Pikeone

"Number One is very resourceful. People have a tendency to end up owing her favors."

- Pike about Una.

Pikeone is the het ship between Christopher Pike and Number One (Una) from the Star Trek fandom.

The Original Series
In "The Cage", Pike and Number One are one of the first characters introduced. Number One is the first officer of the Enterprise (that is the reason behind her nickname), and she is shown as a logical, calm and professional woman. Pike completely trusts her, and leaves the ship in her care without hesitation. It is hinted at the very beginning that despite her cold attitude, Number One has feelings for Pike - when, after losing his Yeoman, he says about Colt that "He is not used to having a woman on the bridge", and mentions that Number One doesn't count, because she is "different", she is obviously hurt.

During the Cage, her feelings become confirmed, when the Talosians kidnap Pike and two women from the ship, Number One, and Yeoman Colt. However, unlike Colt, she keeps up a professional attitude, and overloads a phaser, forcing the Talosians to either let them go, or die with them. Later she even scolds the Yeoman when she asks the captain, "who would have been Eve", if they had to stay on the planet.

Short Treks
Even though they have few scenes together, the couple is further hinted in the Short Trek episodes, when Number One gets stuck in a turbolift with Spock, and he mentions that she seem to notice a lot about the Captain. Number One doesn't answer, just asks the engineering if they could hurry. However, she talks about Pike with great respect and appreciation.

Discovery
In Discovery, Number One is mostly on the Enterprise, only appearing meeting Pike on some occasions, and in the finale. However Pike often talks about her, mentions that she is "very resourceful", and it is shown that he has great respect and trust towards his first officer as well. They joke a lot together, and Pike is the first and only person in the series, who calls her on her first name without receiving any negative comments.

Fanon
Pike and Number One is a quite popular ship in the fandom. It's the most written het ship for both characters, and the most written ship for Number One. The canonical pairing, Pike/Vina could be considered its main rival, however it's not really that popular despite its canon status.

Trivia

 * They are played by different actors in The Original Series and Discovery. In the Original Series, Pike is portrayed by Jeffrey Hunter, and Number One by Majel Barrett, while in Discovery, he is played by Anson Mount and she by Rebecca Romijn.
 * It is a possibility that this relationship could have become fully canon at some point, since Pike and Una's friendship is one of the most important relationships in "The Cage". However, after the main crew of the series changed to Kirk's Enterprise, "The Menagerie" episodes reused the material from the pilot and showed a future where Pike got seriously injured, paralized, and in the end, returned to Talos and Vina. From then on, even though Number One's feelings is further hinted in Discovery, Pike is shown deeply in love with Vina, never showing more than friendship towards her.
