The Doctor is most likely one of the main characters. There could also be his companions, though without more specific knowledge about this short story, it's hard to say exactly who else.
The story might be about the Doctor facing some kind of threat related to a 'ghost in the machine'. It could involve a computer or technological system that has an unexpected and perhaps malevolent presence within it, like a digital entity that is causing trouble or mystery.

I'm afraid I can't tell you who the author of 'the great core's paradox novel' is. There are so many novels in the world, and this one might be from a niche genre or a self - published work. Maybe you could try looking it up in specialized book databases or asking in literary forums to find out more about the author.
The main characters include The Flash, who sets off the events of the story through his time - traveling actions. Batman, who has his own unique story arc within this altered universe. And Aquaman, whose actions and decisions contribute to the overall chaos and conflict in the 'flashpoint paradox graphic novel'. There are also other characters like Wonder Woman, who are involved in the complex web of events and relationships in the story.
I'm not sure specifically as I haven't read it. But it could be the time - traveler who is at the center of the grandfather paradox situation, and perhaps their grandfather if he is a part of the past that is being interacted with.
