Margles is a Martian woman who was once Magic Man's wife. As revealed in "You Forgot Your Floaties," she was one day taken away by the powerful deity GOLB, which encouraged Magic Man to create a defense system in her image. However, this defense system ultimately failed, causing her to fall off Olympus Mons, a Martian volcano, which Abe Lincoln mentions was the beginning of Magic Man's jerky attitude.
Margles is a green Martian woman with medium length brown hair. She wears a purple dress and brown knee-high boots. She is also visibly shorter than Magic Man in the photo, though she may be sitting or leaning as she is giving Magic Man a hug in this photo.
