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 titles) is an acronym with a different meaning each time.Tony Strobl's 1968 Disney comic Surprise Party contains a flashback showing that the Grand Mogul used to be a Junior Woodchuck himself when he was younger.
- In the Junior Woodchucks comic Let Sleeping Bones Lie (written by Carl Barks), the Grand Mogul is fully named 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 unkown to which species he belongs.
- In the classic Disney comic The Hound of the Whiskervilles (first published in 1960), Scrooge briefly refers to a group of clansmen as members of the "Clan McGoose".
