Kim Sanchez is a nurse/prosthetist in the hospital on Basement Level 4 of the Corona Tower research center.

Kim normally wears large earrings, often in a hoop style. Kim gets along well with others, but her very thin frame and perennially stringy blonde hair are a challenge to her self image.

To compensate for her self image, Kim chews and pops gum constantly. She had her fingers tattooed as a young woman (all ten!) after the unexpected deaths of her three cats. The tattoos spell out her cats' names. 

Kim realizes she might have an eating disorder and vows to gain ten pounds. She never does.

We first meet Kim in Book 4 of The Human-Hybrid Project, Reflections of the Silverback.
