Everyone knows Spock (Leonard Nimoy) as probably the most influential character in science fiction. Whenever you mention the genre to people who aren't that familiar with it, everyone tends to know at least the Vulcan salute or "Live long and prosper." As iconic as those are, however, they are far from being the finest our favorite half-Vulcan has to offer. With so much of him on Star Trek, from The Original Series to the movies, it might seem difficult to pinpoint Spock's best moment, but look no further than Star Trek II: The Wrath of Khan and his iconic line: "The needs of the many outweigh the needs of the few." It captures his essence perfectly, and is definitely among pop culture's most misquoted and misunderstood lines.

Next year, Star Trek will have been on the air for sixty years. Fourteen movies and almost a thousand TV episodes later, the franchise can still look back to the very first episode that was ever aired, "The Man Trap," for inspiration. Its blend of science fiction, horror, action, and thoughtful introspection set the show on the past that it would ultimately follow for six decades. It all started with the death of one character who was never really seen on-screen: Nancy Crater.
