Koga (Adventures)

Koga is a Team Rocket executive working under Giovanni in Pokémon Adventures.

Background
Koga is Fuchsia City's Gym Leader, and he specialises in Poison-type Pokemon and is a veritable expert at ninjutsu. His daughter, Janine, took over the gym in the stead of her father, who became a member of the Johto Elite Four.

Personality
Koga's personality is first depicted to be cruel and merciless, as shown during his battle against Blue and Red in Pokemon Tower, as he uses Articuno to nearly freeze the pair to death. However, after their conflict, Koga returns once more to face off against the Elite Four member Agatha, teaming up with his nemesis, Blue to defeat her, and displays more admirable characteristics such as bravery and concern for others.

Skills
He can use modified Pokeballs, which can be thrown as Shuriken.

Appearance
He has the same look as Koga from the game.His appearance varies throughout the series' medium, in which his first appearance depicted him wearing a bandanna like cloth, except for when he becomes a member of the Johto Elite Four in the HG/SS arc, with his clothing resembling that of his game counterpart's.

Red, Blue and Green Chapter
Koga first appears at Mt. Moon, where he is fervently searching for the Moon Stones to bring back to Team Rocket. He is stopped by an untimely appearance by Red and Misty, who thwart his operation. Koga then makes an appearance at the Pokemon Tower in Lavender Town, planning to use his Gastly to revive the deceased Pokemon corpses stored there. However, Red and Blue form an unlikely alliance against him, but experience difficulty in the battle, primarily due to his Arbok's ability to regenerate and control separated body parts. After this, Koga brings Articuno to Saffron City under Giovanni's orders, who then proceeds to combine the three legendary brids together into an amalgamation of the three. As Red and Blue oppose his plans at Silph Co., he nearly kills them by using Articuno to freeze them to death. However, Blue manages to defeat him by using his Charizard's flames to melt Articuno's ice.

Yellow Chapter
Koga and the other Team Rocket executives team up with the Pokedex Holders, in order to prevent the Elite Four's plans from culminating on Cerise Island. Koga joins forces with Blue, preparing to face off against Elite Four Agatha, which proves to be a perfect match for both opponents. As they face off against each other with their Pokemon, Blue is temporarily paralysed by Haunter's Lick. In response to this, Koga throws a multitude of shuriken at the surrounding area, which Agatha believes to be a fruitless task, and that he is nearing the end. However, Koga reveals that they were Pokeball containing a potent Paralyz Heal, which reached Blue, healing him from the ailment. The two formulate a new plan, with Koga instructing his Golbat to use Leech Life on himself, which results in Agatha's Arbok to not be able to change the pattern on its chest. As Agatha is seemingly defeated by Koga's Confusion, the two proceed to try and navigate their way through the labyrinthine pathways underneath Cerise Island.

However, Agatha was merely manipulating then through her Gengar.

HeartGold and SoulSilver Chapter
He reappears alongside his fellow team-mates several years later, announcing the reformation of the Johto Elite Four.
