golden Wind, there is a scene where a new stand named Notorius B.I.G appears, but on the wall it's called "Notorius Chase." Why is there this difference? Is it just some mistake in the voice-acting or key animation ? The wiki page also states that the stand Name is officially Notorious B.I.G, not "Notorius Chase."
I haven't gotten to that part of JJBA yet, so this is an educated guess.
Like a number of other characters in the franchise, such as ACDC, Pet Shop, and Jean Pierre Polnareff, Notorious B.I.G. is named after a real-life musician. In a number of cases, these character names are modified in localizations presumably to avoid potential trademark issues. For instance, Steely Dan becomes Dan of Steel, Terence D'Arby is D'Arby the Younger, Kenny G is Billie Jean, etc.
I can only assume that something similar happened here. I don't have access to the episode right now, but this Reddit user suggests the same thing and reports that some of the animation was changed.
