Lieutenant Tom Nellis was a Starfleet lieutenant who served aboard the survey vessel Antares as first officer and navigator in 2266.

In that year, the Antares transferred a young man, Charles Evans, who had been stranded on the planet Thasus for seventeen years, to the Starship Enterprise, to be transported to Colony 5 where he could be reunited with his closest living relatives. While Charlie was onboard the Antares, however, the crew discovered that he had incredible psychokinetic powers, and could force the crew to do whatever he wanted.

After transferring Charlie to the Enterprise, Antares Captain Ramart attempted to signal them to warn them of the danger that Charlie posed, but Charlie used his powers to remove a warped baffle plate from the Antares's energy pile, causing a warp core breach which destroyed the ship with all hands lost.
