Nix

Nix (also known as Pluto II) is a female natural satellite of Pluto.

Her celestial counterpart, along with Hydra, was discovered in 2005. It is the third of Pluto‘s moons, both by size and distance.

Personality
Nix is somewhat pessimistic, dramatic, and argumentative. She often gets into fights with Namaka, but never explains why. Nix is occasionally helpful, trying to be a supportive sister to Charon and helping out Hydra.
