Nix is a boss in Final Fantasy XIII. She is half of Snow Villiers's Eidolon, and she is fought in Lake Bresha, along with Stiria, by Snow, as a test to prove his strength to them. They first appear when Snow is threatened by oncoming PSICOM troops, and save him from them, before the Eidolon turns on Snow. Along with Stiria, they make up the Shiva Sisters. Once the Shiva Sisters have been defeated, they enter Gestalt Mode, and become what appears to be a motorcycle.
Nix is possibly the easiest Eidolon to fight. During the battle, Stiria will heal Snow and cannot be targeted. Nix will attack physically. The best way to win their acceptance is to queue up Steelguard and use it just as Nix attacks to build their Gestalt meter. If Steelguard is active as she hits, the meter will build.
