A crewmember aboard the NCC-1701, Tyler served as the ship's navigator under Captain Pike. In 2254 he was a member of the landing party which beamed down to Talos IV and was nearby when the Talosians abducted Captain Pike. Tyler and Spock attempted to blast their way into the Talosian's underground complex to rescue the Captain, but without success. He later suggested an even more powerful assault which also failed.
