Shea
Lieutenant Shea was a 23rd century Starfleet operations division security officer who served aboard the  under Captain James T. Kirk. 

Shea was a member of the landing party that encountered the Kelvan Milky Way Expedition on an unidentified class M planet in 2268 on stardate 4657.5. To demonstrate his power to Kirk, Kelvan leader Rojan ordered Hanar to reduce Shea and Yeoman Leslie Thompson into dehydrated porous cuboctahedron  solids, the size of a Human fist, composed of their base minerals which represented the "distilled" essences of their being. Rojan further proceeded to crush and crumble one of the solids, killing that person. To show Kirk that the process could be reversed, he ordered Hanar to reconstitute the still intact solid to reveal that Shea was still alive. Thompson, however, was not so fortunate. 

On stardate 4658.9, Shea was re-neutralized and reduced into a dehydrated porous cuboctahedron solid when the Kelvans considered him one of many non-essential personnel on their trip to the Andromeda Galaxy aboard the hijacked Enterprise. Shea would be reconstituted for the final time after Kirk, Spock, Dr. Leonard McCoy and Lieutenant Commander Montgomery Scott – the only four members of the crew who remained non-neutralized throughout–  regained control of the ship.
