Captain Pike In Command of The Enterprise
https://en.wikipedia.org/wiki/Christopher_Pike_(Star_Trek)
Christopher Pike is a fictional character in the Star Trek science fiction franchise. He is the immediate predecessor to James T. Kirk as captain of the starship USS Enterprise.
Pike is the second captain of the USS Enterprise NCC-1701 and the first to be shown in Star Trek canon. Star Trek: The Animated Series reveals that Captain Robert April predated Pike, and printed Star Trek fiction and reference books also identify April as Pike's predecessor.[4][5] Pike took command of the USS Enterprise in the year 2250, at the age of 38, taking over command from Robert April, who commanded the Enterprise for five years.
Pike first appeared as the main character of the original unaired pilot episode for Star Trek: The Original Series, "The Cage", portrayed by Jeffrey Hunter. When this pilot was rejected, Hunter withdrew from the series, and the character of Pike was replaced with Kirk. The series later established Pike as being Kirk's predecessor in the two-part story "The Menagerie", which extensively used archive footage from "The Cage"; the framing story included an older, scarred, and disabled Fleet Captain Pike portrayed by Sean Kenney.
The films Star Trek (2009) and Star Trek Into Darkness (2013), which take place in an alternate timeline, feature Bruce Greenwood as a version of Pike who acts as a mentor to the young Kirk. Christopher Pike is a main character in the second season of Star Trek: Discovery (broadcast 2019), portrayed by Anson Mount; set several years after "The Cage", the show has Captain Pike assume temporary command of the USS Discovery. The series Star Trek: Strange New Worlds (2022), a spinoff of Discovery, is centered on Pike's time as captain of the USS Enterprise, with Mount reprising the role.
