Blue (English: Green; Japanese: ブルー) is the third main character of the manga series Pokémon Special. Her first Pokémon was a Jigglypuff. As a young child, she was kidnapped by Ho-Oh and raised by the evil Mask of Ice, 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 Pokémon evolution (化える者), although until recently she refrained from evolving her Pokémon, because she prefered 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.
Blue first met Red and tried to scam him out of his money by selling fake items. Red hunts her down to reclaim his money, but she uses this opportunity to steal his badges. Then Red learns that her Squirtle was stolen from Professor Oak.
Later, she reveals that she was kidnapped by Ho-Oh as a child, and was in fact originally from Pallet Town. She has ornithophobia and is afraid of Flying-type Pokémon because of this.
Blue eventually ends up as rival to Sabrina, and helps Red and Green defeat the Elite 4.
Afterwards, she manages to get into the 9th Pokémon League tournament without badges by making it through special qualifying elimination rounds. Blue makes it to fourth place, but is defeated by Professor Oak, who uses her fear of birds against her by using a team of Flying-type Pokémon to defeat her. She confesses to Professor Oak who forgives her for stealing Squirtle and gives her the last Pokédex.
Blue trains Yellow and gives Yellow her boy disguise, and sends her off to save Red. She believes the Elite Four were controlling Ho-oh, so carries a grudge against them. However, she eventually learns she was wrong and resolves to return to Johto.
Blue reappears late in the storyline, when her relationship with Silver is disclosed. She and Silver escaped from the Mask of Ice, who used Ho-oh and Lugia to kidnap her along with Will, Shum, Karen, and Kart to be his servants. Blue confronts Ho-oh and finally overcomes her ornithophobia, and uses the Legendary Birds to help defeat the Mask of Ice.
FireRed and LeafGreen Saga
Blue finally learns that her parents have moved to the Sevii Islands and resolves to reunite with them. Before she can, both they and Professor Oak are kidnapped by Deoxys. Here, her Pokémon finally evolve to their final stages and her Blastoise learns Hydro Cannon. At the end of this saga, she was turned to stone along with 4 other Pokédex holders.
Most of Blue's Pokémon nicknames, with the exception of Puriri, contain syllables from the species' Japanese name, followed by a Japanese honorific. "Puriri" comes from Jigglypuff's Japanese name, Purin.
