Fortuna (short for Fortunata) the jaguarundi! She was implanted with symbiotic nanobots that give her complete control over her shape and consistency, meaning she's basically a semi-organic T-1000. Her specialty is of course infiltration, since she can near-flawlessly impersonate anybody if she's had the chance to memorise their appearance and mannerisms.

Her 'clothes' are actually her body, shapeshifted to look like clothes for modesty.
