As a Watcher, the character possesses a number of superhuman abilities, including strength, speed, agility, and durability. He also has access to advanced technology, including a number of powerful weapons and gadgets. Despite his powerful abilities, the Watcher is bound by his oath of non-interference, and he is not allowed to use his powers to directly interfere in the affairs of other beings. However, he has been known to bend or even break this oath on occasion, when he believes that it is necessary to prevent great harm or destruction. Throughout his long and storied career, the Watcher has observed and recorded countless events in the Marvel Universe, including the rise and fall of civilizations, the births and deaths of heroes and villains, and the struggles of ordinary people.
