Karla Milla-Foden is a character from the anime ID-0, recognized as an employee of the Escavate company. Her primary professional role within the organization is that of information gathering and sales, with a specific focus on intelligence trading. She is described as being sociable and able to make a good impression on others, yet she also possesses a notably stubborn side and is skilled at handling negotiation situations.

In terms of her physical appearance, Karla Milla-Foden is depicted as a blonde woman with short hair who typically wears a formal business suit. She is notable for being one of the only members of the Escavate crew, alongside Captain Grayman, who retains her original human form. She does this by projecting her body as an expanded space avatar, distinguishing her from others who simply transfer their consciousness.

Karla Milla-Foden operates a distinct i-Machine that features a purple color scheme. The design of this machine is noted for particularly emphasizing feminine characteristics, reflecting her identity even when she is not in her human form. Her backstory reveals that she is what is known as an eternal transfer, a person who has lost their original physical body. In her past, she was a powerful and influential capital broker who dominated the cosmic resource market. This former life came to an end following an accident during a drilling operation approximately ten years before the events of the story, which resulted in her body being transmitted away and lost. After this incident, a masked man came into possession of her body and contacted her. In order to secure its return, she was forced into a cooperative arrangement with him, though he does eventually transfer her back to her body as agreed.
