Another great one is 'Watchmen' by Alan Moore. It's not just a superhero story but a deconstruction of the genre. The characters are morally ambiguous, and the complex narrative and detailed art make it a must - read. It also has a lot of political and social commentary.
I think Spider - Man from Marvel has an amazing story. Peter Parker is just an ordinary kid who gets superpowers by accident. He has to juggle his normal life, including school and relationships, with his new responsibilities as a superhero. His struggles are very relatable. He faces financial problems, has to keep his identity a secret, and still tries to do the right thing. It's a story that shows that with great power comes great responsibility.
First, think about what makes your superhero stand out. Maybe it's a never-before-seen power or a really compelling origin story. Also, consider their moral code and how they'll interact with the world. It's all about creating a character that people will root for.
DC Comics' inaugural superhero was Superman. His appearance marked a significant milestone, shaping the direction of superhero comics. Superman's strength, moral code, and popularity have endured over the years.
