Stan Lee was an American comic book writer, editor, producer, and publisher. He was the editor-in-chief of Marvel Comics, and later its publisher and chairman, leading its expansion from a small division of a publishing house to a large multimedia corporation. Lee was 95, and his venture into the afterlife was not completely unexpected. The comic book creator lived a long and successful life, and his health has been slowly waning for years. As hard as it is to see him go, his passing is the natural process of everyone that makes it to a ripe old age.
Marvel Studios head Kevin Feige hinted that Lee has a few cameos tucked away. “I’m not going to tell you what specifically,” Feige teased, “but Stan always appreciated a good surprise.”
