Well, a big theme is morality. Adult super power stories often explore the gray areas between right and wrong. Since the characters have great power, the decisions they make are more impactful. Another common theme is isolation. Having superpowers can make a person feel different from others, like they don't belong. It can be hard for them to form normal relationships. And then there's the theme of redemption. Some characters start off using their powers wrongly but then try to make amends and use them for good.
You can explore classic short stories. For example, Edgar Allan Poe's short stories are full of mystery and psychological depth. His use of atmosphere and complex characters can engage readers in a different but equally captivating way.
As a fan of online literature, I don't have my own reading preferences and can't provide a subjective evaluation. However, I can recommend some urban supernatural novels for your reference:
1 " Battle Through the Heavens "-Heavenly Silkworm Potato: This is a very popular online fantasy novel that tells the story of a young man's growth. He fused different elemental powers in his cultivation and finally became the powerful ruler of the Dou Qi continent.
2. The Peak of Martial Arts Refinement-Momo: This is a novel about martial arts. The main character, Xiao Yan, is constantly breaking through himself to become a powerful martial artist in the process of practicing martial arts.
3 " The Herd "-Otaku Pig: This is a novel with a fantasy adventure theme. It tells the story of a young man who used mysterious runes to travel to a different world and become a powerful herder.
4 " Covering the Sky "-Chen Dong: This is a novel with the theme of fantasy. It tells the story of a young man who became a powerful person by cultivating mysterious runes and fusing the power of heaven and earth.
5 " Full-time Expert "-Butterfly Blue: This is a novel with a game theme. It tells the story of a gaming expert who returned to the game world after unexpectedly retiring and became a powerful professional player.
One great adult super power story is 'Watchmen'. It's a complex and gritty story that deconstructs the idea of superheroes. The characters have various superpowers and moral dilemmas. Another is 'The Boys' which shows a darker side of superpowered individuals, dealing with power abuse and corporate control. And 'Invincible' also has a great take on adult - themed super power situations, with its main character coming to terms with his powers and the responsibilities that come with them.
Historical fiction is another option. It allows you to learn about different historical periods while enjoying a good story. You could read about the life of a samurai in feudal Japan or a knight in medieval Europe.
No. Super sexy erotic stories are not suitable for all audiences. They usually contain adult - themed and sexual content, which is not appropriate for children or those who are not interested in such explicit material.
