One common element is the dangerous situation the girl is in. It could be anything from being held hostage to being in a life - threatening natural disaster. Another is the heroic entrance of the soldier, all brave and ready to save the day. And often, there's some sort of connection or relationship that develops between them after the save.
In a 'soldier saves girl' fanfic, it might be that the girl is in a natural disaster zone. The soldier, with his training and sense of duty, comes to her rescue. He might carry her to safety through floods or help her out of a collapsed building. This event could be the start of an interesting adventure for both of them as they face the aftermath together.
It could be an unknown girl from a random village that Naruto just happens to pass by and save from a natural disaster, like a flood or a landslide. Naruto's quick reflexes and strength would allow him to rescue her.
She could be a long - lost relative of one of Dean's friends. For example, she might be related to Bobby Singer. She has grown up hearing stories about Dean and when she finally meets him in danger, she uses her family - taught skills to save him.
Well, 'elf girl' might refer to a girl with elven characteristics in a fictional context. 'Saves' is straightforward here. And 'fanfic' is short for fan fiction. So perhaps it's about a story where this elf - girl is the hero who safeguards a fan - created story. It could be from some sort of attack by a character who doesn't like fanfic, or from a natural disaster within the fictional world of the fanfic.
Well, perhaps the girl is a hunter too. She meets Dean in a really dangerous situation, like when he's being attacked by a powerful demon. She uses her unique skills, maybe some kind of magic she has been hiding, to save him. And from that moment on, Dean starts to see her in a different light, and a love story begins.
A cool concept could be a monster girl soldier from a different dimension who gets stranded in a world at war. She has to adapt to this new world's military strategies while also trying to find a way back home. Her alien - like monster features, such as tentacles for extra - strong grips, give her an edge in battle.
Sure. In a fanfic world based on a popular fantasy series, there's a fan - written story that holds the key to restoring peace in the land. However, an evil wizard wants to destroy all fanfics because he believes they distort the original magic. An elf girl, who loves the creativity of fanfics, discovers the wizard's plan. She uses her elven speed and stealth to steal the wizard's magic staff, which he was going to use to burn all the fanfics. By doing so, she saves the fanfic.
First, define their monster traits clearly. If it's a mermaid - monster girl soldier, her ability to swim and communicate with sea creatures is important. Then, give them a backstory. Maybe she was a mermaid princess who decided to become a soldier to protect her underwater kingdom from land - based threats.
