Gym Leader

A Gym Leader (Japanese: ジムリーダー Gym Leader) is the highest ranking member of a Pokémon Gym. The main job of a Gym Leader is to test Trainers and their Pokémon so that they are strong and resourceful enough to compete against the Elite Four in the games or the Pokémon League in the anime. If a Trainer defeats a Gym Leader in battle, then the Trainer earns that Gym's Badge. Once a trainer has earned 8 badges from a region, he or she is able to compete against that region's Elite Four or Pokémon League.

A Gym Leader's job is not just to test upcoming Trainers. They must oversee how their respective gym is run and to maintain it. Great care must be taken to make sure that their gym reflects the best environment for the Pokémon type and playing style of choice, usually an environment that suits that type of Pokémon used there (like pools in a Water-type gym or flowers and plants in a Grass-type gym). According to Morty, teaching young people how to battle with Pokémon can also be the job of a Gym Leader. In the games, Trainers must overcome various obstacles and challenges from other Trainers before they can challenge the Leader. Gym Leaders may also be involved in other activities when they are not battling other Trainers or training themselves, usually something to do with their town's particular attraction or landmark. Gym Leaders can also leave their gyms without notice (as Blue, Giovanni, Jasmine, and Wallace do), and even challenge other Gyms and the Elite Four (like Volkner wanted to do).

It has not exactly been made clear how Gym Leaders attain their position, but it appears that it varies for each gym. Some of them founded their gym and are self-appointed, others appear to be passed on through families, while a few are chosen by the other members of the gym. In the manga series, Red and Falkner have to battle with Pokémon set by the Pokémon League, where those Pokémon are not controlled by Trainers and challenger is not allowed to let any of his Pokémon faint.

Although similar in nature, Frontier Brains are not considered Gym Leaders and are thus not included in this list.

Trivia

• The three Electric-type Gym Leaders all have light colored hair. Lt. Surge and Volkner both have blond hair, and Wattson has white hair.
• All Gym Leaders of the player's region give away a TM on their defeat, and all but Brock in Generation I and Falkner in Generation II give away a TM containing their specialty type of move. Interestingly, Brock's Normal-type Bide and Falkner's Ground-type Mud-Slap are of the other type of the Pokémon on each other's teams (Falkner has only Normal/Flying Pokémon while Brock has only Rock/Ground Pokémon).
  • Of the Generation II Kanto Gym Leaders, only Janine and Erika give away TMs, containing Toxic and Giga Drain, respectively, continuing the type-specialty trend.
• Every Gym Leader that specializes in Rock-type, Ghost-type, and Steel-type Pokémon uses Geodude, Gengar, and Steelix respectively in battle.
• Johto is the only region that did not repeat types from gyms released in previous generations. This is likely due to the fact that there had been only eight gyms before, while there were seventeen different types.
• Even though there are thirty-two known gyms in the games, there has not yet been a gym specializing in Dark-type Pokémon, although there have been two Elite Four members, Karen and Sidney. Only Poison-, Ground-, Bug-, and Dragon-type gyms are not located in multiple regions. Each of the twelve other types has been repeated at least once, and Rock-, Water-, Electric-, and Fighting-type gyms appear in three of the four regions.
• There have been more male Gym Leaders than female ones in every region except for Sinnoh, where there are four of each. Kanto also has four of each in Generation II.
• So far, all Electric-type Gym Leaders have been male, while all Grass-type Gym Leaders have been female.
• Even though they were called Leaders in Generation I, this title did not appear in battle until Generation II.
• The only Gym Leaders so far whose parents have been seen in the anime are Brock, Sabrina, Tate and Liza, and Roark. They all train either Rock-type or Psychic-type Pokémon.
  • Roark and Maylene are the only ones who have a parent the player can encounter in the games.
• In the anime, Gym Leaders seem to be forbidden from switching their Pokémon. Those that Ash encountered before Blaine did switch; however, since Ash's match against Blaine in Riddle Me This, Gym Leaders have not switched out their Pokémon. In the games, they may switch their Pokémon as often as any other Trainer.
• For Setting the World on its Buneary, Professor Oak's lecture is about Gym Leaders. He writes this Pokémon senryū about them: ジムリーダー　いのちをかけて　かかってこい Jimu Rīdā / Inochi o kakete / Kakatte koi "Gym Leader, put your life on the line and challenge me"
• In the Johto saga of the anime, none of the Gym Leaders had the exact same lineups as they do in the games.
  • Falkner's Pidgey and Pidgeotto were completely replaced by Hoothoot, Dodrio, and Pidgeot.
  • Bugsy used his in-game team, but had a Spinarak in place of Kakuna.
  • In addition to her in-game team, Whitney had, strangely enough, a Nidorina.
  • Morty used his in-game team, minus the second Haunter.
  • Jasmine used her in-game team, minus the second Magnemite.
  • Chuck used a Machoke instead of Primeape.
  • Pryce used his in-game team, minus Seel.
  • Instead of three Dragonair and a Kingdra, Clair used Gyarados, Kingdra, and only one Dragonair.
• Only in Johto-based games is it possible to battle former Gym Leaders who have become ordinary Trainers, as Eusine appears in Pokémon HeartGold, SoulSilver, and Crystal and Giovanni appears in Pokémon HeartGold and SoulSilver. Wallace and Koga, themselves formerly Gym Leaders, are faced as a Champion and Elite Four member, respectively, in later appearances.
• Since Generation II, each of the 8th Gym Leaders in each region have some relation to the Elite Four.
  • Clair is Lance's cousin.
  • Blue is the former regional Champion.
  • Wallace would be a Champion and Juan is his mentor.
  • Volkner is Flint's friend.
