Forrest (Japanese: ジロウ Jirō) is a recurring character who appeared in the Pokémon anime. He is a Rock-type Pokémon specialist and the current Gym Leader of the Pewter Gym. He gives the Boulder Badge to Trainers who defeat him in battle.

Forrest is the brother of Brock and eight other children and is the son of Flint and Lola. He is the second-oldest child in the family.


Pre series

Years ago, Forrest's father Flint left home to become a great Trainer and never returned. His mother Lola soon followed. This left his eldest brother Brock in charge of the family. Brock took care of them for many years, running the Pewter Gym at the same time. However, Brock secretly wanted to travel and become a Pokémon Breeder.

Original series

Forrest and his other siblings

In Showdown in Pewter City, Forrest is first seen when Flint introduces Brock's family to Ash. While Brock was taking care of the house, Forrest was studying with his two other siblings. During Ash's rematch against Brock, Forrest and his brothers prevent Ash from continuing the match and defeating Brock, causing Ash to decide to stop the battle.

In the end, when Flint decides to return home, it allows Brock to go on a journey with Ash and Flint takes care of Brock's brothers.

Pokémon the Series: Ruby and Sapphire

Flint ran the Gym in Brock's absence, but was ousted from the position when Lola returned home prior to A Family That Battles Together Stays Together!. Lola usurped the title of Gym Leader from Flint and turned the Gym into a Water-type Pokémon Gym, something that angered Forrest, who was dedicated to Rock-types.

Brock returned home and was shocked to find out what happened. Forrest and Brock commiserated with each other over the sad state that the Gym had fallen into. Brock went on to defeat Lola in a battle, and convinced her to restore the Gym to its former state as a Rock-type Gym. Forrest also revealed that he was yet to obtain his first Pokémon, though Brock lent Forrest most of his Pokémon and passed the title of Gym Leader on to him.

In Grating Spaces, Brock, Ash, May, and Max visited the Pewter Gym as they traveled around Kanto in search of the next Battle Frontier facility. Forrest alerted Brock to the Gym's latest makeover, courtesy of a trio of Gym stylists, who turned out to be Team Rocket. Brock and Ash went on to defeat Team Rocket and rescue the Gym. Brock was also impressed to see that his Onix had since evolved into a Steelix under Forrest's training.

Pokémon the Series: Diamond and Pearl

Forrest and Brock

When Brock returned from Sinnoh in DPS02, Forrest was with a Nurse Joy from the Pokémon Inspection Agency, but she demanded to see the true Gym Leader, Brock. Brock battled Joy and Forrest acted as the referee. However, Brock lost and Joy was about to close the Gym, but she gave them one more chance after it was revealed that Flint hadn't delivered the paperwork to officiate the Gym Leader change. If Forrest battled her and won, she would not shut down the Gym. He was surprised when Joy called upon her Latias, a Legendary Pokémon. Forrest put up a tough fight with his Rhyperior, but both ended up losing to Latias. Still, Joy was impressed by his skill and decided to name him as the official Gym Leader of Pewter City.

Pokémon the Series: Sun & Moon

More recently, Forrest and the rest of his and Brock's siblings reappeared in a fantasy during the Poké Problem segment of SM042. Brock mentioned that Forrest was still in charge of the Gym while he was doing his Pokémon Doctor studies elsewhere.


Forrest has a keen eye for strategy, having learned much from years of watching his father Flint and older brother Brock battle challengers at the Pewter Gym. His passion for the Pewter Gym was first seen in A Family That Battles Together Stays Together!, where he objected to his father's plan to have a dual Rock and Water-type Gym. Brock went on to encourage Forrest to fulfill his Gym Leader ambitions, and in DPS02, he was able to test his skills against a Nurse Joy from the Pokémon Inspection Agency.

He channels his sense of responsibility for the Gym and experience into the battle. Forrest utilizes the Pewter Gym's rocky terrain to his advantage, showcasing the very best of his favorite type, the Rock-type.

In the English dub, Forrest is somewhat girl-crazy, like his older brother Brock.


This listing is of Forrest's known Pokémon in the Pokémon anime.

On hand

Rhyperior is currently the only known Pokémon of Forrest that he did not borrow from Brock. He used it in a battle against Nurse Joy's Latias that, if he had lost, would likely have caused the Pewter Gym to be shut down. Rhyperior did a lot of damage to Latias with its Megahorn, but Latias used Recover and then fired an Ice Beam at Rhyperior. Rhyperior continued to use Megahorn, but Latias used multiple Steel Wing attacks and an Ice Beam until Rhyperior finally fainted.

Rhyperior became frozen by Latias's Ice Beam but Brock was able to help it recover. Nurse Joy was impressed by Forrest's skill, and as a result the Pewter Gym was not closed.

Rhyperior's known moves are Megahorn, Rock Wrecker, Horn Drill, and Dig.

  • It is implied in Pocket Monsters: The Animation that Forrest alongside his other siblings and possibly even Brock himself may not have been sired by Flint. It was mentioned that Lola, prior to ultimately abandoning her family, had "married again and again and had dozens of kids" in a desperate attempt to keep Pewter Gym due to her various husbands fleeing when they were losing due to the strict regulations of running a Gym.
  • Forrest is the youngest Gym Leader in the Indigo League and the only member of any lineup of the Kanto region's Gym Leaders who has never fought Ash.
