The 'soulmate' trope also shows up a lot. In these fanfictions, the idea is that the reader and Tom Felton are somehow meant to be together. It could be a magical bond or just a feeling they both can't ignore. This trope often leads to very romantic and sometimes even a bit fantastical stories as the two characters are drawn to each other against all odds.
One great 'Tom Felton x Reader Fanfiction' is 'A Magical Encounter'. It beautifully weaves a story where the reader character meets Tom Felton in a magical setting, perhaps at a wizarding event. The story is full of sweet moments and interesting dialogues that make it a joy to read.
One common trope is the 'stranger in Middle - earth' where the reader is from our world and somehow ends up in Middle - earth and meets Bilbo. Another is the 'unlikely pair' trope as Bilbo is a hobbit and the reader is usually a human or some other being, so their relationship is seen as an unlikely but interesting one.
The 'Forbidden Love' trope is quite popular. Maybe Robin is from a different group or has a secret that makes the relationship with the reader seem impossible at first. It adds a lot of drama.
The 'hurt/comfort' trope is very common. It often involves the reader character going through some sort of emotional or physical pain, and Patton being there to comfort them. For example, the reader might be feeling lonely or sad, and Patton's warm presence makes them feel better.
Another popular trope is the 'Underdog Romance'. Robbie is often seen as an underdog in the iCarly universe. Fanfics use this to create a story where the reader sees the good in Robbie that others might overlook and falls in love with him because of his unique qualities, like his creativity and loyalty.
One popular trope is the 'genius and the normal'. Since Spencer Reid is a brilliant genius, it's common to see stories where the reader is an 'ordinary' person who is drawn to his intelligence. Another is the 'hurt/comfort' trope. Reid has been through a lot in the show, so fanfictions often have the reader comforting him. For example, after a tough case.
In Pokemon X Male Reader fanfiction, the 'Lost in a New World' trope is often seen. The male reader is somehow transported to the Pokemon world and has to adapt.

Another trope is 'Redemption Arc', where a previously antagonist character or Pokemon is redeemed through the male reader's influence.
Well, a common trope is the 'roommate' situation. In reader x reader fanfiction, it can lead to a lot of fun and sometimes awkward moments as the two readers live together. There's also the 'fake relationship' trope. They might pretend to be in a relationship for some external reason, like to make someone else jealous or to get into an exclusive event. And the 'reunited after years' trope is also seen often, where the two readers meet again after a long time apart and old feelings resurface.
One popular trope is the 'Forced Proximity'. For example, Masky and the reader might be trapped in a small space together, which forces them to interact and get to know each other on a deeper level. Another is the 'Mysterious Protector' trope, where Masky secretly looks out for the reader, and the reader gradually discovers this. It adds an element of mystery and intrigue to the story.
The 'redemption' trope can also be found in vanitas x reader fanfiction. The idea that the reader might be the one to bring out the better side of Vanitas.
