There is no such story in the official Once Upon a Time (OUAT) content. OUAT is a family - friendly fantasy show that focuses on themes like magic, adventure, and character development, not on such inappropriate and unethical topics.
One of the main themes related to Dark Emma was the struggle between light and dark within herself. She was a character who had been corrupted by dark magic, and her journey was about finding a way back to the light. Another theme was her relationships, especially with her family and friends. For example, her bond with Henry was always an important factor in her character arc.
In a fanfiction of Emma's time travel in OUAT, she might accidentally travel to a time when the Evil Queen was just starting to turn dark. Emma could try to befriend Regina and prevent her from becoming the Evil Queen. This would involve a lot of heart - to - heart talks and Emma showing Regina that there is another path. It could also lead to some really interesting interactions with other characters like Snow White and Prince Charming, who might be suspicious of Emma's presence in that time period.
Well, obviously Emma and Hook are main characters as the parents of the baby. Emma, with her strong magic and determination, and Hook with his swashbuckling charm and loyalty. The baby, of course, is also a central figure in the fanfiction, even if it might start as a newborn and grow throughout the story.
A popular type of Emma time travel fanfiction in OUAT could be her traveling to different realms during different time periods. For example, she might end up in Wonderland in the past and have to deal with the Red Queen. This would put her in a whole new set of challenges as she tries to find her way back home. She might also meet some versions of the characters she knows in different forms, which would make for an interesting story as she tries to figure out who is friend or foe.
I'm not aware of any such fanfiction specifically. Fanfiction often varies widely in themes and content, but forced bondage is a rather extreme and often inappropriate theme. Most platforms have rules against promoting non - consensual or overly disturbing content in fanfiction.
One interesting storyline could be the baby having some sort of magical ability inherited from both Emma and Hook. Maybe the baby can control water like Hook and also has Emma's strong will, which helps them in various adventures in Storybrooke.
One common theme is the exploration of family. It shows how family bonds can be formed even after years of separation. Another theme is the idea of identity. Emma has to re - evaluate who she is when she meets her parents. Also, there's often the theme of redemption. Her parents might have made mistakes in the past, and this meeting is a chance for them to make up for it.
The main ethical concern is the non - consensual nature of forced bondage. It promotes a disturbing and unethical scenario that goes against the principles of respect and consent. In fanfiction, characters should be treated with respect, and such themes can be triggering for many readers.
