These fanfictions usually play with the personalities of Sonic and Shadow. For example, Sonic might be shown as more vulnerable or Shadow as more affectionate than in the official stories. They also tend to have a lot of detailed descriptions of their interactions, both physical and emotional. This can include things like longing looks, secret meetings, and passionate embraces. Since they are lemon fanfictions, there can be sexual undertones, but good ones also have a proper story arc and character growth. They may also explore themes like forbidden love or the struggle to come to terms with new - found feelings.
One popular sonic and shadow lemon fanfiction is 'Sonic's Hidden Desires'. It delves into a rather complex relationship between Sonic and Shadow with some intense emotional and romantic elements. However, it's important to note that such fanfictions might not be in line with the official canon of the Sonic series.
I'm sorry, but 'lemon' in fanfiction often implies adult and inappropriate content, so I can't recommend such works. However, you can look for regular Sonic and Shadow fanfiction that focuses on their friendship, adventures or other positive themes on fanfiction websites like Archive of Our Own.
Another aspect could be the development of their individual personalities within the fanfiction. Female Sonic might have different traits from the male Sonic, and the same goes for Shadow. The fanfiction could focus on how these differences play out when they are together. For example, if female Sonic is more empathetic, she might be able to reach Shadow on an emotional level that the male Sonic couldn't. This can create interesting storylines that are not at all related to adult content.
Another reason is the creativity of the plots. Since it's fan - made, there are no real boundaries. A story could combine elements from different Sonic games or even introduce entirely new concepts. For example, a fanfic could have Shadow and Silver discover a new form of Chaos energy that changes the power balance in their world.
I'm not sure specifically about 'lemon' fanfictions as they often involve inappropriate content. However, there are many great Sonic x Shadow fanfictions that focus on their relationship in a more positive and clean way. You can try looking on fanfiction websites like Archive of Our Own or FanFiction.net and search for Sonic x Shadow fics, then filter through to find ones that suit your taste.
The lemon aspect, of course. This usually involves some form of romantic or sexual tension between the two characters. It can range from subtle glances and unspoken feelings to more explicit scenes, depending on the writer's style and the rating of the fanfic. But it's what gives the 'lemon' part of the genre its name. Also, the setting often plays a role. It could be set in the familiar Sonic universe, or sometimes in an alternate dimension created by the author to explore their relationship without the constraints of the main storyline.
Tails is a very popular character to include. He is Sonic's best friend and his technical skills can add a lot to the story. For example, he could help Sonic and Shadow figure out some complex machinery or technology that is part of the plot.
In Sonic x Shadow Yaoi Lemon Fanfiction, the theme of self - discovery is often present. Both Sonic and Shadow are well - known characters with their own identities.

And Shadow, who is often solitary, could learn about the joys of companionship. This kind of exploration of character growth within the relationship is a popular theme.
