One popular theme is the main character using their gaming knowledge to quickly gain power in the new world. For example, they might know strategies for combat or leveling up from the games they played in their previous life. Another theme is the discovery of unique game-like systems in the new world that only the reincarnated character can fully understand or manipulate. Also, there is often the theme of the character forming a harem or a group of loyal followers due to their op (overpowered) abilities.
Social interactions would be very different. Dragons are often seen as solitary or living in small groups. Other creatures might fear the dragon, so it would have to be careful not to intimidate them too much if it wants to have any sort of positive interaction. It could also use its power to protect weaker creatures, which might earn it respect and some form of friendship.
One could expect powers like super strength, flight, and the ability to breathe fire or other elements. Dragons are often depicted as very powerful in fiction, so being reincarnated as one might come with enhanced physical abilities, such as being able to carry heavy loads or move at great speeds. Their flight would give them an advantage in both battle and exploration. And the ability to breathe fire or other elements could be used for offense or defense.
I think being reincarnated as Loki would be super interesting. He's such a complex character with his own motives and schemes. You could take over Loki's life at a certain point and use your modern - day knowledge to either further his plans in a different way or completely change his path. Maybe you could prevent him from getting into so much trouble with Thor and the Avengers, or use his shapeshifting abilities in ways that no one in the Marvel universe has ever seen before.
Tony Stark is also often reincarnated. It gives the opportunity to change the course of his life. For example, the reincarnated Tony could prevent some of the mistakes he made in the original story, like creating Ultron, or he could be given a different set of skills or knowledge at the start of his journey as Iron Man.
It would be an exciting adventure. You could potentially meet your favorite Marvel characters, like Iron Man or Captain America. Maybe you'd get superpowers and join the Avengers in their battles against evil. It's a chance to be part of the amazing Marvel universe in a unique way.
Well, one possibility is that the OP OC could quickly rise to power within the game world of Log Horizon. They might use their overpowered abilities to solve problems that the original characters struggle with, like dealing with the political unrest in the city - states. Maybe they could also introduce new combat techniques or magic spells that change the way battles are fought in the fanfiction.
I'm not sure of all the well - known authors specifically in this genre, but there are some who have a following. Some authors might be relatively unknown but have a very dedicated readership within the fanfiction community. There could be some who started writing these stories on platforms like Wattpad or Fanfiction.net and gained popularity over time.
One interesting concept could be the idea of having knowledge from our world and using it in the Marvel universe. For example, knowing the future events of certain storylines and trying to change or manipulate them for the better. Another concept might be the unique powers the reincarnated character could gain, like a combination of powers that don't exist in the original Marvel canon.
Well, a cool plot could be reincarnating into the body of a Stark Industries employee. You then use your knowledge of future tech from your past life to revolutionize Stark's inventions even further. This could lead to new and improved Iron Man suits way before they were originally created in the Marvel timeline. Or, you could be reincarnated as an Asgardian commoner but with a deep knowledge of Earth's cultures. You could introduce things like rock music to Asgard, creating a whole new cultural exchange between the two realms.
