The Bride Of Frankenstein is also known as the Monster's mate.
In Mary Shelley's Frankenstein or the Modern Prometheus, Victor Frankenstein is tempted by his monster's proposal to create a female creature so that the monster can have a wife: “Shall each man,” cried he, “find a wife for his bosom, and each beast have his mate, and I be alone?" The monster promises that if Victor grants his request, he and his mate will vanish into the wilderness of South America, never to reappear. Fearing for his family, Victor reluctantly agrees and travels to the Orkney Islands to begin his work on the creature's mate. He is plagued by premonitions of what his work might wreak, particularly the idea that creating a bride for the monster might lead to the breeding of an entire race of creatures that could plague mankind. He destroys the unfinished bride after he sees his first creation looking through the window. The monster witnesses this and vows to be with Victor on his upcoming wedding night. True to his word, the monster murders Frankenstein's new wife Elizabeth.
