When you are on the air for as long as Pokemon is, there are going to be hiccups in production. The anime has its fair share of banned episodes both in America and Japan. In America, several episodes have been pre-maturely and retroactively banned for sexual content, violence, and racial insensitivity. In Japan, the most famous banned episode was Electric Soldier Porygon, which became infamous for being the episode that caused many kids to go to the hospital with seizures.
