You were iconic and important for a number of reasons, inspired by Martin Luther King Jr. to remain a steadfast part of the Enterprise crew, but it wasn't only in Gene Roddenberry's original "Wagon Train to the Stars" where you shined.
There's Unbelievable!!!!! (a spacey parody); The Adventures of Captain Zoom (another such parody); Surge of Power; Tarzan's Deadly Silence; Surge of Dawn; Truck Turner (you really went against type in that one!); Lady Magdalene's; Made in Paris; Tru Love; Doctor, You've Got to Be Kidding!; Are We There Yet?; American Nightmares; Sharknado 5; This Bitter Earth; The White Orchid; Renegades; Snow Dogs; and the zombie-encrusted The Supernaturals. (Incidentally, you were also one heck of a sweet singer.)
But of course, it all comes back to Nyota Uhura, who not only made the three-year run of Star Trek so classic, but the Saturday-morning, animated series and those blockbuster, big-screen movies (I-VI), as well as the indie-produced, Star Trek: Of Gods and Men, Nickelodeon's animated Star Trek: Prodigy, and last but not least, Woman in Motion, a bio/documentary that details your impact as the legendary communications officer upon popular culture and the world.
You meant a lot to a lot of people, and to your fans you were royalty. In fact, your status will likely shine ever brighter as the decades pass. That's the way of legends, and you, Ms. Nichols, are indisputably one.
