Private Dobbs

Private Dobbs, First Class, is a US soldier the Chosen One can find in the Sierra Army Depot, cryogenically preserved since who-knows-when. He was killed in battle and pronounced dead, but was able to learn this via an out-of-body experience. His body was then taken to a laboratory and immersed in biomed gel in an attempt to regenerate and revive the erstwhile private.

The procedure was evidently a success. When defrosted, he is disoriented but in good health, aside from a headache. However, a few seconds after setting off to rejoin his unit, he experiences Post-Cryogenic Syndrome and disintegrates into a puddle of slime.
