8. Porygon, Seizure Extraordinaire
http://www.youtube.com/watch?v=Y3bKOzjw9KE Many may not not know this, but there was an episode originally released in Japan which was surrounded upon Porygon, the first man-made Pokemon and the episode was so dangerous that it had to be immediately pulled for safety reasons. The story is that the episode, titled "Computer Soldier Porygon" was aired in Japan, but due to the severity of flashes and lighting effects used in the episode, it gave hundreds of kids seizures and to say the least, the hospitals had a busy time during the air date. As of this, the franchise had to make a humble apology and make sure that the episode was pulled, never to be seen again.
