The Watchers are powerful beings. They possess incrediable technology and believed that it was their duty to protect the universe from harm. The Watchers gave nuclear technology to a race of aliens but this race of aliens used the nuclear technology for war. The Watchers were very disappointed and vowed that they would never interfere with any events and to just observe and record.

The Watchers often came into conflict with the Celestials because of their different way of judgment. The Celestials believed that if the race couldn't keep up with their genetic standards, they would use force to seal the planet and give the good people a chance ro reform. The Watchers believed in just observing and recording and not just kill an entire race because they didn'y reach the Celestial's standards.
