Without reading the novel, it's impossible to know for sure. But it's likely that the main characters are the nemesis and the protagonist who has a conflict with the nemesis.
Since we don't have much information other than the title, it's difficult to say for certain. However, in a general sense, if it's a 'nemesis novel', it will likely center around a relationship of enmity. And the 'dead at the end' part suggests that this enmity has a deadly resolution. It could be set in a fantasy world where a hero battles their nemesis, a dark wizard perhaps, and in the final encounter, one of them dies. Or it could be a crime - related story where a detective's nemesis, a serial killer, meets their end, along with maybe the detective themselves in a final, fatal confrontation.
I don't know as I haven't read the 'dear nemesis novel'. It could be two rivals from different backgrounds, like a rich and a poor character, or two characters with different beliefs.
There's likely a main character who is facing some sort of nemesis or antagonist. This character probably has some special abilities or qualities that help them in their battles or quests within the graphic novel.
Nemesis is obviously one of the main characters. He is the warlock around which the story revolves.
I don't know for sure. But I'd guess there's probably a hero who is brave and strong, and of course, the nemesis who is the main antagonist.
Captain Picard is one of the main characters. He plays a crucial role in leading the crew against the threats in the story.
In this graphic novel, the Doctor is surely one of the main characters. He is the one who usually opposes the Daleks. The Daleks themselves are central, with their evil intentions and their mechanical forms. There could also be other characters like a local inhabitant of the planet where the story takes place. This character could be someone who helps the Doctor or is in need of the Doctor's help against the Daleks. Maybe there's also a character who has some knowledge about the Daleks' weaknesses and can assist the Doctor in his fight. But overall, the Doctor and the Daleks are the most prominent characters in a story like this.
I'm not sure specifically as I haven't read it, but it could be park workers who are in the thick of the paranormal happenings.
I don't have specific information about the main characters in this visual novel. It could be a group of neighbors living on the dead - end street.
Obviously, Batman is one of the main characters. He is the central figure in any Batman - related story. There may also be some of his well - known villains like the Joker or Bane. They often play crucial roles in putting Batman in difficult situations.
