I'm not sure specifically as there could be many different interpretations of a 'dark sonic flash story'. It might involve a dark or edgy version of Sonic in a fast - paced and perhaps mysterious plot.
Well, it's not straightforward to say. Different comics might portray their speeds differently based on the plot and creative decisions. So, it varies.
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.
Historical fiction is a genre of literature that combines fictional elements with historical events, settings, or characters. For example, a novel might be set during the American Civil War and feature real battles and historical figures, but also include made - up characters and fictional sub - plots.
