There might be a wise old grandfather in Sonic's family. He could be the one who knows all the family secrets and ancient techniques. And there could also be some younger siblings, like a little brother or sister who looks up to Sonic and wants to be just like him. They could all have different personalities, for example, the older sister could be really strict but also very protective, while the younger siblings could be full of energy and curiosity.
In this fanfiction, Sonic's family might have some special abilities that they combine with Sonic's speed. For example, his father could have super strength and his mother could have some kind of telepathic power. Together, they could form a super - powerful team to protect their world from the big bads. Also, there could be a lot of family bonding time, like having family dinners and sharing old family stories that Sonic has never heard before.
It depends on the specific fanfiction. In some versions, Sonic might have a brother or sister that the creator has made up for the story. It could be a super - fast sibling like Sonic himself, or one with a different but equally cool power.
It could be a very heart - warming story. Sonic and Amy could be nervous about meeting each other's families. Sonic's friends might also be involved, like Tails could come along to support Sonic. There could be a lot of cultural exchange if their families are from different backgrounds. Maybe there are some family traditions that Sonic and Amy have to participate in, which could lead to some comical or touching moments.
In a Sonic fanfiction where Naruto is abandoned by family, it could be a creative mash - up of two different universes. Maybe the writer wants to explore the idea of Naruto's character in a new and extreme situation. It could be that the 'family' in this context is a fictional or re - imagined version within the Sonic - influenced world.
Obviously, Sonic and Amy are the main ones. Sonic, known for his super speed and heroic deeds. And Amy, who is not only Sonic's admirer but also has her own strong personality. They are at the center of this fanfiction as they are the ones meeting the family.
Sonic, Sonia, and Manic are usually the main focus. They are the core of Sonic Underground and in the reunited fanfiction, their relationships and how they come back together are often explored.
It could be one of Sonic's old enemies who found a way to transform into him. Maybe Dr. Eggman created a sophisticated robot that looks and acts like Sonic.
Amy would also be a likely main character. She's always been very protective of Sonic. So when he has a fever, she'd be right there by his side, doing everything she can to make him comfortable. She could be the one providing emotional support to Sonic during his illness.
There could be new original antagonists created specifically for the fanfiction. These might be dark entities that are related to the source of Dark Sonic's power, trying to either control him or use his power to spread chaos in Sonic's world.
Shadow could be a very challenging opponent. He has similar speed and abilities as Sonic, and in a death battle scenario, his more brooding and sometimes ruthless nature could give him an edge. Plus, if the Sonic watch is involved, Shadow might be more willing to use underhanded tactics to get it for himself or to stop Sonic from using it.
