Martel has short orange hair, a green right eye, a blue left eye, and fair skin. She has a scar over her face, going from her left cheek to the right side of her forehead.
Martel wears a white short-sleeved shirt with a green skirt, green knee socks and black shoes. She also wears a black gas mask and blue rubber gloves.
She is first encountered in the Tower, after Evan O'Neill obtains the Shining Sun. She mentions a strange guy in a green labcoat starting a chemical war in another continent, of which she was the sole survivor.
Martel makes a few appearances.
- "Martel Aar" sounds a lot like the Dutch word "martelaar", meaning "torturer". This is actually a coincidence.
