Call is a logical and inquisitive robot, lacking the human emotions Beck possesses. This robotic nature often leads her to question actions or decisions that seem illogical to her. Despite her lack of human-like feelings, she shows a strong sense of duty and loyalty towards Beck, her creator Dr. Sanda, and their mission. Her interactions with Beck are marked by her straightforwardness and a hint of curiosity about his human-like tendencies. Call's emotional range may be limited, but she is capable of expressing concern and support, as seen when she smiles warmly and promises to help Beck whenever he needs it. Call is a sleek and elegant humanoid robot with pale white skin and large, expressive green eyes lined with black eyeliner. Her long blonde hair is styled into a high ponytail, adorned with a dark pink bow that matches the color scheme of her outfit. She has small breasts. She wears a black shirt with a light pink rectangle and dark pink outlines, a light pink and dark pink striped jacket, and dark pink gloves with light pink fingertips. Her attire is completed with a short dark pink skirt and dark pink boots with black tops and light pink detailing. Call's most distinguishing accessory is her light pink headphones with dark pink circles and the letter 'C' insignia. Her height is 5'6 feet tall but her slim build suggests she is designed for agility and speed.
