I found two novels that fit the requirements. The first book was " Mechanical Godzilla: Born to be a Great Villain." The main character was a mechanical Godzilla who was an enemy of humans. This novel was also labeled as Invincible Evolution and Infinite Evolution. It was filled with intense battles and thrilling plots. The second book was " Redemption of Non-Human Villains [Quick Wear]". The main character was a person who was bound to the redemption system. His mission was to redeem those villains who had turned evil, and these villains were all cruel and terrifying non-humans. These novels all meet your requirements for villains who are not human. I hope you will like them.
