She is voiced by Satomi Arai in the Japanese version of the anime, and by Angela Chase in the English version of the anime.
Bisca is a young woman with long lightt green hair that reaches down to her lower back, a set of long bangs framing her face, and dark purple eyes. She has brownish purple eyes, large breasts, and is always seen wearing red lipstick. After the time skip, Bisca seems to have gained sharper facial features, and has developed a curvier physique. The lower section of her hair is now tied into a thick braid.
Prior to the S-Class Trials of X784, Bisca's attire mirrored that of a fictional cowgirl, with a Western-style hat always visible on her head, a light, polka-dotted neck scarf, and a pair of reddish brown boots. Her body was covered by a short, strapless one-piece dress decorated by spiraling motifs (portrayed as plain blue in the anime) with darker, striped edges (portrayed as plain white in the anime).
During the Miss Fairy Tail Contest, she sported a purple, revealing halter bikini.
After the disappearance of Tenrou Island, her attire became skimpier, consisting of a revealing bikini top covered in dark stripes below an open, dark buttoned vest. A similarly coloured skirt adorned by a series of light strips hanging down from it in the middle part covers her lower body, whilst a pair of high-heeled cowgirl boots decorated by matching strips are on her feet. Also present are a set of armbands now circling Bisca's biceps, paired by darker, simple long bands around her wrists. She also switched to a dark cowgirl hat with a curved-up brim, adorned by a lighter-colored band covered in large studs.
Bisca is a determined woman who loves Fairy Tail and is willing to fight for the good of her comrades. She is very loyal to her guild and will stand up to fight for them, even if she is unable to prevail. She demonstrates a headstrong personality when facing most of her fellow guildmates. However, this headstrong personality of hers completely disappears when it comes to her fellow immigrant from the West - Alzack Connell. Despite the fact that they had always secretly loved each other, they are both too shy to act on their feelings until most of the top Fairy Tail members disappear on Tenrou Island. During the seven year absence, they marry and have a daughter, and are now much more open with their feelings.
