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.

You really shouldn't sit too close to the TV
30 July 2017 | by Eric StevensonSee all my reviews

This is it, people. This is the pokemon episode that appeared on Wikipedia's list of unusual articles because it caused seizures in Japanese children. Porygon's evolutions are the only pokemon to never appear in the anime because of this. Actually, it was Pikachu that was in the scene that caused the seizures who then went on to appear in literally every episode afterwards. Wow! I guess Porygon is the pokemon equivalent of Muhammad. If they did an episode with Porygon's evolutions, would the creators get death threats? So many people have referenced this episode, more so than any other anime episode ever made.

As for the actual episode itself, I actually really enjoyed it. It features the Pokeballs being blocked in the teleporter so the characters have to literally go inside the teleporter to fix it. Porygon is actually a really cool pokemon! I loved how it could shapeshift and turn into various weapons. Honestly, it was such a waste with its evolutions never appearing in the anime. There were a few cameos by it later but of course never an episode focusing on it. I love how Team Rocket just thank them and run away at the end. ****
