Business Manningtonson is or was a man of unknown species from the 2017 Continuum.
According to certain accounts, individual is or was a businessman (as their rather over-the-top name should hint), and presumably a rival of Scrooge McDuck.
Behind the scenesEdit
According to Francisco Angones in Frank Angones and the Suspenders of Disbelief, the character of "a businessman named Business Manningtonson" was cut from DuckTales 2017 for time, with no plans to reintegrate him in future episodes. An allusion to Manningtonson remains in The Infernal Internship of Mark Beaks, where Dewey Duck makes up “Business Manningtonson” on the spot as part of an unconvincing excuse for slacking off — which would suggest Manningtonson's existence has been retconned away.
