Yeah, I had waaaay to much fun on this. So the first is me as a white blood cell, and the second is what I look like after becoming a virus.... I don't know maybe Tuberculosis?..... Giggling, seeing how it affects the lungs and is passed through the air, perhaps Sahara would be an appropriate nickname? I don't know....
After looking at it, I'd say her design and the sand texture on her skin would make sense. Tuberculosis is transferred through the air. The bacteria can stay in the air and remain alive and able to infect for a good several hours. the bacteria more or less eating away at lung tissue, causing holes and pockets, and later on serious bleeding and the classic vomiting up of blood. Tuberculosis is normally associated with lung problems caused by but it can infect the rest of the body, referred to as extrapulmonary TB. That strand is not as infectious as the one strand that attacks the lungs.
Anyway, here is the link if you wanna play [link]
