I think it was so people don't get confused and think it's the fourth installment of the anime. It's not confusing to Japanese fans because they know what "Kai" means.Mewzard wrote: As for the Z in Z Kai, remember, it was Toei's doing to have Z added in the Funi release, likely due to Z doing better than the other releases, and Toei liking every scrap of ad work and cash they can get.
Adding the "Z" makes much more sense and I'm glad it's officially called "Dragon Ball Z Kai" in the English market.
