Officer Jenny is not a single entity. Rather, there are many Jennys working as police officers across the various regions of the Pokémon world. Generally, Officer Jennys are brave and determined, but can be ineffective in their police duties. They fight against the likes of Team Rocket, Team Magma, Team Aqua, and Team Galactic, among other miscellaneous criminals. Although there are many exceptions, Officer Jenny will generally have Growlithe to use as a police dog.
