The Original Series of Star Trek first aired in 1966 and ran for three seasons. The cult phenomenon went on to spawn an animated series, then further live action shows following different Star Fleet crews in The Next Generation, Deep Space Nine, Voyager and Enterprise.
Still going strong today, with Discovery, Picard and the animated series Lower Decks currently airing, even before you consider the thirteen films and several other projects still in production, this adds up to several hundred characters to keep track of.
