Star Trek: Every First Officer Ranked
5. Number One (Una) - Star Trek Discovery
With the small amount of screen time she has (so far) received, Number One has made quite the impact on Star Trek Discovery. She has already been shown to be a great friend of Captain Pike but, thanks to the Short Trek Q & A, she has also been shown to be a great mentor to Spock as well.
In this modern, fast paced Star Trek, character building can sometimes be lost to spectacle. Discovery has dazzled with its big budget CGI and, occasionally, has rang hollow because of it. Not so with Una. Stepping into the shoes of Majel Barrett (albeit half a century later) carries weight in the Star Trek family and her Number One is a very different creature.
But she is a strong and competent creation, easily taking control of each situation she is thrust into. To see her develop even further on a spin off show would be fantastic but if the last we saw of Number One was her smile as the Enterprise warped away into new adventures, then we have seen a brilliant first officer to a brilliant captain, all in the course of a few short episodes.
