A common theme is power - up. Naruto, already powerful in his own universe, often gains new abilities or levels up in the SAO world in these fictions.
The theme of adaptation is also prevalent. Naruto has to adapt to the virtual reality environment of SAO, which is very different from the Hidden Leaf Village. He has to learn about the game mechanics, like how to use swords effectively (since he is mainly a ninjutsu user in his own world), and this journey of adaptation makes for an interesting read.
One common theme is adventure. Writers often put them on exciting quests within the Sword Art Online world. Another theme is friendship evolving into something more. As they go through various challenges together, their relationship deepens.
Overcoming challenges is another theme. Since Sword Art Online is a game full of dangerous monsters and difficult quests, the OCs have to face numerous challenges. These can range from fighting powerful bosses to dealing with glitches in the game system. How they overcome these challenges and grow as a result is a key part of many fanfictions.
One common theme is character development. Since it's reaction - based, it often shows how characters grow and change in response to different events. For example, Kirito might react to a new threat in the game, and through that, we see his character evolve.
One common theme is the power of love in a virtual and dangerous world. The love between characters often gives them the strength to overcome challenges in the game.
In Sword Art Online fanfiction, power - up and character development are frequently seen themes. Writers may focus on how the characters gain new skills or abilities and how these changes affect their personalities and relationships. Additionally, the theme of survival against the odds is also common, given the life - or - death nature of the game in the original series.
One common theme is the crossover of power systems. In these fanfictions, you often see the characters from Sword Art Online with their unique skills in the RWBY world, and vice versa. For instance, Kirito's swordsmanship in the RWBY universe where Dust and semblances exist.
One common theme is the power - up of the original character (OC). In many of these fanfictions, the OC starts off as an average player in Sword Art Online but then gains unique abilities or skills that help them stand out. This often attracts the attention of other characters, leading to the formation of the harem.
One common theme is the exploration of the NPCs' sentience. Many fanfictions wonder if the NPCs in Sword Art Online could truly have feelings or self - awareness. Another theme is the idea of NPCs breaking free from their pre - determined programming. For example, in some fanfictions, they start to act independently of the game's original design.
One common theme is her growth as a character. In many fanfictions, Sinon starts as a somewhat reserved or fearful character in ALO and gradually becomes more confident and powerful. Another theme is her relationships, such as her friendship with other players or her mentorship of newbies in the game.
One common theme is the struggle for power. Male OCs often strive to become stronger in the game world, whether it's to protect themselves or others. For example, they might be seeking rare items or leveling up their skills at a rapid pace.
