Title: Re: JOHTO 30: Sonans to Pokémon Kōkankai!!/ソーナンスとポケモンこうかんかい!...
This episode reminded me that the Rocket Gang Pokémon never really changed over the course of the 3 main series (Original, Advanced and Diamond). They'd often keep the same for an entire sub-series... especially since they always had at least 4 free slots in both Kojiro AND Musashi's team... I know they're quite incompetent at stealing other people' Pokémon, but that doesn't mean they couldn't some fresh Pokémon another way.
