Satoshi: [about the transfer machine error] Joy-san, just what is happening here?
Joi: What hasn't been happening? I want to know too, for example, when we transfer a Pokemon as rare as say, Kyukon, The Pokemon that arrives is switched, and the original never gets there at all! Anyway, it looks like a bug in the system is causing it.

Deserved to be BANNED!
5 September 2007 | by MaximusQ8See all my reviews

This is due to the episode #38 of the Pokemon Anime series "Electric Soldier Porygon" was deserved to be BANNED! Why? Because of a 5 second series of flashing lights (red and blue) that caused photo-sensitive children to experience seizures.

So, the Japan's Fire Defense Agency reported that a total of 685 viewers (310 boys, 375 girls) were taken to hospitals by ambulances. Although many victims recovered during the ambulance trip, more than 150 of them were admitted to hospitals. Two people remained hospitalized for over 3 weeks!

Scientists believe that the flashing lights triggered photo-sensitive seizures in which visual stimuli such as flashing lights can cause altered consciousness. Although scientists know that approximately 1 in 4,000 people (0.5–0.8% of children between 5–13 years old) are susceptible to these types of seizures, the number of people affected by this Pokémon episode was unprecedented.
