A prevalent theme is the exploration of Holmes' character through the eyes of the reader. This could involve delving into his brilliant mind, his eccentricities, and his complex personality. Also, the setting of Victorian London is often a key theme, with detailed descriptions of the fog - filled streets, the hansom cabs, and the gas - lit alleys. And of course, there are often themes of redemption and self - discovery for both the reader and Holmes within the stories.
Another theme is the mystery - solving aspect. Fanfictions usually have them working together to crack cases, with Holmes' brilliant mind and Watson's practical knowledge. In 'The Mystery of the Missing Heirloom' fanfiction, they use their combined skills to find the heirloom. Watson provides medical insights that help Holmes piece together the clues.
The theme of power dynamics is often explored. Sherlock is a very intelligent and dominant character, and the OC may either challenge that or submit to it. This creates tension and interesting plotlines. For example, an OC who is just as intelligent as Sherlock may constantly compete with him, leading to a battle of wits that is exciting to read.
A common theme is family. Since they are siblings, fanfictions often explore their family bond, whether it's a strained relationship at first that gradually improves, or a strong bond from the start that they rely on during cases. For example, in some stories, Sherlock initially underestimates Enola but then realizes her value as a family member and detective.
One common theme is the deepening of their friendship. Many fanfictions explore how they become closer and more reliant on each other over time. Another theme is mystery - solving together. They are often depicted as an unbeatable team in solving complex cases. And of course, there's the theme of loyalty. Their loyalty to each other is a central aspect in a lot of these fanfictions.
A prevalent theme is the exploration of intelligence. Holmes' deductive reasoning is pitted against the ninja's instincts and knowledge. Also, friendship can be a common theme. Just as Naruto values his friends, Holmes might form new relationships in the Naruto universe. And there's often the theme of adaptation, as Holmes has to adapt to a world full of chakra and jutsus instead of the streets of London.
The theme of adaptation is quite common too. Sherlock Holmes has to adapt to the strange new world of Naruto, with its different rules, powers, and social structures. At the same time, Naruto characters might have to adapt to Sherlock's rather un - ninja - like ways of doing things. And there's also the theme of uncovering secrets. Sherlock's nature of uncovering hidden truths fits well with the Naruto world which is full of secrets, be it about the origin of certain jutsus or the true motives of some characters.
The theme of justice is also very common. Both Sherlock Holmes and Batman are dedicated to bringing criminals to justice. In fanfiction, they often team up or compete in the pursuit of this goal. They might have different ideas about what justice means exactly, but they both strive to make their respective worlds a better place by stopping the bad guys.
Another theme is the power of intellect. Both Harry Potter (even in the fem version) and Sherlock Holmes are highly intelligent in their own ways. Fanfictions usually play on how their combined intelligence can solve complex problems that neither could solve alone. For example, in many stories, they might be trying to solve a mystery that involves both magic and non - magic elements. The female Harry Potter can use her knowledge of magic and Holmes his deductive skills to get to the bottom of things.
One common theme is the unspoken attraction. In these fanfictions, there's often a lot of tension between Holmes and Watson because they can't immediately act on their feelings. Another theme is loyalty, which is a big part of their relationship in the original stories and is intensified in the yaoi versions.
There are those where the reader is a witness to a crime that Holmes is investigating. In this fanfiction, the reader has some special knowledge or ability that helps Holmes piece together the puzzle. It often has a lot of back - and - forth dialogue as Holmes tries to extract the relevant information from the reader while also protecting them from the criminals.
