J

J (also known as Pokémon Hunter J), is a ruthless and cruel Pokémon hunter around Sinnoh who caught and stole Pokémon and sold them in the black market for money.

Biography
J appeared in Pokémon Diamond and Pearl, with her army of henchmen whose primary means of transportation were advanced 6-wheeled armored trucks. The trucks were used to take all the Pokémon they captured to J's airship, so that they could be sold on the black market. Her airship's capabilities included lasers, a cloaking device, a high-tech visor to follow Pokémon that got away using teleport. The ship had a gun that steamed gold cement, which was used to turn Pokémon into statutes, as well as strong glass cases to contain Pokémon.

Hunter J has shown interest in Ash's Pikachu, as well as Team Rocket's Meowth. She managed to turn both Pikachu and Meowth into stone, but Ash, his friends, and Team Rocket members, Jessie and James, managed to save all the Pokémon that I had turned to stone.

I attempted to capture the legendary Pokémon, Regigigas by forcing it to wake up with her Salamence's Flamethrower while the Pokémon was at Snowpoint Temple. Despite this, she was unable to capture Regigigas due to the efforts of Pyramid King Brandon and his Pokémon. J immediately withdrew from the area when her client decided to cancel the deal regarding Regigigas

Unlike other villains who have appeared in the series, J is one of the few who have not been defeated or been arrested by police.

Ash and Gary were determined to rescue a group of Shieldon captured by J, Gary said to Ash Ketchum that since they had recovered the Shieldon it was enough. Later on Ash teamed with a "High Ranked" Pokémon Ranger (in which he's called a Top Ranger) who's protecting a Riolu from J in order to bring it to her client and not even they could defeat her.

Hunter J does not care about the wellbeing of people, Pokémon, or even her own henchmen.

J and her goons went down with their ship after it was hit by Uxie and Mesprit's Future Sight attack while attempting to capture the Pokémon for Team Galactic. Team Rocket claimed to their boss, Giovanni, that they were responsible for J and Team Galactic's defeat, causing their promotion. It is unknown if she or her Pokémon survived the explosion.
