In a 'dark sonic flash story', Sonic is surely a main character. Given the nature of the story being dark, there could be some new or antagonist characters as well. But Sonic's friends such as Tails, who is his loyal sidekick with his intelligence and mechanical skills, and Knuckles, the strong guardian of the Master Emerald, would probably play important roles too. They would be there to either help Sonic if he's in trouble or try to stop him if he goes too far in his 'dark' state.
Since it's about Sonic, Sonic himself is most likely a main character. There might also be his friends like Tails and Knuckles who would be involved in the story.
The main character is bound to be Sonic in the 'dark sonic flash story'. However, depending on how the story is crafted, other characters could be crucial. Tails, with his ability to build and repair things, would be a great asset in the story. Knuckles, with his strength and connection to the Emeralds, would also be a key figure. And there could be a villain, perhaps an evil wizard or a powerful mechanical being that has the power to corrupt Sonic and set off this 'dark sonic' scenario.
