wasn't really a manga but anime the first ones were DBZ #1, pokemon #2, then Yu-gi-oh #3, the final converter was youioh and the only reason was that when i grew up on dbz and pokemon i thought they were cartoons not anime... it wasn't until a i got older and learned of yugioh that they were anime ( i grew up in Jamaica and the stations the we got on TV were American stations and i watched a lot of cartoon network so yeah)also in school kids would bring pokemon and yugioh cards to school and some had the ones in the original Japanese language that's what convinced me.
