History
The Cosmic Tribunal were a collection of alien races in the distant reaches of space who decreed that humans were too war-like to continue and so sent the Adjudicator to destroy the Earth. After the Fantastic Four's many failed attempts to stop it, Mister Fantastic sent the Silver Surfer to unleash the Decimators on them to make the Adjudicator leave Earth. They were helpless to stop the onslaught of the Decimators and would have been wiped out had they not been rescued by the Fantastic Four and Galactus. Realizing not all of humanity was evil, they reversed their decision and allowed the Earth to remain untouched.[1]
