I, Frankenstein as an adaptation focuses more on the future of The Monster. The Monster is turned into an immortal demon slayer for a group called The Gargoyle Order, graced by the Archangel Michael to protect humans. He is given the name “Adam” and choses to travel on his own. This feels like a reference to the original text, as The Monster had previously spent time in the wilderness, but this adaptation doesn't lean too heavily into that idea. His main villain throughout the film is the demon prince, Naberius, who plans on creating an army of reanimated corpses to kill humanity. A large focus of this film is around protecting Victor Frankenstein’s journal, and the notes he kept on his experiment with The Monster. Adam decides to burn the notes, and after one of the many fight sequences, reclaims his name as Frankenstein.
