One often - seen trope is the 'oc with a special power'. This power can either be a threat or an asset to the Akatsuki. It creates interesting dynamics as the Akatsuki members might want to use the oc for their power or protect them from others who would. Also, there's the 'redemption arc' trope for the Akatsuki through the oc's influence. The oc might make one or more of the members question their actions and seek a different path.
One common trope is the 'fish out of water' situation. For example, if the OC is from a different time or place than the canon world, like an OC from modern times ending up in Middle - earth in a Lord of the Rings 'oc x cannon fanfiction'. Another is the 'love at first sight' trope, where the OC and the canon character fall for each other immediately. It's often used to quickly establish a relationship in the story.
A common theme is loyalty. The Akatsuki members are often portrayed as being loyal to protecting the OC, even if it goes against their usual motives. Another theme is the power dynamic. Since the Akatsuki are generally powerful, the relationship between their strength and the vulnerability of the OC can create interesting stories.
One common theme is the power dynamic. Akatsuki Kain often has certain powers or abilities, and exploring how the OC interacts with that, whether in fear, admiration, or trying to equalize it, is popular. Another theme is the discovery of self. The OC might find new aspects of themselves through their relationship with Kain.
One popular trope is the redeemed Akatsuki OC. This is where the character starts off as a typical Akatsuki member, but through interactions with the main Naruto characters, they see a different way and change their ways. Another trope is the hidden - identity OC. They pretend to be one thing within the Akatsuki, but in reality, they are working against the group for a greater good. The love - interest trope is also common, where the OC has a romantic relationship with one of the Naruto characters, like Sasuke or Naruto, while being part of the Akatsuki.
One common trope is the over - protective yandere. The yandere character in these fanfics often goes to extreme lengths to protect the Marvel OC, even if it means going against other characters or the law. For example, they might fight off villains in a very brutal way just to keep the OC safe.
A common trope is the 'forbidden love' trope. Since Sebastian has his own duties and often a dark nature in many interpretations, a relationship with a female oc can be seen as something that goes against the norm or is dangerous. Another is the 'damsel in distress' trope where the female oc gets into trouble and Sebastian has to save her.
One common trope is the 'opposites attract' scenario. The grand highblood's often menacing or complex nature is contrasted with the oc's more innocent or different qualities. This creates a dynamic relationship.
Well, one common trope might be the 'damsel in distress' where the abused oc is constantly in need of rescue. Another could be the alpha's over - the - top possessiveness being seen as a form of 'love' even though it's not healthy. But again, this is a rather dark and not - so - positive set of tropes.
One common trope is the 'forbidden love' between the OC and Dracula. The OC, whether human or vampire, finds themselves drawn to Dracula's dark allure despite the danger. Another is the 'newbie in the vampire world' trope, where the OC is a newly turned vampire trying to navigate the rules and power dynamics in Dracula's domain.
A popular trope is the 'power couple' idea. In the DC universe, Talia al Ghul has a certain amount of power and influence. When paired with a male oc, they can become a force to be reckoned with. The male oc might bring in new skills or knowledge, like advanced technology or magic, that complements Talia's own skills. Also, the 'redemption arc' trope can be seen, where the male oc helps Talia move away from her more villainous tendencies.
