Blue (Japanese: ブルー Blue) is the third main character of the manga series Pokémon Adventures. Her first Pokémon was a Jigglypuff. As a young child, she was kidnapped by Ho-Oh and raised by the evil Masked Man, where she met and became close with Silver. (This kidnapping led to her ornithophobia, which is not cured until the end of the GSC saga.) The two of them escaped, and Blue went to Kanto, where she stole Professor Oak’s Squirtle.
Blue is quite cunning and quick-witted. She can talk others into believing a bold-faced lie and talk her way out of many tight situations. At one point, she convinces Red to buy a bunch of useless items for his Pikachu. Blue is also a master of disguise, she uses her Ditto as a mask and is able to make herself look like anyone she wants.
Blue’s special skill, as defined by Professor Oak, is evolving; she is known as the “Evolver” (化える者 Evolver). However, until recently she refrained from evolving her Pokémon, because she preferred to lull her opponents into a false sense of security by using unevolved “cute” Pokémon. The special skills of Blue and Silver are homophonous in Japanese.
The original Blue was designed after the early sketches for a Lass and a female protagonist shown in early concept art for Pokémon Red and Green; however, the idea of choosing the character’s gender was unable to be implemented until Pokémon Crystal due to technological limitations of the time. When a female player character from Kanto finally appeared in Pokémon FireRed and LeafGreen, Blue changed her clothes to match Leaf’s in-game appearance.
