Despite this, the Watcher Uatu has revealed himself to the superhero team the Fantastic Four,[1] and aids them on several occasions against global threats such as the Molecule Man,[2] Galactus,[3] and the Overmind.[4] After blatant interference with the mission of the Kree soldier Mar-Vell, Uatu is put on trial by his own race, but is released on the provision that he never directly interfere again.[5]

Uatu is later banished by his race for aiding the Fantastic Four against the threat of his rogue nephew, Aron, the Renegade Watcher, who tries to destroy the universe.[6] The Dreaming Celestial later scans Uatu and learns the Watcher has broken his pact of non-interference almost 400 times.[7] The Celestial also reveals the Watchers, like the Celestials themselves, are servants of a concept called Fulcrum, with apparent consequences for interference.[7] (emphasis added)

Then he’ll appear to the Fantastic Four
(repeat)
To tell them he can Watch no more
But must get off his bum.

To warn them of impending doom
(repeat)
The FF need to swoop and zoom
With alacrity and aplomb.

When the team has cleaned Galactus’ clock
(repeat)
He’ll return to Watching cosmic rocks
Like tumblers in heaven’s lock
And remain forever mum.
