Perhaps 'In the World of Markiplier, Reader and Jacksepticeye' would work well. It sets the scene as if there is a whole new world created for these three characters in the fanfiction which can be full of various stories and interactions.
Some popular ones often involve their adventures in fictional game worlds together. For example, there are fanfictions where they team up to fight a powerful villain in a Minecraft - like setting. The characters they play in these stories usually have enhanced abilities and face challenges that test their friendship and skills.
Fanfics of this nature can be a bit controversial as they might cross the boundaries of respect for the content creators. It's better to look for fan - created stories that celebrate their on - screen personas, like their funny moments during gameplay or their interactions with other YouTubers. There are so many positive aspects to focus on rather than seeking inappropriate content.
One characteristic is the emphasis on the male - male dynamic. It may involve creating scenarios where they have deep conversations, share secrets, or have moments of physical closeness. The fanfiction might also play with their individual quirks and personalities, for example, Markiplier's boldness and Jacksepticeye's energetic nature, and how these traits interact in a romantic context. Additionally, the writing might use a lot of descriptive language to convey the emotions between them.
You can find them on fanfiction websites such as Archive of Our Own (AO3). It has a large collection of fan - created works, and you can simply search for 'Markiplier x Jacksepticeye' in the search bar to get a list of relevant fanfictions.
Another option is to check out Tumblr. There are often fanfic writers who post their works there. But again, Tumblr has its own community guidelines. It can be a good source for finding unique and interesting takes on the relationship between Markiplier and Jacksepticeye in a more positive and appropriate way.
One popular Jacksepticeye x Markiplier fanfiction is 'The Adventure Beyond'. It has an interesting plot where they embark on a journey through a magical world together. Another one could be 'The Bond of Brothers' which focuses on their strong friendship in a fictional scenario.
I'm not sure about the most popular ones specifically. However, there are many fanfiction platforms where such works might be found. Keep in mind that yaoi is a form of fan - created content often within the realm of shipping two male characters. But it's important to note that not all fanfiction is of high quality or adheres to the original essence of the characters.
Well, it really depends on one's perspective. Generally speaking, it's not appropriate for a wide general audience. Mpreg is a very specific and often niche genre within fanfiction. It can have elements that are not family - friendly. However, within certain communities of fans who are into this kind of creative and often out - of - the - box storytelling, they might consider it acceptable in their own context. But overall, it's not something that would be considered appropriate for everyone.
Friendship is a very common theme. Since they are both popular YouTubers and often collaborate or are associated with each other, fanfictions like to explore their friendship deeper. Another theme is adventure, as they are known for playing video games which are full of adventures, so it's easy to transfer that into a fanfiction story.
