| Pokémon Adventures volume 30
Volume 30 is the thirtieth volume of the Pokémon Adventures manga authored by 日下秀憲 Hidenori Kusaka and illustrated by 山本サトシ Satoshi Yamamoto. It is the first volume in the Diamond & Pearl chapter.
In VIZ Media's translation, this volume is published as volume one of a second series, "Pokémon Adventures: Diamond and Pearl/Platinum".
Platinum defeats the following Gym Leaders:
VIZ Media has started a "second series" with this volume, publishing the Diamond & Pearl chapter concurrently with older volumes from the Gold, Silver & Crystal chapter, using this volume as #1 of the second series. Although it is unknown why they decided to release a second series (most likely to catch up with the series quicker), the reason behind why they are calling the Diamond & Pearl chapter "Diamond, Pearl and Platinum" (unlike in Japan, where D/P and Platinum are two separate chapters entirely) is most likely due to the fact that there is another Pokémon manga released by VIZ Media entitled Pokémon Diamond and Pearl Adventure!, which may have caused confusion if they had titled the second series "Pokémon Adventures: Diamond & Pearl".
