Officer Jenny encompasses a family of indistinguishable police officers using the same name across multiple regions like Sinnoh. Regional uniform differences and unique hat badge symbols distinguish them, with Brock frequently recognized as the only person able to spot their subtle variations. The Sinnoh region Officer Jenny wears a purple cap with a black rim, red top, and gold star. Her uniform features a purple collared shirt trimmed in red, a sky blue chestpiece, gold shoulder pads, a matching belt with a gold buckle, a purple skirt, black high heels, and white gloves. This uniform design remains consistent for her counterparts in Kanto, Johto, Hoenn, and Sinnoh. Specific Sinnoh Officer Jennys include: - The Sandgem Town Officer Jenny, who helps Ash locate Pikachu and reunite him with Dawn at Professor Rowan's laboratory. - Her sister, the Jubilife City Officer Jenny, who pursues Team Rocket's theft of machine parts from a factory but doesn't catch them during their escape. - The Eterna City Officer Jenny, who patrols daily with her Stunky, using its poison-based abilities to subdue suspects. - A Kanto Officer Jenny appearing in Sinnoh with her Chatot partner Pokémon, explicitly tracking Team Rocket due to their history of following Ash since Viridian City. Sinnoh-based activities include her participation as a judge in the Pokémon Dress-Up Contest wearing a Growlithe-themed hat, alongside Mr. Sukizo and Nurse Joy. She also enters a Pokémon Hustle event undercover to track and arrest criminals named Crimson and Azure. Her primary Sinnoh partner Pokémon is Growlithe, used for crime-solving, pursuing suspects, and battles; it defeats a Drowzee during the arrest of Azure and Crimson. Additional Sinnoh Jennys utilize Stunky and Chatot. Growlithe employs moves such as Ember, Flamethrower, Take Down, and Roar. In broader developments beyond Diamond & Pearl, one Kalos Officer Jenny falls under a rogue Malamar's control, temporarily adopting the "Madame X" identity to advance the Malamar's goal of reviving the Ultimate Weapon, unaware of her actions during this time.
