Sonic is basically what got me invested in voice actor swaps lol. I literally can’t stand some of the voice actor swaps in that series because they just sound so drastically different and wrong.

Voice issues happen a lot with anime too when it gets dubbed. Rarely will the dub be better, but there’s some iconic dubs like the pokemon cast, or haruhi. With the yuki-chan spin-off series of haruhi, I was really concerned they’d get different VAs and it’d be ruined as a result, but fortunately they had brought back the entire original cast.
