The Grand Mogul (full name revealed as Philodemus Gentlefogg and Bertie McGoose) is the most frequently seen adult chief of the Junior Woodchucks. Despite other chiefs being depicted as dogfaces, the Grand Mogul has a bill. A running gag about the character is that "Mogul" (or another one of his countless pompous titles) is an acronym with a different meaning each time.
- In the Junior Woodchucks comic Let Sleeping Bones Lie (written by Carl Barks, published in Uncle Scrooge #358), the Grand Mogul's full name is given as Philodemus Gentlefogg.
- While it is likely that the Grand Mogul is a Goose (due to his full name being specified as Bertie McGoose in Italian Disney comics), it is unknown to which species he belongs.
- In Carl Barks' The Hound of the Whiskervilles (Uncle Scrooge #29), Scrooge briefly refers to a group of clansmen as members of the "Clan McGoose".
