Allfather is a title that represents the highest authority of a particular organization. In DC Comics/Vertigo titles, the Allfather is the leader of a massive religious secret society known as The Grail. The purpose of The Grail is to protect the purity of the bloodline of Jesus Christ, even though most of the world believed that Christ died without siring children. In the modern era, D'Aronique was the 112th Allfather of The Grail. When D'Aronique died after falling out of a helicopter, his successor was Herr Helmut Starr.
In Marvel Comics continuity, Allfather is the title used by the king of the Nine Realms, which is headquartered in the Golden City of Asgard. The most well-known of the Allfathers was Odin Borson. He was often addressed by the title Allfather Odin. When Odin died, his son Thor Odinson became Allfather.
