The Mummy is a citzen of Halloween Town. Being fully wrapped in white cloth, the only visible part of him is one eyeball. He is friend with the Corpse Kid and The Winged Demon.
It is possible that he is a cyclops mummy, due to he having only one eye. The vampire may have checked behind his eye when looking for Jack, " I peeked behind the cyclops eye. I did! But he wasn't there."
He has also been shown as being something of an assistant to the Mayor, sounding the alarm when Jack goes missing and other such duties.
