Very few characters have had such an enduring impact upon the landscape of sci-fi and broader popular culture as Spock, so it only stands to reason that this most logical of characters would return time and time again.
A main TOS cast member even as far back as pilot 'The Cage', Spock's Vulcan otherness and fierce intelligence became emblematic of Trek as a whole, and he would go on to appear in every single episode of both the Original and Animated series.
Following the announcement of the series return in TNG, fans would wait another five years before Spock appeared again, attempting to bridge the gaps between Vulcan and Romulus in the two part 'Unification'. A little bit of classic Spock would then be sprinkled into time jumping DS9 episode 'Trials and Tribble-ations', before he rocketed back to the public consciousness in the Abrams films, pulling double duty with Leonard Nimoy and Zachary Quinto each playing the character from different timelines.
With Spock's present and future ultimately told, the appearance of Ethan Peck as a young Spock in Discovery Season 2 would create new depth and intricacy to this character and his childhood on Vulcan, and set the stage for further adventures in both Short Treks and Strange New Worlds.
With a holographic appearance in Prodigy and two picture credits on Lower Decks, there's no other Trek character to this day that better encapsulates the axiom: Live long and prosper.
