Paine has red eyes, making her look similar to Lulu. With short, silver hair, Paine is most commonly seen wearing her black leather ensemble complete with high-heeled boots, elbow-length gloves and a folded top. She wears a silver pendant threaded with a barbed wire chain. Paine's swords have a skull-like motif at the base of her blade. This motif also appears on the belt buckle of her warrior ensemble, as well as the swords hovering over her head in her special dressphere, Full Throttle. In a bonus cutscene where the girls spend some time in a hot spring in Mt. Gagazet, Paine wears a black and white bandeau bikini swimsuit with additional wrist, ankle and neck bands.
Paine's swords are unique in her Warrior, Dark Knight, and Samurai dresspheres, while in her White Mage and Black Mage dresspheres she wields the Malleable Staff and Enchanted Rod respectively. In the Gunner dressphere, she wields Yuna's Tiny Bee pistols and wields a purple variant of Rikku's dagger blades while in the Thief dressphere. Her deck theme for the Lady Luck dressphere is diamonds and her Mascot dressphere is a Tonberry. All of her footwear is high-heeled. When applicable, Paine's dressphere outfits incorporate boyish designs; e.g. her Psychic outfit is based on a typical Japanese schoolboy uniform.
Paine's personality resembles Auron's in the way she reveals information only when she needs to. Not much is known about Paine except that she is cynical, rather quiet, and generally keeps to herself. Paine is tough and loves a good fight, but she is also sensible enough to smell trouble a mile away. If she feels her fellow Gullwings are getting too enthusiastic, she uses sarcastic cracks to jolt them to their senses, and despite Rikku's constant prying, she refuses to divulge any information about herself, except that she has always wanted to fly on an airship and hunt for spheres containing records of Spira's past.
In spite of her dry wit and demeanor, Paine values her friendship with Yuna and Rikku, but only after spending three months traveling Spira by herself, that she is able to express these feelings towards them. Her physical mannerisms are somewhat boyish, perhaps a side effect from her past adventures with Nooj, Gippal, and Baralai.
