|First Appearance||Titan's Sleeping Warrior|
Claire Crystal (Kurisutaru Kurea) is a waitress aboard the GE999.
Claire is a machine person with a body made of transparent glass, which she was pressured into adopting by her vain and shallow mother. She bitterly regrets having been mechanized and hopes to earn enough money with her waitress job to have herself restored to her original human body, which is being held in cryogenic suspension on Pluto.
In the TV series Claire dies when she detonates her own power cell to destroy a physical hallucination that was trying to pull Tetsuro off the train. In the movie she is killed while protecting him from Queen Prometheum.
