A typical theme is the mystery surrounding the sirens. Since sirens are often depicted as somewhat otherworldly beings in fanfiction, there's a sense of mystery about their origin, their true capabilities, and their place in the 'Once Upon a Time' universe. This mystery adds an element of intrigue to the stories. Also, redemption is a theme that can be found. A siren who has caused harm in the past may try to redeem themselves through their relationship with a character from the show.
Emma Swan could also be a popular choice. She's a strong - willed and powerful character. The contrast between her strength and the siren's seductive power can create some really engaging storylines. Plus, Emma has her own insecurities and past traumas that a siren could either exploit or help her overcome, depending on the direction of the fanfiction.
One common theme is the exploration of alternate timelines. Since 'twice upon a time' implies a doubling of the story - perhaps one that already exists in the 'once upon a time' framework - fanfiction often delves into how different choices in these two timelines can lead to vastly different outcomes for the characters. Another theme could be the redemption of characters. In these types of fanfictions, characters who might have been villains in the original 'once upon a time' setup could get a second chance in the 'twice upon a time' scenario to change their ways and become heroes or at least more morally ambiguous figures. Also, the theme of lost love and its rekindling is popular. Maybe a couple was separated in the 'once upon a time' but are reunited or have a chance at a new relationship in the 'twice upon a time'.
One common theme is redemption. Many fanfictions focus on characters like Regina or Rumpelstiltskin trying to atone for their past wrongs. Another theme is alternate universes. Writers like to explore what would happen if the characters were in different situations or worlds. Love is also a big theme, whether it's romantic love between characters like Emma and Hook or the love between family members like Snow White and her father.
One common theme is love and relationships. Since the show has a lot of complex character relationships, fanfiction often explores different aspects of love between characters like true love's kiss and forbidden love. Another theme is redemption. Many characters in the show have a dark past, and fanfiction might focus on their journey towards redemption.
Family relationships are a big theme. Some fanfics focus on the family dynamics between characters like the Charmings and their descendants. There are also fanfictions that revolve around the theme of identity. Characters in 'Once upon a time' often have complex identities, and fan writers like to dig deeper into how these identities are formed and how they can change over time.
One common theme is adventure. Since Peter Pan is all about adventures in Neverland, the fanfictions often include the reader joining Peter on his wild escapades, like fighting pirates or exploring hidden parts of the island. Another theme is the concept of eternal youth. The reader might experience the allure and consequences of never growing old in the story. Also, themes of friendship and first love are quite prevalent as the relationship between the reader and Peter Pan develops in these fictional tales.
One common theme is time -travel. Since both shows deal with different timelines in some way, fanfictions often explore more about time -travel and how it affects the characters. For example, a character might go back in time to change a crucial event.
One common theme is the struggle between good and evil. Hades represents evil, but in fanfiction, there could be a blurring of these lines. For example, he might do good deeds for self - serving reasons that end up having positive impacts. Another theme is family. His relationship with other characters who could be considered family in the Once Upon a Time world, like Zeus or other gods, can be explored. And then there's the theme of fate. Hades is often associated with death and the afterlife, so questions about whether characters can escape their fated deaths through his intervention can be a theme.
One common theme is Morgana's struggle with her powers. In many fanfictions, she's trying to understand and control her magic better. Another theme is her relationship with other characters, like her complex feelings towards Merlin or Arthur.
One common theme could be adventure. Jefferson in fanfiction might embark on exciting quests. Another theme could be self - discovery. He may struggle to find his true place in the world created in the fanfiction. And relationships are also a big theme, like his friendships or romances with other characters.
