In the original Japanese version, Casey speaks with a Kansai dialect, which residents of Osaka, Japan speak. Kansai, along with Chūbu, is one of the regions of Japan that Johto is based on. Adding to this is Casey's love of the Electabuzz baseball team, an analogue to the real world Osaka baseball team, the Hanshin Tigers. Not only is there a similarity in both Electabuzz and tigers being striped animals, but the Hanshin Tigers are known for having a very loyal fanbase.
