The main characters are clearly young Joseph and Dio. Joseph is a character with a strong will and unique abilities, especially his Hamon. Dio, on the other hand, is a powerful vampire with his own set of formidable powers.
Perhaps a plot point where the power dynamic between them shifts unexpectedly. Maybe Joseph discovers a weakness of Dio that no one else knew, leading to a very tense and exciting confrontation. In fanfiction, this could be something completely new and creative that the author invents.
The determination of whether the novel 'Dio' is canon can be complex. It might involve factors like consistency with established lore, authorial intent, and the response from the fan community. Without specific details, it's hard to give a definite answer.
I'm not sure exactly who Jonathan Wamback is without watching the story. He could be an ordinary person with an extraordinary story, or someone well - known in a specific community or field.
One common theme is power struggle. Since Dio is a very powerful character in the Jojo universe, when there's a female version or a female related to Dio, she often has to deal with the power dynamics. For example, she might be trying to gain power like Dio or struggling against his overpowering influence.
In my opinion, the Dio manga works quite well. The character development and the way the story progresses are well-executed. Also, the art style adds to the overall appeal.
Mr. Dior's full story did not appear on the Internet in its entirety. It may not be publicly released due to copyright or other factors. However, if you are referring to a particular novel or author's side story, I can do my best to provide you with relevant information.
