You can start from the environment where the story takes place. If it's a story set in a deep, dark swamp, then the monster could be a slime - covered, tentacled beast that blends in with the murky water and uses the fog as cover. Also, think about the monster's purpose. Is it there to guard a treasure? Then it might have a menacing look and be very territorial.
A monster made of pure darkness that seeps into people's dreams and turns their nightmares into reality. It can enter a person's mind while they sleep and manipulate their fears until they drive themselves crazy. In a horror story, the characters would be constantly on edge, not knowing when or if they'll be its next victim.
Sure. There are many ways to use monster girl concepts without involving erotic elements. In a fantasy story, a monster girl might be a misunderstood being who is trying to find her place in a world that fears her. Or she could be a guardian of an ancient forest, protecting it from those who would harm it.
One interesting concept could be the unique designs of the monsters. For example, a monster with the ability to change its form based on the emotions of those around it. Another concept might be the relationships between the original characters (ocs) and the monsters. Sometimes, the ocs have to overcome their fears of the monsters to form an unlikely alliance. Also, the settings in monster oc fanfiction can be really cool, like a post - apocalyptic world where the monsters are the result of some scientific experiment gone wrong.
The concept of Naruto as a'monster' in the fanfiction might bring in unique themes. For example, it could touch on themes of acceptance and self - discovery.

In some science fiction, monster lizards might be alien creatures. They could come from a planet with different environmental conditions that allowed them to evolve into these large and menacing forms. They might be invading Earth for resources or a new habitat.
One interesting concept could be the unique cultural aspects that might be created within the world of the fanfic. For example, how different monster girl species raise their babies, with each having their own traditions and values. Another concept could be the appearance of the baby monster girls. They might have a combination of cute baby features and distinct monster traits like small horns or a tail. Also, the relationships between the baby monster girls and other characters, such as how they interact with human or other non - baby monster characters, can be really fascinating.
Some interesting concepts in everyday monster girl fanfic include the exploration of different habitats. Monster girls might come from magical forests, dark caves or underwater kingdoms. This gives a rich backdrop for the story. Their diets can also be an interesting concept. Some might eat normal food while others could require something more specific like mana - infused fruits. And then there's the concept of their life cycles. Some monster girls might have long lifespans compared to humans, which can create complex emotional relationships when they fall in love with a human who has a much shorter lifespan.
Well, there are fanfic monsters that are based on dark magic experiments gone wrong. Picture a creature made from multiple dark spells fused together, with an unstable form that constantly shifts.
