"Star Trek" has been around longer than some of us have been alive. Despite multiple breaks and various spin-offs, movies, cartoons, and reboots, the multi-franchise show has never truly stopped being a fan favorite. One of the main contributors to the show's longevity and success are the many characters from different universes and cultures. By "going where no man has gone before," "Star Trek" introduced many characters for us to fall in love with. While these characters have been immortalized over the years, the actors playing them unfortunately came to the end of their very mortal lives. Here we honor the "Star Trek" actors you forgot passed away.
