Adolf Hitler was a very bad man who was the leader of Germany during World War II. He did many terrible things, such as starting the war and killing millions of innocent people, especially Jewish people.
Even though he was a bad guy, many people find him interesting and like to talk about or learn more about him. This is called "popular culture." There are many movies, TV shows, books, and video games that have stories about or include Hitler as a character.
Some of these stories are serious and show how bad Hitler was, while others make fun of him or use him as a joke. It's important to remember that even though he is sometimes used in popular culture, Hitler was a real person who did very bad things and should not be glorified or celebrated.
