Koga's only anime appearance was in the episode ''[[EP032|The Ninja Poké-Showdown]]''.
Koga is a ninja who trains in an old mansion, the Fuchsia City Gym, in the woods outside Fuchsia City. The Gym is filled with traps such as fake mirrors, invisible walls, pits, and many {{p|Voltorb}}. {{an|Aya}}, Koga's younger sister, is one of his students.
{{Ash}}, {{an|Misty}}, and {{an|Brock}} managed to overcome the traps in the Gym and Ash was finally able to challenge Koga. Although [[Ash's Pidgeot|Ash's Pidgeotto]] initially lost to Koga's newly-evolved {{p|Venomoth}}, prompting Ash to call out {{AP|Charmander|Charizard}}, their match was interrupted when {{TRT}} tried to steal Koga's large supply of Voltorb, although they had raided the Gym with the intent of getting {{type|Poison}} Pokémon. Team Rocket was stopped by {{TP|Misty|Psyduck}}, allowing Ash and Koga to have a rematch. Pitting Charmander against Koga's {{TP|Koga|Golbat}}, Ash triumphed and won the {{Badge|Soul}}.

Koga (Japanese: キョウ Kyō) was the Leader of Fuchsia City's Gym. He is a student of ninjutsu who specializes in Poison-type Pokémon. He handed out the Soul Badge to Trainers who defeated him.

He was promoted to a Master Poison-type Trainer, and became a member of the Johto Elite Four, at some time after the events of Generation I and its remakes, but before the events of Generation II and its remakes, thus leaving his daughter, Janine, in charge of the Fuchsia Gym.

In the manga

In The Electric Tale of Pikachu manga

Koga and Aya in The Electric Tale of Pikachu

Koga makes a cameo appearance in The Electric Tale of Pikachu manga in the chapter Pikachu's Excellent Adventure.

In the manga, Jessie, James and Meowth get trapped in Koga's Gym while searching for the Hidden Village with Ash's Pikachu, a Charmander, a Squirtle, a Kangaskhan and Tommy. Their battle is only shown briefly in a montage sequence and it is unknown whether Team Rocket was victorious or not. It is also never shown if Ash himself battles Koga.

In the Magical Pokémon Journey manga

Koga makes a brief cameo in The Wal Comes Tumbling Down. Walnut, an aspiring ninja master, mentions that Koga is a big inspiration to him.

In the Pokémon Adventures manga

File:Koga Adventures.png
Koga in Pokémon Adventures

Koga was one of the three villainous heads of Team Rocket, and served under Giovanni.

Koga debuts in the Red, Green & Blue chapter in Raging Rhydon searching the Moon Stone in Mt. Moon, here Koga fights with Red and Misty and forces his Rhyhorn to evolve with a mysterious injection, revealing what happened to Misty's Gyarados when it was kidnapped, however the mission fails. Koga later tries to bump off Red in Lavender Town's Pokémon Tower, where he uses a Gastly to reanimate the corpses of dead Pokémon buried there. He also attacks Red with his Arbok. However, Blue has his Charmeleon slice Arbok in half. Under his boss's orders, he captures Articuno and brings it to Saffron City. He is once again defeated by Blue at Silph Co., albeit that he almost killed both of them by not allowing them to reach their Poké Balls by using his Muk, then almost freezing them to death with his Articuno. After he is defeated and knocked out Red gets Koga's Soul Badge and Blue uses his special Golbat to find out where Team Rocket is holding his grandfather.

Later, Koga helps the Pallet Town Trainers in the fight against the Elite Four at Cerise Island. Koga is paired with Blue and battles Agatha, but Blue first returns his Golbat to him. When the two of them finally meet Agatha, she separates them, making Blue and Koga's Golbat that he got paired up with again face Agatha's Golbat. Meanwhile, Koga's Arbok had to face Agatha's Arbok which could change its patterns allowing it to gain the upper hand over Koga. When Blue was paralyzed from a Haunter's Lick, Koga started throwing his shuriken balls. Agatha thought this was a desperate tactic, but in reality they were Pokémon holding Parlyz Heals. Koga was hoping just one of them would get to Blue, which it did. Blue then joins him, and Koga commands his Golbat to use Leech Life on himself. His blood is then put on Arbok's torso to prevent its ability to change its pattern. Without Arbok's ability, Agatha was defeated.

