Overseas manga
Manga is enjoyed not only in Japan but also overseas. For example, remember Marvel Comics. All the famous characters that come to mind when you hear their names, such as Spider-Man, Superman, and Batman, are characters from Marvel Comics.
Marvel and movies
The characters in Marvel Comics are often made into movies. Thanks to that, the name recognition in Japan is also quite high. It would be an interesting phenomenon that characters other than justice heroes are gaining popularity both overseas and in Japan. Batman’s Joker, Spider-Man’s Venom, and the dark hero Deadpool. Is empathy for the negative side of human beings creating the popularity of these characters?
