I think Dogasu once made a comment that if 4kids was still running the show, characters like Paul and Pokehunter J either wouldn't exist or they would be toned down considerably.
Anyone find it interesting that in the saga right after 4kids stops dubbing, we get these truly cruel or evil characters in the anime? Can you imagine the Paul beating Chimchar with his other Pokemon done under 4kids?
4kids would have also definitely lengthened Dawn's skirt, according to the edit page on Dogasu's website, they did it a number of times with Jessie. Do you honestly believe they'd let Dawn prance around in a tiny skirt like she does?
As for fanservice, one thing I found interesting is 4kids didn't have a problem with May basically stripping on Dewford beach in front of everyone, nor did they have a problem with Harley's gay mannerisms, but they DID have a problem with Norman cheating on Caroline, which is why they had to make it slightly less obvious in the dub. So apparently cheating is bad, but blatant fanservice is ok unless it goes to extremes?
Anyway, thank goodness 4kids can't edit anymore. We're getting truly cruel or evil characters in the anime, everything Dawn does is left alone, and the writers are allowed to be truly creative.
4Kids would also have edited out the infamous panty shot from "Pikachu's in Charge/Steamboat Willies" even though it only flashes by for less than a second.
