Did you know that three episodes of the Pokemon cartoon never aired because of Earthquakes? AG101: Shaking Island Battle was unaired because of the Niigata prefecture Earthquakes, and BW 023 and 024: Team Rocket vs Team Plasma were unaired because of the Tohoku Earthquake and Tsunami. However, scenes from the BW saga episodes were reused, one from Part 1 was reused in Meloetta and the Undersea Temple, but in different colours, and the scene with Liepard using HyperBeam on a building in Part 2 was reused in Episode N' s opening. The episodes were all removed from Canon and never seen again.
So, what do you think? All the info is from Bulbapedia, just look up Banned Episodes. Hopefully the creators learned their lesson.
