This thread will essentially ask 2 questions, although you don't have to give your answer both questions, I would prefer if you did.
1st Question: What if 4kids NEVER DUBBED One Piece, do you think that One Piece would've surpassed "Nardo the ninja (and his magical quest to save his boyfriend Sausage)" and "Bleh (A.K.A. Yu Yu Hakusho 2.0)" levels of popularity, or do you think that it would've floundered like it did with 4kids at the helm.
2nd Question: What if 4kids STILL DUBBED One Piece, just how bad do you think they would've fucked up Skypiea, Water 7 and so on,
They probably would've deleted certain characters and arcs (Such as Ivankov and the Marineford War) and they probably would've airbrushed some shorts on Franky and make him sound like a cross between a Surfer and Arnold Schwarzenegger, and they probably would've fucked up Brook's backstory and make him sound like Grim from Billy and Mandy.
