 SPOILER: In the original version of this story, "In Thy Image",  Captain Dylan Hunt goes up into space to confront a probe that has  been enhanced by an alien civilization. When the probe realizes that  Dylan is a member of NASA, the group that created it, it shuts down,  having received its answers. This basic premise was retained for the  finished film, with the exception that in ST:TMP, Commander Decker  merges with VGer when he gives the probe the signal, and VGer  transforms into a higher state rather than shuts down. "Dylan Hunt"  never became part of the Star Trek universe, but later got his own  as captain of the Andromeda Ascendant in Gene Roddenberrys  Andromeda.
