Blair is a Gym Leader in Pokemon Genesis. She uses the Fire-Type and gives out the Conflagration Badge to those who defeat her.
Blair, as a child, suffered a very bad experience while being stuck in the snow for several hours, nearly freezing to death. She now is afraid of anything cold and often stays inside, huddled in a corner, during the winter. To protect herself from the cold she surrounds herself with Fire-Type Pokemon. It has been revealed that her favorite Pokemon is Chimchar.
In The Game
Blair has a fiery nature and dislikes losing. After considering throwing Jackal/Panther out of the gym, she reconsiders and decides to give the Badge, HM and teach one of Jackal/Panther's Pokemon Fire Punch. Once you defeat Zack, you catch her looking into the window of the gym. If you promise not to tell anyone, she gives you TM35 (Flamethrower).
