Benny Demario is a character of the day who appeared in Those Darn Electabuzz!.

Benny is the younger brother of Corey Demario, star pitcher of the Electabuzz baseball team. Corey gives Benny a Charizard—nicknamed Don—which had lost its fire and ability to fly. This paralleled Corey's own fears.

Casey helped the pair regain their confidence, and Don was presumably returned to Corey at the end of the episode.
