What is the name of the monster in Mary Shelley's book, Frankenstein?

Frankenstein's monster, sometimes known as Frankenstein, is a fictional character whose fictional creator was Victor Frankenstein. The monster first appeared, without any name, in Mary Shelley's 1818 novel Frankenstein; or, The Modern Prometheus. Shelley's title thus compares Victor Frankenstein to the mythological character Prometheus who fashioned humans out of clay and gave them fire. Although nameless in Shelley's novel, the creature took on the name "Frankenstein" in later years.

In Shelley's Gothic story, Victor Frankenstein builds the creature in his laboratory through an ambiguous method consisting of chemistry and alchemy. Shelley describes the monster as 8-foot-tall (2.4 m), hideously ugly, but sensitive and emotional. The monster attempts to fit into human society, but is shunned, which leads him to seek revenge against his creator. The monster occupies "a border territory between the characteristics that typically define protagonists and antagonists"
