Frankenstein's monster was an undead creature that first appeared in the 19th century novel Frankenstein, and later the 1931 film of the same name, and subsequent sequels. In film, the character was portrayed by Boris Karloff.
In 2161, Commander Charles Tucker III had an action figure 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 mom and dad. (ENT: "These Are the Voyages...")
