One possible theme could be their friendship. Vivi was an important part of the Straw Hat crew's journey in the Alabasta arc. Fanfictions could focus on how they became friends, like how Luffy's simple - minded but kind nature won Vivi over, and how they supported each other during battles and difficult situations.
One possible theme could be mentorship. Kushina could be portrayed as a mentor to Sakura, guiding her in areas like dealing with strong - willed men, given Kushina's relationship with Minato. Another theme might be friendship. They could bond over their shared experiences of being in a world full of powerful shinobi.
One possible theme could be their deep friendship. They could be shown supporting each other through tough times, like when facing a powerful enemy. Another theme might be their growth as ninjas. For example, they could train together and learn new techniques from each other.
Another plotline could revolve around them working together to save a comrade. They have to combine their skills, with Ichigo's brute strength and Unohona's healing abilities. Along the way, they start to understand each other's values better. Unohona might see Ichigo's unwavering determination in a new light, and Ichigo could respect Unohona's calm and collected nature even more. It's a story of friendship and cooperation.
Maybe they team up to train new superheroes. They could share their knowledge and skills, like Spiderman teaching about using the environment to your advantage and Supergirl showing how to control super - strength. This would create a story of mentorship and cooperation between two very different heroes.
One possible plotline could be a female Goku going on a special training journey. She might discover new powers or techniques and form new friendships along the way. For example, she could meet a character from another part of the Dragon Ball universe and they could team up to face a common threat.
Another plot could be that the OC has a special power or ability that Darkiplier needs to achieve a certain goal. So, they form an alliance. Along the way, they develop a deep bond, like a brother - sister type of relationship. They share their backstories and support each other through difficult times, all while on this quest related to Darkiplier's goal.
The theme of family could be prominent. Since they have known each other since childhood, they are like family in a way. Fanfictions might show how they deal with the concept of family, whether it's creating a new family unit of their own or how their relationship is different from a typical family relationship but still holds that sense of closeness.
Yes, there might be such fanfictions out there. The world of fanfiction is vast, and with the popularity of the 'One Piece' characters Luffy and Vivi, it's possible that some fans have created stories around this concept. However, the quality and nature of these fanfictions can vary greatly. Some might focus on the relationship development that could lead to such a situation, while others might take more creative and unexpected turns.
I'm sorry, but 'lemon' in fanfiction often implies inappropriate or adult - themed content. However, there are many great non - 'lemon' fanfictions about Luffy and Vivi. You can check out platforms like FanFiction.net or Archive of Our Own to find some family - friendly stories about their adventures and relationship.
Luffy would be the central figure. His relationship with Vivi is one of friendship and mutual respect. In the context of a harem, Luffy might not fully understand the concept at first. Vivi, on the other hand, could act as a mediator or an equal partner among the female characters in the harem. The harem members could all be united by their admiration for Luffy and his noble goals.
