Frankenstein's monster is an undead creature that first appeared in the 19th century novel and later the 1931 film Frankenstein, and subsequent sequels. In film, the character was portrayed by Boris Karloff.
In 2161, Commander Charles Tucker III had a model of Frankentein's monster in his quarters aboard the NX-class starship Enterprise. When Tucker died, Commander T'Pol packed the figure in a suitcase that she gave to his parents. (ENT: "These Are the Voyages...")
