Pounamu is a pilot from Gem Homeworld. As one of Yellow Diamond's senior pilots, she is a respected gem between her peers. She and her team is starting a colony by the means of organic reproduction in an unnamed distant planet.
While Pounamu is generally calm and reserved, with her closest friends, she can be pretty noisy. Outside of her comfort zone, however, Pounamu can be seen as ruthless, strict, and intelligent. She is a senior pilot, which means she is very knowledgeable of mechanical stuff. She is also very intricate and compulsive obssessive. Pounamu is also regarded as a decent leader, although sometimes she can be very manipulative and controlling.
