Gaoranger to Wild Force was more or less a direct translation with a few things being changed here and there, such as:
-Gaored was a Vet, while Wild Force Red was a jungle boy (while being a bit hammy and over the top with cheeseyness)
-Master Org himself was just an actor putting on the suit from a villian from Gosei Sentai Dairanger.
-GaoYellow being male while Wild Force Yellow being female.
Oh god, that's right....In the Time Force/Wild Force team up special, Ransik calls Jen "Timeranger" when speaking to her. While in America, Time Force had used the Super Sentai footage from "Mirai Sentai TIMERANGER". Maybe its just a coincidence, but I chuckled at that little bit of a call out to Timeranger.
I forget how many more changes where thrown in here for Wild Force, but the point still stands that its more or less a direct translation from Gaoranger.
