The Shadow Thief possesses a Dimensiometer, a device which transports his physical body to the other-dimensional world of Xarapon. His shadow remains, which is untouchable by physical means. However, he wears special gloves which allow him to touch things in the Earth dimension. His shadow form has the following powers:

A common burglar, Carl Sands was apprehended when a policeman saw the "well-hidden" criminal's shadow. During his long stay in prison, Sands felt mocked by his shadow, for it could leave his cell, but he couldn't. After he had served his time, Sands vowed to use his shadow the way he had imagined he could while a prisoner. He studied shadow facts and legends and even performed "experiments" based on this "research."
Sands accidentally managed to open up a portal to the dimensional world of Xarapon and then saved the life of Thar Dan, a scientist there. Sands was rewarded with the Dimensiometer, a device that enabled him to shift his body to Xarapon and appear on Earth only as an intangible shadow. Nothing could touch Sands, yet he could steal at will with the aid of special ebony gloves. The only drawback to this wondrous device was that every time Sands used it, it affected the magnetic lines of Earth. Too-frequent usage could cause another Ice Age, a dire possibility that never troubled Sands overmuch as he began his new career as the Shadow-Thief.
