Chloe Klick is a supporting character from the anime Genesis of Aquarion. She is the older fraternal twin sister of Kurt Klick. The two siblings share a powerful telepathic bond, which allows them to communicate with each other silently and is most effective between the two of them.

In terms of personality, Chloe is portrayed as earnest, serious, and somewhat reserved. She does not talk to people very much, and her demeanor is described as being similar to that of her brother. Her serious nature often leads her to take on a class representative-like role among the other characters. Despite being considered very beautiful by those around her, she claims that men do not approach her.

Chloe and her brother work as support staff for the organization DEAVA. Rather than being frontline combat pilots, the twins are primarily responsible for controlling and monitoring the computers in the DEAVA control room during battles. On rare occasions, she does participate in combat, piloting a Vector machine in the fifteenth episode.

One of her key relationships is her unspoken romantic feelings for fellow pilot Pierre Vieira. These feelings are hinted at during the series, and toward the end of the story, Pierre comes to reciprocate them. Outside of her connection to Pierre, her most significant relationship is with her twin brother Kurt, who shares her personality and role within DEAVA. Unlike her brother, who prefers dogs, Chloe is said to prefer cats. A notable trait of Chloe's is her insomnia, a condition that ironically proves beneficial when she manages to escape capture by a creature known as the Harvest Beast of dreams, Titania.

Chloe has purple eyes and blue, shoulder-length hair. She is often seen wearing the DEAVA uniform, which consists of a white, collared long-sleeved top with a blue tie, a mid-thigh length skirt, a black belt, blue calf-length socks, and gray shoes. When piloting a Vector, she wears a purple bodysuit with gray wrist guards.
