Pokémon first aired on September 7th, 1998 in America on local stations around the country.  It had a slow start, but soon got blown up into the monster we see today.  Would you like to know what changes were made to the series?  You've come to the right place.

Inside each episode comparison, I have several symbols:

= Cultural change.  Something Japanese was mainstreamed for the American version so it's less Japanese.
= Edit.  Almost every hiragana, katakana, and kanji character have been removed and replaced with either English or a picture of some sort.  Find out what the signs originally said in Japanese.
= Cut.  This was a scene cut or altered because the TV censors didn't like them.  Stuff like Kojirou's breast scene, Nyasu's use of a lighter, or Mushashi getting spanked.  Also find out about cover-up lines (like calling bombs "blaster balls").
= Rocket Dan.  The Rocket Dan periodically change their motto (Lovely-Charmy Salon, the Yamato/Kosaburo motto, etc.).  This symbol indicates whenever the motto's different.

In the more recent comparisons, these symbols are being replaced by bold/underlined text.  Episode comparisons with the symbols above were done from the Japanese anime books--basically, what Pokémon Power consisted of back when Nintendo Power still printed those.  While these are good sources of information, they aren't the same as having the real episode to compare with, so they are most likely incomplete. 

Also note that whenever I use the dubbed names in the comparisons, I'm talking about the dubbed version.  When I use the Japanese names, I'm talking about the Japanese version (unless it's in one of the older comparisons).  So saying "Mewtwo is more shallow than Myuutwo" is the same as saying "The dubbed version of Myuutwo is more shallow than the Japanese version."  It's just more concise.

Below is a list of the various fan-designated sagas of Pocket Monsters, Pocket Monsters Advanced Generation, and Pocket Monsters Diamond & Pearl.  When you click on a season, you'll reach a list of the episode titles and links to comparisons.
