I don't know what novel 'great heroes' refer to. This word could have many different meanings and context. If you can provide more information or background, I will try my best to answer your questions.
One common theme is the hero's journey of self - discovery. The hero often starts as an ordinary person and through various challenges, realizes their true potential. Another theme could be good versus evil, where the hero stands up against the forces of darkness. Also, sacrifice is often present, as the hero may have to give up something for the greater good.
There is, of course, the hero themselves. They are often brave and have some kind of special ability or quality. Then there are the sidekicks. These characters support the hero, usually with their own unique skills. And there are villains. They are the ones causing trouble and standing in the hero's way.
Typically, this kind of hero novel often features a protagonist with extraordinary abilities. For example, they might have superhuman strength, intelligence, or unique skills. These heroes usually face great challenges and antagonists, which drive the plot forward. Their moral code is also an important aspect, often being on the side of justice and good.
Well, it could be. Since it's a troubleshooters novel, there might be a lot of problem - solving and exciting scenarios that adventure lovers would find appealing. The hero in the story would probably be involved in some high - stakes situations, which is always exciting for those who like adventure stories.
Maybe it's a novel set in a post-apocalyptic world where the hero was injured in a battle and now relies on crutches to navigate the dangerous terrain and protect others.
A typical one could have the cold hero being a mysterious figure, and the heroine's warmth and determination slowly melt his icy exterior. It might involve a lot of tension and slow-burning romance as they get to know each other.
One challenge could be the acceptance of the relationship by others. People around the hero might not understand this strange union and could be hostile towards it.
