One popular trope is the 'enemies to lovers' trope. Hook starts off as a bit of an anti - hero, so it's common to see stories where he and another character, often Emma, start off on the wrong foot but then gradually fall in love. Another is the 'time - travel' trope. Given the magical nature of the 'Once Upon a Time' universe, it's not unusual for fanfictions to involve characters traveling through time, which can create really interesting plotlines.
The 'alternate universe' trope is widely used. Writers create different versions of the 'Once Upon a Time' world, for example, a modern - day setting where the characters are regular people but still have some of their magical traits. In these AUs, Hook might be a pirate in a more contemporary sense, like a smuggler on the high seas. These different settings allow for new and creative interpretations of the characters' relationships and story arcs.
The 'hurt/comfort' trope is quite prevalent too. For example, when Hook gets injured and Emma takes care of him, or vice versa. It shows their deepening connection. Also, the 'time - travel' trope can be found, where they might go back in time and experience events that change their relationship in the present. This adds an interesting layer of complexity to their story.
The 'soulmate' trope is also quite prevalent. In these stories, Hook and Emma are often portrayed as being fated to be together, with some magical or supernatural force binding them. And of course, the 'hurt/comfort' trope, where one of them gets hurt and the other is there to comfort and heal them. This trope can add a lot of emotional depth to the stories.
