Typically, the vampire Sonic and the werehog are the central figures. But sometimes, there are side characters like Tails or Knuckles who might be involved in the story too. For example, Tails could be helping Sonic deal with his vampiric powers while Knuckles might be in charge of the security at the werehog camp. So, it really depends on the specific fanfiction, but Sonic and the werehog are almost always the main focus.
Sonic, of course, is often one of the main characters, either as the vampire or having some sort of encounter with the vampire. And the werehog is also a main character. There could also be other characters from the Sonic universe who are part of the werehog camp.
Main characters usually include Sonic in his vampire or normal form, the werehog which could be an original character or an existing Sonic character transformed. Then, there are often characters like Amy who might be at the werehog camp and play a role in either befriending or being suspicious of Sonic. There could also be some elder werehogs in the camp who act as mentors or authority figures and have a say in how the werehog community interacts with Sonic the vampire.
One interesting plot could be a vampire Sonic having to team up with a werehog to protect their camp from an outside threat, like a powerful dark force. They have to overcome their natural differences and learn to work together.
One common theme is the struggle between good and evil. The werehog, often representing the more wild and instinctual side of Sonic, and the vampire, usually a symbol of the dark and mysterious, are pitted against each other. Another theme is identity. Sonic has to deal with his dual nature as a werehog while facing the vampire threat.
A common theme is the battle between good and evil. Sonic, as the hero, usually has to fight against the vampire demons which represent the evil side. Another theme is the struggle with one's inner self, especially for the werehog character who has to deal with his dual nature.
I think Knuckles would be a great addition. He could provide some interesting dynamics with Sonic the Werehog. Since Knuckles is strong and has his own set of abilities, he could either be a helpful ally or, in some cases, a bit of a rival in the crossover world. For example, if they were in a world where there was a limited amount of power - like special gems that both of their powers rely on - there could be some tension between them as they try to figure out how to share or compete for those resources.