Or so it seemed. In reality, Agatha just pretended to be defeated and had her Gengar masquerade as Koga and Blue's shadow to slowly suck the life out of them hidden due to Koga's quick loss of blood. After traveling through the maze for a while, they found themselves back where they started with Agatha nowhere to be found. They then figured out her plan and defeated the Gengar, but not before Koga is nearly swept in the collapsing terrain of the destroyed battleground. He narrowly escapes using his Muk to defend him in his wounded state.

Unlike the other two Rocket Admins, who were instructed to return and manage their Gyms, Koga was not even reached by Giovanni. He then disappears for a time, leaving his daughter Janine in charge of the Gym. Janine is worried for her father, but opposes his criminal ties. Later in the Gold, Silver & Crystal chapter, Koga reappeared with a new partner, Bruno, who had saved Koga when Cerise was about to collapse. They trained together for a while and both of them later met their former opponents Red and Blue, whose Rhydon was drilling underground towards Ilex Forest. Towards the end of the series, Koga and Bruno found Will and Karen in the Ilex Forest and persuaded them to work together. The new Elite Four was formed, but were not seen in action until the HeartGold & SoulSilver chapter.

Two of Koga's Pokémon have unusual powers: his Arbok can regenerate itself as long as its head remains intact (see above); and his unusually small Golbat's mouth can be used almost like a magic mirror for scrying to see things from a distance, even if walls or land are in the way. Blue takes this Golbat and keeps it for quite some time before returning it to Koga at Cerise Island.

Koga also uses custom-made Poké Balls which can be thrown as shuriken—perhaps an inspiration for Falkner’s later boomerang Poké Balls.


This is a listing of Koga's Pokémon in the Pokémon Adventures manga.

Koga's Rhyhorn

Koga's Rhydon
Rhyhorn → Rhydon
Koga's Rhydon was introduced as a Rhyhorn, where it fought against Red and Pika. When it was losing, Koga injected in with a mysterious needle, forcing it to evolve. In its evolved form, it was too much for both Red and Misty to handle, and they had to escape the battle by distracting Rhydon with an electrically charged boulder. It hasn't been seen again.

Rhydon's known moves are Rock Throw and Horn Drill.

Debut Raging Rhydon
Koga's Gastly
Gastly appeared in the Pokémon Tower, possessing the bodies of the dead Pokémon that were buried there, along with Blue and his Charmeleon. Red's Bulbasaur managed to destroy it by sucking up Gastly's gas form, and expelling it in a SolarBeam, freeing Blue in the process.

None of Gastly's moves are known.

Debut Sigh for Psyduck
Koga's Arbok
Arbok is one of Koga's most powerful Pokémon. It can regenerate itself even if it's cut in half, so as long as its head remains intact. It was used against both Blue and Agatha. It also possesses the ability to temporarily control a detached body part, such as its tail.

Arbok's known moves are Acid and Glare.

Debut That Awful Arbok
Koga's Golbat
Main article: Koga's Golbat

Koga's Golbat is much smaller than the average Golbat. Its Supersonic can be used to create a magic mirror for scrying to see things from a distance, even if walls or land are in the way. After Blue defeated Koga at Silph Co., he stole Golbat to locate Professor Oak but later returned it to its rightful owner on Cerise Island.

Debut That Awful Arbok
Koga's Grimer
Koga wears a Grimer on his shoulder in the form of a ninja outfit in Pokémon Adventures. He used it extensively to smother Blue, preventing him from breathing and restricting his movements so that he would be unable to call on his Pokémon.

None of Grimer's moves are known.

