The Watchers are a race of fictional extraterrestrials appearing in American comic books published by Marvel Comics. They are commonly depicted as all-powerful beings who watch over the fictional multiverses and the stories that take place in them, and are not allowed to interact with other characters, though they have done so on several occasions, when the situation demanded it. Created by Stan Lee and Jack Kirby, the first Watcher to appear in the comics—named Uatu—debuted in Fantastic Four #13.
