Who are some popular characters that could be used in 'unexpected love fanfiction'?

Darth Vader from the Star Wars Galactic Empire could be a great character in an empire crossover. His dark and powerful presence would add a lot of drama. Also, Emperor Palpatine. In a crossover with another empire, they could be the antagonists trying to take over the new empire. Another character could be Captain America from the Marvel universe. If you consider the United States in the Marvel world as an 'empire' of sorts in terms of power and influence, his sense of justice and leadership could be interesting when put against the values of another empire.

Hermione Granger from the Harry Potter series could be an interesting character. Imagine if she was hypnotized to forget all her magical knowledge. Another could be Katniss Everdeen from The Hunger Games. Hypnotizing her to not be able to use her archery skills would create a whole new set of challenges for her.

Sherlock Holmes could be an unexpected character in Pinocchio crossover fanfiction. Holmes could use his deductive skills to figure out why Pinocchio's nose grows when he lies and might even try to find a way to control it. Another one could be Alice from Wonderland. Her strange adventures in Wonderland and Pinocchio's own adventures could combine in interesting ways, like exploring a new and magical land together.

Captain America could be a great character to use. He was a WW2 soldier himself, so it would be easy to create a crossover where he meets other soldiers from different parts of the war or different universes. Another one could be Indiana Jones. His adventurous spirit combined with the skills of a WW2 soldier could make for an exciting crossover. Also, Sherlock Holmes could be used. The WW2 soldier's practical knowledge and Holmes' deductive reasoning could lead to some interesting storylines.

Peter Parker from Spider - Man could be an interesting choice. Imagine if Peter was turned into a girl. He would still have his spider - powers, but would have to deal with the added complications of being a female superhero in a male - dominated world.

Filch could be an unexpected character. He might enter the tournament in a comical way, like he accidentally stumbles into the selection process and ends up being a participant. Another could be Peeves. He could disrupt the tournament in his usual mischievous way, or perhaps he is made a part of a task where the competitors have to outwit him.

How about including characters from Sailor Moon? It would be really interesting to see the Gokaigers interact with the Sailor Scouts. Maybe they could learn some new strategies from the Scouts' magic-based attacks.

Well, characters from Studio Ghibli movies could be really interesting. For instance, Totoro could be a strange and powerful ally in the Persona 3 world. His large size and gentle nature could be a contrast to the often - dark and brooding Persona 3 characters. He could use his magic to help them in battles against Shadows in unexpected ways, like creating huge gusts of wind to blow the Shadows away.

The Doctor from SCP Foundation. It would be really interesting to see how the chaotic and often dangerous world of SCP would interact with the universe of Honkai Impact 3. The Doctor's knowledge and often unethical experiments could bring a whole new level of conflict and mystery to the crossover.

How about characters from a detective anime like Detective Conan? Conan's sharp mind and deductive skills could be really useful in the world of Fushigi Yuugi. He could help solve some of the mysteries that the characters encounter, especially those related to the political intrigue in the different kingdoms. His presence would also add an element of modern - day thinking to the more traditional fantasy setting of Fushigi Yuugi.
