Anime: Brawly is in charge of the Knuckle Badge and resides in Dewford Town. Brawly's name contains the word brawl in it, referring to fighting; his Japanese name TÅ�ki can be literally translated as "fighting spirit." Brawly specializes in Fighting-type Pokémon, and once trained alongside Kanto Elite Four member Bruno. In the Pokémon anime series, Brawly is a Gym Leader who likes to Surf and train his Pokémon at the same time. His Pokémon move like the waves, always changing and avoiding attacks through the course of battle. He also has a private island which has a training facility and a battle field that has many geysers on it. Ash loses to Brawly the first time, when he relies only on brute strength. However, in the rematch, his Corphish and Treecko use the forces of nature to defeat Brawly's Machop and Hariyama. Manga: Brawly also trains his Pokémon by surfing with them in Pokémon Adventures. His strategy is to use "subtle forces" over speed and power to use his opponents' strength against them. He also likes to save his Pokémon's evolutions for battles. During his match with Sapphire, his Makuhita evolved into Hariyama. Sapphire figured out that his use of Counter could be overcome by moves which attacked with multiple hits, such as Double Kick. Due to a misunderstanding, she was also expecting Brawly's Pokémon to evolve. Brawly sided with Team Aqua in the Hoenn conflict because he wanted more places to surf. He changed his mind after Kyogre and Groudon started their rampage. His opponent during the Kyogre/Groudon fiasco was Mack. Using direct, brutal strength instead of his usual strategy, he defeated him at the cost of his own Pokémon. He was last seen on the Pokémon Association's airship "Ba.Goon," resting from his injuries.
Tate is known as the 7th gym leader along with his twin sister Liza in Mossdeep, Hoenn. In the anime, he is always picked on by his sister Liza for being a couple of minutes younger than she is (and thus is inexperienced compared to her). His prized pokemon is Solrock.
Falkner's only anime appearance was in the episode Fighting Flyer with Fire. When Ash's Pikachu gets stolen by Team Rocket, Falkner arrives and rescues Pikachu with the help of his Pidgeot. He flies around on a glider, yearning to be as close to Flying Pokémon as he possibly can be. He is usually seen with his Hoothoot on his shoulder. Falkner has a self-righteous attitude when it comes to Pokémon training, which tends to anger Ash. Falkner also expresses an intense dislike for the prejudice against the Flying-types' weakness to Electric-types, but proves a slight hypocrisy as he criticizes Ash's poor choice of using Chikorita (weak to Flying-types) in their match. The Violet City Gym itself is a very tall, spiral-shaped building. Falkner has his matches on the roof of the Gym. Falkner has many students who chant in unison during his battles. Ash was able to win the Zephyr Badge, despite his Charizard's wing being severely injured during the match.
Erika is the Gym Leader of Celadon City's Gym, known officially as the Celadon Gym. She hands out the Rainbow Badge to trainers who defeat her. She is a serene young woman who specializes in Grass-type Pokémon. She sometimes dresses in elegant kimonos and seems to represent traditional Japanese beauty, and perhaps geisha culture.
Lucy appeared in the episode Queen of the Serpentine!. In the anime, it was mentioned that she does not teach her Pokémon defensive moves. Before battling Ash, she had rescued his Pikachu from Team Rocket with her Seviper, defeating Jessie's Seviper in the process. In the battle, Ash started off by using his Donphan against Lucy's Seviper. For a while, Lucy seemed to be having the upper hand despite the type disadvantage. However, Ash managed to turn the tables on the serpent Pokémon by using Donphan's Rollout to counter Seviper's Flamethrower, knocking it out of the battle. Lucy then sent out her Milotic which easily took out Donphan with just a single powerful Hydro Pump attack. Left with no other choice, Ash decide to use Pikachu. However, again, despite the type disadvantage, Lucy almost managed to defeat the electric-mouse Pokémon by treating it to a barrage of Hydro Pumps and Twisters. She even used paralysis to her advantage by using Facade. Ash finally managed to defeat it and win the match when he innovated a move by making Pikachu jump inside one of the twisters and using a spinning Volt Tackle. In addition to her preference of serpentine Pokémon, Lucy also seems to have a soft spot for squinty eyes, as she was shown to keep several pet Pokémon at home, all of which had squinty eyes. She develops a crush on Brock due to his squinty eyes. Lucy in the anime is very different from her game self personality wise. In the anime, though quiet, Lucy seems to be a rather a nice person, allowing Ash to battle her even though the Pike was closed that particular day. She also congratulated him on his victory. In the games, however, she is narcissistic and seems to be very irritated when the player defeats her. Her change of attitude in the anime can be attributed to her crush on Brock and a desire to impress him.
Anime: Scott first appeared in The Scheme Team. After observing Ash's battle against Agatha, Scott recommended that Ash go to the Battle Frontier. He next appeared in Numero Uno Articuno to observe Ash's battle against Noland. After that, Scott appeared at every battle facility to observe Ash's battle against the resident Frontier Brain. He hasn't been seen since Ash defeated Brandon. In Gathering the Gang of Four!, it was revealed that Scott is the owner of the Battle Frontier. According to him, he created the Battle Facilities to expand the art of Pokémon battle. In Pace - The Final Frontier!, Scott asked Ash to be a Frontier Brain after he defeated Pyramid King Brandon, the last Frontier Brain. Ash declined. Due to the fact that he wears sunglasses often, his eyes are almost never seen. Scott is also known for reckless driving. He drives rather fast, regardless of what kind of terrain he is on. Manga: In correspondence with Pokémon Emerald version, Scott appears as the founder of the Battle Frontier in the Emerald chapter of Pokémon Adventures. He also makes a cameo in the Ruby and Sapphire chapter during the fight between Groudon and Kyogre.
