From: Star Trek: The Next Generation
Caption: Gomtuu, also known as "Tin Man"
Origin: space. The last of a unique alien species of living vessels which survived symbiotically with its crew. Apparently, the alien communicated telepathically. Gomtuu (also called "Tin Man"), the last of its kind and extremely lonely, chose to orbit a star which was about to go supernova (stardate 43779.3). That is, until the depressed Gomtuu found the Betazoid super-telepath, Tam Elbrun, which offered both lonely individuals an ideal relationship.
