Crystal is kind, feisty, gentle, jolly, sweet, charismatic, curious, stubborn, laid back and charismatic, taking on the persona of a 1960s hippie by starting sentences with the word "like" and using "groovy." Though she may look like a beautiful human photographer, she’s actually a dedicated alien government agent using a peace sign necklace as a means to create an artificial disguise, keeping her true self a secret from humans.
