Past
In his youth, Duke Baloney was a poor shoe-shine who lived in South Africa

Season 1
In the pilot episode "Woo-oo!", Webby Vanderquack briefly mentions Glomgold and Ma Beagle upon meeting Huey, Dewey and Louie. Later, Glomgold fully appears when it is revealed that Donald Duck is applying for a job at Glomgold Industries. He hires Donald to be a sailor instead of an accountant, asking him what he knows about Atlantis.

Later, Glomgold talks to Donald, Gabby McStaberson and Hack and Slash Smashnikoff about their mission to steal the Jewel of Atlantis and make him the richest duck in the world. After Scrooge McDuck and Huey, Dewy and Louie unknowingly make a stop on Glomgold's boat for a bathroom break, Glomgold plots to follow his rival to the jewel and steal it from him, but when Donald says that he's going to kill his nephews for not listening to him, Glomgold takes his statement literally. Upon reaching and entering Atlantis, Glomgold tries to have Gabby kill Scrooge's group with throwing daggers, although Donald "accidentally" foils this and covers it up by stating that they should wait and torture the group later, an idea that pleases Glomgold.

Donald then strays away from the group under the excuse of needing to go to the bathroom and ends up saving Dewy from a booby trap, although his actions end up leading Glomgold to a short cut, causing Glomgold to question why he even needed to hire his other minions. Upon reaching the Jewel, Glomgold proclaims himself as the Richest Duck in the World, only to be tackled by Scrooge, who is under the impression that Glomgold had captured Donald. After Donald explains himself, Glomgold reveals that he only hired Donald to use as a hostage in case Scrooge tried to stop him, escaping and leaving Scrooge, Donald and Dewy to drown in the slowly filling room.

Upon encountering Huey, Louie, Webby and Launchpad, Glomgold has his minions fight them while he escaped with the Jewel, also betraying them and leaving them to die when he tries to destroy the sunken city. Glomgold then returns to land and claims to be the richest duck in the world to the press, only for Scrooge to appear with the real Jewel of Atlantis and upstage him, stating that the one Glomgold has is cursed. Enraged, Glomgold shouts at Scrooge, only to be grabbed and taken away by a Kracken.

In "The Great Dime Chase!", Glomgold makes a cameo appearance as a guest on the TV series Ottoman Empire, where he is seen complaining and making unreasonable demands to the hosts.

In "The Infernal Internship of Mark Beaks!", Glomgold and Scrooge engage in a "vision based battle of will" (or, as Dewey puts it, a staring contest), in Duckberg's Billionaire Club. Glomgold and Scrooge are soon joined in the club by soon-to-be billionaire Mark Beaks, who annoys the both of them with his arrogant attitude and a remix of bagpipe music. Soon after Beaks leaves, Scrooge and Glomgold decide to form a temporary alliance to stop him from joining the Billionaire's Club.

The next day, Scrooge returns to the club where Glomgold, who stayed there overnight, has put together a slideshow detailing the plan he formulated to get rid of Beaks. After an overly long "Declaration of Hatred" speech, Glomgold explains his plan to Scrooge: they will invite Beaks to a Billionaires Convention on a yacht, and then not show up, driving Beaks to forget his sorrows at the buffet table, which would make him distracted enough to not realize that the yacht was being sent into an active volcano. Beaks would then become so hot he would jump into the yacht's pool, which is shark infested, the sharks driving Beaks to forget he is in a volcano and jump off the yacht in fear. Scrooge criticizes Glomgold's plan, pointing out that they were only supposed to prevent Beaks from joining the club, not kill him, and rolls his eyes as Glomgold moves on to the "really complicated" part of his plan.

Later, Glomgold attempts to explain his plan again after Scrooge questions why they need a stuffed rabbit, resulting in the latter discovering another slideshow detailing how Glomgold plans to betray him. Glomgold futilely attempts to explain himself, and after being nearly chopped in half by an axe, Scrooge realizes that he wasted the day obsessing over someone he doesn't like, much like Glomgold does, and leaves. At the end of the episode, Glomgold, disguised as a mailman, gives Beaks an invitation to the Billionaires Convention and starts implicating his plan.

Personality
Glomgold is about as wealthy as he is determined and focused on defeating Scrooge and usurping his position as the richest duck in the world. In fact, unlike other depictions of Glomgold, this version's main motivation is his total obsession with either killing or beating Scrooge, and thus he puts less focus on scheming up ways to make money and more on devising death traps and ways to befall his nemesis. He makes no attempt to hide his goals unless he is pretending to be on Scrooge's side (and even then, he doesn't do a very good job), and is bold enough to try and blow up Scrooge's office on live television. He even claims that trying to kill Scrooge is his "whole thing"; implying that he really doesn't have much other motivation in life.

Outside of trying to outright kill Scrooge, Glomgold is concerned with beating him at just about anything, be it treasure hunting, sports, and even the pursuit of love and happiness. He takes great pride in even the most minor of victories, like when Scrooge lets him win a coin toss in "The Missing inks of Moorshire!", and thinks that his accomplishments will anger or invoke the jealousy of his rival. This is yet again seen in the aforementioned episode when he hires Louie as his caddie, claiming Scrooge's own flesh and blood has turned against him, and in "The Golden Lagoon of White Agony Plains!", where he tries to make Scrooge envious by getting together with his ex-girlfriend Goldie O' Gilt (excessively ignorant to the fact that she doesn't like him).

In spite of his failures, Glomgold is arrogant enough to believe that he has the upper hand at any given moment, and that this may lead to Scrooge's downfall. Thus, he is totally enraged whenever his plot are foiled or when Scrooge outsmarts him, as well as whenever he loses or appears to be losing. He hates being ignored and treated like a third wheel, too, and buts into a situation whenever he can if he feels attention is being drawn away from him. His own narcissism is shown to totally warp his own perception of himself, as, in all of his paraphernalia, plans, and even his own mind, he views himself as tall, handsome and attractive, while Scrooge is often left poor and defeated by him. He also frequently concocts excessively long speeches to exemplify his victory, which usually just end up boring Scrooge and his other enemies.

Despite his incompetence and overconfidence, Glomgold can be quite clever and resourceful, like in "Woo-oo!", where he hires Donald Duck to work for him only to use him as a hostage when Scrooge gains the upper hand. In the same episode, he also turns on his own henchmen and leaves them to drown in Atlantis, proving his claims of his employees being the greatest treasure of all nothing but a farce. Also, despite his hatred of Scrooge, he does have genuine respect for the latter's butler, Duckworth, and remembers him quite fondly.

Trivia

 * In the "Dewey Dew-Night" online shorts, there is a recurring joke in which Dewey apologizes to Glomgold for bumping him off the show, accompanied by the latter shouting "What?!" in response.
