Since 2017, the relaunch of Star Trek as a streaming TV empire has produced a huge swath of new characters. From Discovery, to Lower Decks, to Prodigy, and even the first two seasons of Star Trek: Picard, a key feature of most new Trek shows has been new characters, regardless of which time period each show takes place within. That said, Discovery started as a TOS prequel, which gave us new versions of Captain Pike (Anson Mount), Mr. Spock (Ethan Peck), and Number One (Rebecca Romijn).
