Uhm, yeah. ^_^;; Pokemon was initially a Japanese video game created for Nintendo’s Game Boy by Satoshi Taijiri. (For whom the main character in the game was named) The marketing blitz here OR there didn’t even come into it until the game had become rather popular.
Additionally, the anime is also authentic. I’ve seen it raw. (The incomparable Megumi Hayashibara is great as the female half of Team Rocket) Any other shtuff may or may not be Japanese, though. I’m not sure.
On another topic, bad guys DON’T always have squinty eyes. Many do, but there’s plenty of villains who don’t (often though not always comedic villains) as well as protagonists who do. It depends on the genre, and sometimes the series. Also how you define “squinty” eyes.
