Lisbeth Salander has red hair which she dyes raven black. Upon her first appearance in the series, she is described as "a pale, androgynous young woman who has hair as short as a fuse, and a pierced nose and eyebrows". She has a wasp tattoo, about two centimeters long, on her neck, a tattooed loop around the bicep of her left arm, another loop around her left ankle, a Chinese symbol on her hip, and a rose on her left calf. She has a large tattoo of a dragon on her back that runs from her shoulder, down her spine, and ends on her buttocks. This was changed in the English translation to a small dragon on her left shoulder blade. Salander visits a clinic in Genoa between the first and second books, where she had her wasp tattoo removed as she felt it was "too conspicuous and it made her too easy to remember and identify". She also has a breast enlargement, having previously "been flat-chested, as if she had never reached puberty. She thought [her breasts] had looked ridiculous, and she was always uncomfortable showing herself naked". Salander is a world-class computer hacker. Under the pseudonym "Wasp", she becomes a prominent figure in the international hacker community known as the Hacker Republic (similar to the group Anonymous). She uses her computer skills as a means to earn a living, doing investigative work for Milton Security. She has an eidetic memory and is skillful at concealing her identity; she possesses passports in different names, and disguises herself to travel undetected around Sweden and worldwide. Salander has a complicated relationship with investigative journalist Mikael Blomkvist, which veers back and forth between romance and hostility throughout the series. She also has an on-again/off-again romantic relationship with Miriam "Mimi" Wu.
