An alternate ending could be that the Huntsman sacrifices himself to save Snow White. He could step in front of a fatal blow meant for her, and in his dying moments, Snow White realizes just how much he means to her. This would be a tragic yet powerful ending, showing the depth of their connection.
If there was a lemon fanfiction of 'Snow White and the Huntsman', it might take the form of a re - imagining of their story with a stronger focus on their physical and emotional attraction. It could be a story that dives deeper into the unspoken tension between them. Instead of just the typical adventure and power struggle against the Evil Queen, their relationship could be at the forefront, with new situations and challenges arising from their budding and perhaps more 'spicy' connection.
First, it's important to note that if by 'lemon' you mean something with adult or inappropriate content, that's not advisable as it goes against many ethical and community standards. But if you mean a more 'flavorful' and unique take on the relationship between Snow White and the Huntsman, start with a deep understanding of their characters from the original story. Think about what could have been different in their interactions. For example, you could add more scenes of them alone, talking about their hopes and fears which could lead to a deeper emotional bond.
One interesting aspect in Snow White and the Huntsman fanfiction exploring the darker side could be delving deeper into Ravenna's backstory. Maybe she had a tragic past that led her to become so power - hungry. For example, she could have been wronged by someone in her youth, which made her believe that only absolute power could protect her. This would add more layers to her character and make her more than just a one - dimensional villain.
The OC could be a fellow captive of the Mirror's evil plans. In this case, they would bond over their shared experience of being targeted by the Mirror. They could support each other, with the OC using her unique abilities to help Snow White escape from the Mirror's clutches. For example, if the OC has the power of invisibility, she could use it to spy on the Mirror and gather information to help Snow White.
One main theme is the battle between good and evil. Snow White represents good, while the evil queen is the antagonist. Another theme could be self - discovery. As Snow White embarks on her journey, she discovers her own strength and power.
The story mainly focuses on Snow White's journey. In the first part with the Huntsman, she escapes from the queen's evil plot. The Huntsman helps her find her way. As for the 'Winter War' aspect, it could imply a fight against the forces of evil during winter. Maybe it shows how Snow White and her allies have to endure the harsh winter conditions while fighting against the queen's minions to regain her rightful place in the kingdom.
Snow White herself is very interesting. She is not just a damsel in distress but a strong - willed character. The Huntsman is also cool. His internal conflict between following the queen's orders and doing what's right makes him engaging.
One idea could be that the Huntsman is from a different realm in the fanfiction. He has unique powers from that realm which he uses to protect Snow White in new and unexpected ways. For example, he can communicate with magical creatures that are native to his home realm and they help him in battles against the Evil Queen.
