The game was censored for the international release. The reason for this were the guidelines of Nintendo USA, which were designed to give the company a family friendly and rather conservative image. Because of this a lot of violence, suggestive themes and religious aspects were removed from countless games. This also happened to Pokémon Gold/Silver/Crystal. As was the case quite often, the US game was then used as a basis for every other worldwide version. It seems that only the Japanese Version is really uncensored.
