Companion
History:
(Voice of Elizabeth Rogers). Cloudlike life-form that lived on a planetoid in the Gamma Canaris
region. In 2117, the Companion discovered aged scientist Zefram Cochrane drifting in space, near death. The Companion brought
Cochrane to her planetoid and cared for him, rejuvenating his body, giving him effective immortality, but subjecting him to extreme
loneliness. Over time, the Companion grew to love Cochrane. In 2267, the Companion abducted Kirk, Spock, McCoy, and Federation
Commissioner Nancy Hedford from the Enterprise shuttlecraft Galileo to livewith Sakuro's disease, agreed to merge with the
Companion, becoming a single, human individual. The resulting individual, still in love with Cochrane, remained with Cochrane on
the planetoid for the rest of a normal human lifetime.
TOS "Metamorphosis"
The Federation remained
unaware of Cochrane's fate and of the existence of the Companion because of Kirk's promise to Cochrane. The Companion was designed
by future Star Wars Oscar-winner Richard Edlund at Westheimer photographic effects company.
