Who or what is the Whatsitsname in the novel, Frankenstein in Baghdad?

The Whatsitsname is the reanimated corpse that becomes sentient after the soul of Hasib Mohamed Jafaar enters the body that was lying in the courtyard behind the Jewish ruin. The body itself was stitched together out of remains Hadi claimed from the morgue after the car bombing that killed his friend Nahem Abdaki.
