Pocket Monsters is so much more different from Pokemon, besides the name.
Like Episode 28, Denno Senshi Porygon AKA Digital Soldier Porygon, the most infamous of the Pokemon episodes. An intense fullscreen blinking animation of blue and red caused the use of ambulances of 685 kids, more than 150 were admitted into hospitals. Many suffered from epileptic seizures. I got this information from Wikipedia, but I know it is true because I personally studied this episodes for a project on effects of the brain and because my friend got an epileptic seizure from watching this episode.
Now if you think about this, has there ever been an American episode of Pokemon that has ever been able to that big of damage????
