The main character is, of course, Shadow the Hedgehog himself. He is the central figure in this dark story. And then there's Dr. Eggman. He often plays a role in Shadow's story, either as an antagonist trying to use Shadow for his evil schemes or as someone who is involved in the events that led to Shadow's creation. There are also other characters like Sonic and his friends who sometimes cross paths with Shadow in this story, and their interactions add more depth to Shadow's dark journey.
Obviously, Shadow the Hedgehog is a main character. He's the one with the vampire - like qualities. Sonic could also be a main character in some fanfictions. He might be in conflict with Shadow because of his new vampire nature or could be trying to help him control it. Amy could be another main character, perhaps she has a special connection to Shadow and tries to understand his transformation.
Sonic is a very popular character to pair with Shadow. Their rivalry and yet potential for teamwork makes for great fanfiction. Tails is also often paired with Shadow. Tails' intelligence can complement Shadow's combat skills. And Knuckles is another one. His strength and connection to the Chaos Emeralds can create interesting storylines when paired with Shadow.
Maybe the main antagonist is a scientist who has been experimenting with vampire-like powers and accidentally creates a powerful vampire - like monster. This monster then starts attacking the world, and Shadow, as a new vampire - hedgehog, has to stop it. The scientist might also be trying to cover up his mistake and will stop at nothing to keep Shadow from interfering.
In the 'Shadow the Hedgehog Pure Dark Story', the main character is Shadow himself. But other characters like Rouge the Bat could also play important roles. Rouge has had a relationship with Shadow in the Sonic universe. She might be torn between helping him out of his dark state or being caught up in the chaos he creates. And then there could be some minor characters who are either victims of Shadow's new - found dark nature or those who try to oppose him in his dark journey.
Shadow might show his love in a very protective way. He'd always be there to keep the reader out of danger, using his speed and strength to shield them from any threats.
Well, the story of 'Shadow the Hedgehog' game is quite engaging. Shadow starts off with a lot of mystery surrounding him. He has super speed and other cool abilities just like Sonic. But his journey is different. He's constantly haunted by his past and questions about his existence. As he progresses through the game, he uncovers more about who he really is. There are levels where he has to fight against enemies that are related to the organization that created him.

One possible Shadow the Hedgehog love story could be that Shadow meets a kind-hearted female hedgehog in the forest. She is always helping other small animals. Shadow, initially cold-hearted, is gradually attracted to her warmth and kindness. As they spend more time together, Shadow starts to open up his heart that was once filled with only vengeance. And they fall in love, sharing adventures and protecting the forest together.
Obviously, Shadow himself would be a main character even in his baby form. Sonic would also be a key character as he is often the hero in these Sonic - related stories. He would likely be involved in trying to figure out how to turn Shadow back. Tails could be another main character as his intelligence would be useful in finding a solution to Shadow's transformation. He might study the cause of it and try to come up with a remedy.
