It has been announced by TV Tokyo that the originally planned episode due to air this week in Japan, The Castle on the Seabed! Skrelp & Dragalge!!, has been postponed. This episode featured Ash & co. investigating a sunkern ship and city with Skrelp and Dragalge. The reasoning for the delay has yet to be confirmed but presumably relates to an incident last week involving the sinking of a boat. In its stead, the next episode, The Cyllage Gym Match! Pikachu VS Tyrunt!! is to air. It’s unknown when the episode will eventually air or what episodes have had changed airdates.
Note the part I underlined. In case you’ve been living under a rock, a ferry capsized and sank in South Korea last week, taking the lives of almost 300 people with it, most of them school children. Anyone who’s been following the Pokemon Anime for as long as I have knows this isn’t the first time an episode’s airing has been delayed due real-life events. You can see the full list of banned episodes on Serebii.net for yourself if you want.
Except for Episode 35: The Legend of Dratini, none of the banned episodes had a longterm impact on the storyline. That episode’s the exception since Ash catches 30 Tauros in it and unlesss you knew the episode was banned in the U.S. you’d have never known how or when Ash caught the Tauros, who appear in a later episode. As I understand it the banned episodes are NOT included with the Indigo League DVD set since they were never officially aired. 4Kids and Nintendo have yet to comment on why this episode has never been aired in the U.S. almost 20 years later.
As for the recently announced postponed episode, I don’t see it getting aired at least for a few years if they decide to air it later. Except for the episode I mentioned above, all of the epsiodes that have been banned/delayed don’t have a longterm impact of the series. As an aisde, it’s interesting to note Porygon, Porygon2 and Porygon-Z have never made an appearance in the Anime since the imfamous Electric Soldier Porygon episode XD
