The Watcher is many times the superior of any mere man. All he does is travel his lonely route, stopping from time to time to look around as history unfolds. It is as if his only mission is to watch. His home planet is at the furthest end of the known universe, a planet containing the greatest scientific wonders of all time. If one was to seize some of these scientific treasures, he would have such power as no human has ever dreamed of possessing.
One of the first races in the universe, The Watchers developed technology and evolved billions of years before nearly all species. With the best of intentions the Watchers used this knowledge to interfere with the evolutionary and technological advancements of a primitive species. The residents of Prosilicus, not ready for these advancements annihilated one another with this new technology.
The Watchers horrified by these actions, swore to only observe and never to interfere with the happenings of the universes
Later, A Watcher observed a not yet formed Galactus in a cocoon. Honoring their oath of non-interference the Watcher watched as Galactus came to be the Devourer of Worlds.
The Watcher assigned to observe Earth and its solar system is named Uatu. Uatu has broken his oath on numerous occasions.
The first time that the watcher came to Earth was when a future Captain America was sent back in time to 1602 A.D., he then got help from a Elizabethan-era version of Doctor Strange who helped create a time portal fixing the reality of Earth.
In a more modern time Uatu was first seen by the Fantastic Four when they went to the Moons' Blue area. Here they met the Watcher who was going to wipe their memories when Red Ghost had entered the Blue area of the moon with his team of super apes. They attacked the Thing and Uatu stopped the fight stating that the Fantastic Four would fight Red Ghost and his group of super apes. Uatu admired how the Fantastic Four fought and decided not to wipe their memories of their meeting.
He later warned them about the coming of Molecule Man who was given the ability to control matter after a lab accident. After his defeat the Watcher sent him to another dimension where time moved much faster there than in his normal universe, it also lowered his powers so he couldn't use is powers to escape.
During Reed and Sue's wedding he stopped a horde of super villains by bringing them to the blue area of the moon and then erasing their memories. He said that Reed and Sue could have their honeymoon on the Blue area of the Moon, he also told them that they would be the only people in the galaxy who he would not be watching that night.
When Galactus first came to Earth he tried to hide it from him, but when that failed he helped the Human Torch find the Ultimate Nullifier to defeat him, breaking his oath of non-interference.
Uatu disgraced himself by physically opposing Captain Marvel after taking sides with the lunatic legion, a team of Mar-Vell hating Krees. For this Uatu was put on trial by his own people for interfering in earth affairs. He was set free because he promised that he wouldn't interfere again.
Uatu has also collaborated with the mutant team, X-Men, and he seems to have a history with Apocalypse, as they are seen discussing about the conflict between the heroes and Onslaught.
With the coming of Abraxas, the Fantastic Four visited Uatu on the Moon only to find that his equipment was off and Uatu himself was suffering from memory loss. Eventually, Uatu slipped into a coma. The heroes of Earth soon learned that Abraxas was after the Watcher because he was the only being to know the secret location of the Ultimate Nullifier. The Silver Surfer used his powers to transport Uatu far from Abraxas' reach, but at the cost of his own life. After Abraxas' defeat, the universe was restored to it's normal state, as was the Watcher.
His recent appearances with the heroes was when he witnessed the wedding of Black Panther and Storm. It had been said that if the Watcher is witnessing an event, it means that this event is a very important moment. He also told the newlyweds that their children have a very important destiny ahead of them.
During the Civil War, he came to Doctor Strange and asked about the coming conflict and why he hadn't use his powers to stop the war. Strange answered that he doesn't take sides and that both sides of the war are both right and wrong in some ways, and he stated that he will pray for the least amount of blood being shed after the war. Uatu reflects on this.
Uatu broke his deal of non-interference yet again when Eternity was dying. He assisted the Fantastic Four and Doctor Strange in performing surgery on Eternity by transporting them the hero Gravity from Earth. He knew that Gravity could manipulate a fundamental force capable of saving Eternity, and with him all of reality.
He briefly appears in Issue 4 of Hulk, where he comes to Earth to stop Red Hulk but is swiftly knocked out with one punch by the Red Hulk and does not appear again.
When the Future Foundation are transported to Uatu's home by the Impossible Man, it is revealed that he has a girlfriend, Ulana, who is pregnant.
