Field doctor. His work is to help the wounded and the dying on the battlefield. Through the use of special medicine he can even bring the dead back to life, if they didn't suffer heavy functional damage. Moonlights as a "deplanter", extracting valuable implants and symbiotes (and organs, if needed) from the dead for reuse. For transporting those, there are special containers on his back with liquid nitrogen cooling. Due to body structure, the lines from the filter of his gas mask are connected directly to the nasal sinuses. Burdened by great life experience, he is a battlefield butcher, stern and taciturn.
This my sick imagination ^^`
This draw is be inspired from what story?
