Blue
Location: Unknown Dungeon
Information: Blue Oak (Japanese: オーキド・グリーン Green Ōkido) is the second main character of the manga series Pokémon Adventures. He is the grandson of Professor Oak.
Blue debuts in the first round of the manga, A Glimpse of the Glow where he and his rival Red see a Mew in a Pallet Town forest. His first Pokémon was a Scyther -- he is shown with one when he was a child. When he was young, he trained in Johto under Chuck, the Gym Leader of Cianwood City.
Blue's special skill, as described by Professor Oak, is Pokémon training -- that is, leveling them up and making them strong, and as such is referred to as the "Trainer" (Japanese: 育てる者 Trainer).
Blue has a serious, calm, and focused personality in everything he does. Although Red and Blue were once bothered by each other because their personalities are so opposite, they ended up resolving their differences.
Blue and his Scyther were trained by Chuck of Cianwood City when he was a child. Thus, Blue has some cursory knowledge of martial arts, and his Scyther knew Generation II techniques.
Blue also has a rivalry with Koga of Team Rocket. This began when Blue almost killed Koga's Arbok by having his Charmeleon cut it in two, and continued on throughout the series until Koga's reclusion.
