Stan Lee (December 28, 1922 – November 12, 2018) was a comic book writer for Marvel Comics who briefly made an appearance in Teen Titans Go! To the Movies. In real life, he was well known for creating some of the most famous superheroes, such as The Fantastic Four, The Hulk, Thor, Spider-Man, and many more.
He was voiced by himself in the feature film.
During the movie, Stan Lee realizes that he's making a cameo in a DC movie, not Marvel. Since that could be copyright infringement or some kind of legal nonsense, he decides to leave. However, he can't help but stay, and later he comes back and randomly shouts "Excelsior!"
- Aside from writing and producing comics, Stan Lee had appeared in numerous superhero movies (almost exclusively Marvel movies). Although he played a big part in their creation, he usually just made a silly cameo.
