Humanoid amphibian, expert at genetics and advanced body modification (the sort that involves computer-controlled cylinders of green goo), spacefaring mercenary doctor, and somewhat of a hedonist - Neena Henshall is one of my oldest characters, but she's evolved quite a bit since her initial conception. The extra limbs are her own work (she was originally a standard humanoid), which she'll happily install on anyone who pays enough. When she's not working and in need of protective gear, she wanders around naked just like this - there's nothing she feels needs hiding, and her body is basically genderless anyway. It also helps when she goes for a swim; no need for a bathing suit when her skin is enough, and the gills she embedded in her neck let her stay submerged as long as she feels like it.
