A sense of isolation can be a theme too. Even though they might be surrounded by people in the new world, the resummoned hero may feel alone because they are different. Their knowledge from their previous world may not be fully understood by the natives of the new world. They often have to find their place in this new society while still holding onto a part of who they were in their original world.
Sure. 'The Rising of the Shield Hero' is a popular one. In this novel, the hero is summoned in a rather unexpected way and has to face many challenges in a new world.
The theme of legacy also exists. The retired hero wants to leave a positive mark on the world. He might train a new generation of heroes or complete a final mission that will be remembered. For instance, an old superhero might pass on his powers or knowledge to a young protégé, ensuring that his heroic values are carried on.
Love is a common theme. For example, in 'Twilight', the love between Edward and Bella is a central part of the story. Another theme is the struggle between good and evil, like in 'The Mortal Instruments' where the heroes fight against the forces of darkness. Also, self - discovery is often there as the heroes usually learn more about their own powers and identities in the paranormal world.
One common theme is the power struggle. The hero usually starts with less power compared to the boss, but through a series of challenges, they grow in strength. For example, in 'The Matrix', Neo is the hero and the machines are the bosses. Neo has to overcome the powerful control of the machines.
Often, self - discovery is a theme. In 'The Adventures of Huckleberry Finn', Huck goes on a journey that helps him discover who he really is. Individualism is another common theme. American heroes in novels tend to be individuals who go against the norm or fight for their own beliefs. And of course, there's the theme of survival, like in 'The Call of the Wild' where Buck has to survive in the wild.
A common theme is heroism. The Spear Hero is usually on a journey to prove himself and save the day. Another theme is often the power of the spear as a weapon, and how it can be used for good or evil depending on the wielder.
One common theme is heroism itself. The heroes in these novels often display courage, like in 'The Lord of the Rings' where Aragorn shows great courage in battle. Another theme is the journey or quest. For example, in 'The Odyssey', Odysseus' journey home is full of trials.
Empowerment is a common theme. Girls in these novels often start in a position of relative weakness or being underestimated but then rise to power. For example, in 'Matilda', Matilda is a little girl in a world that doesn't understand her intelligence at first. But she uses her powers (both mental and new - found confidence) to overcome obstacles like her mean parents and the cruel headmistress.
One common theme is the conflict between duty and love. The hero is usually on an important undercover mission, and falling in love can put that mission at risk. Another theme is secrecy. The hero often has to keep his true identity a secret from the heroine, which adds a lot of tension to the relationship.
The theme of redemption can also be common. Maybe the blind hero has had a difficult past or has made mistakes. Through the love of the heroine, he finds a way to redeem himself. This can involve him becoming a better person, learning to forgive himself, and finding a new purpose in life. It makes the story not just about love but also about personal growth and transformation.