Debut Go For the Golbat
Koga's Ekans
Koga has an Ekans on his arm. It was used first to dispatch Blue's Scyther in Silph Co., and during the battle of Cerise Island to get a Parlyz Heal it held to Blue. Ekans was later used in the HeartGold & SoulSilver chapter, where it fought with Bruno's Hitmonlee against Lance's Dragonite, but they were easily overtaken by its Hyper Beams.

None of Ekans's moves are known.

Debut Go For the Golbat
Koga's Muk
Koga's Muk was used on Cerise Island to battle the Elite Four, and proved useful in his survival after the island began to crumble. In the HeartGold & SoulSilver chapter, it was used during the Circle Push event of the Pokéathlon.

Muk's only known move is Poison Gas.

Debut Karate Machop!
Koga's Weezing
Koga's Weezing was used on Cerise Island to battle Agatha, mostly to bide time until Arbok regenerated.

Weezing's only known move is Smog.

Debut Weezing Winks Out
Koga's Koffing
Koga used Koffing against Agatha on Cerise Island. It was instrumental in defeating her Gengar when it used its gas to convey a message to Blue.

None of Koffing's moves are known.

Debut Striking Golduck
Koga's Tentacruel
Koga used Tentacruel to help Red and Blue as the two Pokédex Holders were digging to the Ilex Forest.

None of Tentacruel's moves are known.

Debut The Last Battle X
Koga's Articuno
This Articuno was originally seen at the Seafoam Islands. Even though Red stopped one attempt, Team Rocket was finally able to catch this legendary bird because of its energy loss, and had it sent over for Koga afterwards. During the battle between Red, Blue, Green and Lt. Surge, Koga and Sabrina, it was merged with Zapdos and Moltres to create Zapmolcuno after Sabrina took matters into her own hands. Once defeated and freed, it returned to the wild, where it was later caught by Green alongside its fellow legendary birds.

Articuno's known moves are Blizzard, Ice Beam and Fly.

Debut You know... Articuno!

  • Koga is the only male Poison-type specialist.
  • In the manga Magical Pokémon Journey, the ninja-in-training Walnut is an admirer of Koga.
  • Out of the original Generation I Gym Leaders, Koga has the fewest Trainer cards in the Gym Leader sets of the TCG. Incidentally, his only Trainer card besides the basic Koga card had to be edited because it featured a manji, which could have caused controversy between cultures; the infamous Nazi swastika is a reversed manji.
  • Because he became a member of the Elite Four in Generation II, he is technically the first member of the Elite Four seen in the anime, though he was not a member at the time he was shown. He is also the only one Ash defeated in battle (again, however, it was as a Gym Leader).
  • In Pokémon Diamond, Pearl, and Platinum, the Ninja Boy on Route 217 mentions different kinds of ninja in the world. He says, "There are several kinds of ninjas. Are you an Iga or a Kouga ninja?" This is a reference to the two main schools of ninjutsu, Iga-ryu and Kōga-ryu, the latter of which Koga himself is named after.
  • Koga's Pokémon Yellow team is of a higher level than his Elite Four team in Gold, Silver, and Crystal and HeartGold and SoulSilver during the first match with him.
  • His Venomoth doesn't appear in games that have Sabrina using a Venomoth in her team.
  • Koga, Bruno, Lance, and Caitlin are the only members of the Elite Four who have appeared in more than one generation (excluding remakes).
    • Koga, Bruno, and Lance are the only members of the Elite Four who have appeared in all the generations prior to Generation V.
  • Koga's updated Sugimori artwork for Pokémon HeartGold and SoulSilver has him in a pose identical to that of his daughter Janine's in her VS artwork, only reversed.
  • Koga is the first Elite Four member who was introduced in an earlier generation and then attained the title in a later generation. The second is Caitlin.
  • Koga's Muk and Koga's Swalot are the only Pokémon used in the Pokémon League who hold anything other than a Berry, holding Black Sludge and Leftovers.
    • He is also the only Elite Four member who has more than one Pokémon holding an item.
  • Koga is the only Gym Leader that does not appear in Black 2 and White 2. This is due to his status as an Elite Four member in the Generation II and IV games.
