A blast from the past here, Star Trek: The Motion Picture figures made by Mego. They were obviously hoping to reproduce the success of the Star Wars action figures but failed.
From left to right we have: Admiral Kirk, Commander Decker, Mr Spock, Scotty, Dr McCoy, Ilia, Arcturian, Megarite (missing cloak), Zaranite and a Klingon.
The only two figures I’m missing are the Rigellian and Betelgeusian, both of which are very rare and thus expensive. Note that Mego did not get around to producing Chekov, Sulu or Uhura figures. Presumably these would have come later had the range been successful. It should also be noted that the species names of some of the alien figures were mixed up.
