Officer Jenny is the local law enforcement leader in the Isshu region. Each city and area has a Jenny who looks exactly the same as she does elsewhere in the Isshu region though they do look different compared to their Jenny counterparts elsewhere in the Pokémon World.
The most noticeable different between Isshu region Jenny and those from elsewhere in the Pokémon World is their haircut. They have a butch looking haircut that is popular with many lesbians.

Gigaiath and Champion Master Adeku
In
BW54,
Alder was seen sitting in the sidecar with
Officer Jenny's Herdier. The two seemed to get along quite well despite
Officer Jenny (Unova) instance that
Alder carry on with his business.
Alder noted to
Officer Jenny (Unova) that her Herdier looked happy to get his attention.
Officer Jenny (Unova) was not impressed with his attempts to go on a date with her and she threatened to arrest him if he didn't leave her alone. She couldn't believe that he was actually the Unova region Elite Four Champion.
Later on in the day, the two met up again as a raging Gigaiath threatened Raimon City.
Alder came to the rescue and taught
Officer Jenny (Unova) a lesson in humility and observation as he was able to stop the raging Gigaiath despite her attempt to intervene and stop it herself by force.
Officer Jenny (Unova) wanted to guard and supervise the Gigaiath but after it saved her from being crushed by a falling pillar, she realized that the nail that was removed from its foot was the true reason that the Gigaiath was raging and
Alder had recognized that. Her opinion of Gigaiath and
Alder seemed to change after those events.
