She was first mentioned by Nefertari Vivi, who explained how Baroque Works was organized to the Straw Hat Pirates. Neither her nor her partner are seen in the series, but there is a concept art of her.
She wears a hood with three antennae-like stalks coming out of it. The front of the hood is designed to resemble an animal. She has on long pants and a short sleeved shirt with a scarf. She carries what appears to be an unsheathed sword.
Nothing is known about Miss Tuesday's personality.
