When it comes to Star Trek, there is arguably no character more associated with the franchise than Spock. The Vulcan First Officer became the breakout character of the series and remained a fixture in pop culture. He is one of the few characters to make it past the original pilot for the series and then be a major character on not just Star Trek: The Original Series but original actor Leonard Nimoy returned to play a role in all six live-action films, two episodes of Star Trek: The Next Generation and the two J.J. Abrams-directed reboots where he passed the baton on to actor Zachary Quinto. In addition, actor Ethan Peck plays a young Spock on both Star Trek: Discovery and Star Trek: Strange New Worlds, making him the character to appear in the most entries in the franchise.
