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.
The main characters are, of course, Dark Sonic and Shadow. Dark Sonic is a more menacing and chaotic version of Sonic. He has a darker personality and often acts on more primal instincts. Shadow, on the other hand, is a complex character with a tragic past. He is a powerful hedgehog created by humans. In the fanfiction, they are the central focus, with their interactions driving the story forward.
Dr. Eggman might also be a part of the story. He's the main antagonist in the Sonic series. His evil plans could be the catalyst for Sonic and Shadow's encounter. Whether it's stealing chaos emeralds or creating some new doomsday device, Eggman's actions could force Sonic and Shadow to interact and either fight against or alongside each other.
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.
Sonic would probably be very shocked at first. He trusts Amy, so her betrayal would be unexpected. He might initially try to talk to her to understand why she did it.
Tails would probably be very curious and eager to figure out how to change Sonic back. He might study Sonic's new form scientifically. Knuckles, on the other hand, would be a bit more confused but still stand by Sonic's side. Amy might be initially jealous because she's used to being the main female around Sonic, but then she could become a great friend and help Sonic adjust. Dr. Eggman would likely see this as an opportunity to take advantage of Sonic's confusion in her new form.
Yes, there are quite a few out there. Some can be found on popular fanfiction websites. You might need to search through the Sonic the Hedgehog fanfiction section specifically. However, the quality can vary greatly.
One great aspect of Sonic Shadow and Silver fanfiction is the exploration of different character dynamics. Writers often create unique relationships between these characters that we might not see in the official games. For example, they could show Shadow and Silver teaming up in a new adventure, facing challenges that test their skills and friendship. Fanfiction also allows for the expansion of their backstories. Maybe Silver's time - traveling abilities are explored in more depth, or Shadow's past traumas are delved into in a way that gives a new perspective on his character.
In the world of 'Shadow and Sonic Fanfiction', 'The Lost Memories' is a must - read. It's about Sonic losing his memories and Shadow having to help him. The story does an amazing job of exploring their relationship in this difficult situation. 'Sonic's Darkest Hour' is another one where Shadow comes to Sonic's rescue in a really unexpected way. Also, 'Shadow and Sonic: The Race for Power' is engaging as it pits them against each other in a new kind of power struggle.
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.
