“Money talks, I listen!”
- ―Flintheart Glomgold[src]
Flintheart Glomgold is Scrooge McDuck's arch-nemesis and business rival, primarily because of their long-lasting feud concerning which of the them deserves the title of "World's Richest Duck". Glomgold is jealous of Scrooge's wealth and desperately wants to obtain the title, but is usually referred to as "World's Second Richest Duck". He was created by Disney Legend Carl Barks, and made his first appearance in Barks' 1956 comic The Second-Richest Duck (Uncle Scrooge#15).
Flintheart will attempt any possible underhanded deed in order to defeat Scrooge and occasionally hires such thugs as the Beagle Boys to do his dirty work.
Glomgold returns in the rebooted DuckTales as an antagonist and, once again, Scrooge's sworn enemy. He is aggressive and obsessive, even claiming to be more Scottish than Scrooge. The creators have indicated that this version of Glomgold has become determined to outclass Scrooge in every category, as an in-joke to the character originally being South African and changed to Scottish for the 1987 series.This incarnation of Glomgold is also rather hefty in weight, compared to his previous appearances. In the episode "The Infernal Internship of Mark Beaks!", Glomgold's beard is revealed to be false. He first appears in "Woo-oo!", where he seeks to become the world's richest duck by acquiring the jewel of Atlantis. He inadvertently grabs a cursed gem by mistake and is dragged off by a giant squid.
