This may be Mr McDuck's Mansion but it's my house so... my house rules.
Bentina Beakley, usually referred to as Mrs. Beakley, is a big-boned anthropomorphic duck and the one of the eight main characters of DuckTales.
Mrs. Beakley is Webby's grandmother and Scrooge's no-nonsense house keeper, bodyguard, and closest confidant. Beakley has a mysterious past and particular set of skills that goes beyond vacuming and doing windows. She's trained in every martial art and action tactics. Although she often calls Scrooge out, she's the only person he really trusts.
Beakley is fierce and fearless housekeeper who is very orderly when keeping the mansion clean, organized and safe. She takes this very seriously as show in the episode Daytrip of Doom! She was very protective over Webby but after the event in Woo-oo! she allows her to go on adventures with Scrooge, Donald, Launchpad, and the nephews. Mrs. Beakley has a dry sarcastic wit, and impressive physical feats. She often times takes safety as the first priority in cautious situations. This can be shown when in episodes like The Last Crash of the Sunchaser!, she continuously attempted to convince Scrooge about the safety options during their predicament, even though Scrooge's arrogance rejected all the options nevertheless.
Years prior to DuckTales, Beakley was once a member of S.H.U.S.H. as Agent 22. She was assigned Scrooge McDuck as a partner to procure a page from the Book of Castle Dunwyn. At the auction, Black Heron had stolen the page and the two chased her to an island base. Beakley was taken captive while Black Heron announced she had made bouncing juice to prepare for world domination. As Scrooge came to her rescue, Beakley drank the juice and eventually destroyed the formula page. She then fought Black Heron starting a fire that amputated the F.O.W.L. chemist's arm. Escaping the fire, Beakley decided to stay in Scrooge's household.
She also attended McDuck Enterprises' first annual Christmas Party dancing with the guests.
After Duckworth died from unknown causes, Beakley succeeded him as housekeeper of McDuck Manor.
Enhanced Strength: As shown in Nothing Can Stop Della Duck!, Mrs. Beasley possesses supernatural amounts of strength, being able to lift a chandelier something Della was unable to do. Mrs. Beakley presumably obtained her immense strength from training as a secret agent for S.H.U.S.H. as Agent 22.
Skilled hand-to-hand combatant: Due to being a former secret agent, Mrs. Beakley has received years of hand-to-hand combat training and is quite a formidable foe to face.
Master martial artist: Due to being a former secret agent, Mrs. Beakley has received years of martial arts training and thus is a master in it.
Expert Tactician: Mrs. Beakley is a skilled tactician, able to come up with plans to achieve the best outcome, like she did on missions as a secret agent.
Mrs. Beakley is Scrooge's no-nonsense house keeper, bodyguard, and closest confidant. She takes her job seriously and professionally yet as his employee she is very honest and straight-forward. Though is still polite and respectful, and looks out for him and his well being. She and Scrooge also used to be partners while Beakley was working under the S.H.U.S.H. organization. Their first ever mission together was when they attempted to stop a spy working under F.O.W.L., known as Black Heron, from creating an ancient potion enhancing the abilities to make super soldiers.
Donald Duck first met Mrs. Beakley at the end of Woo-oo! when Beakley talked to her granddaughter, Webby and allowed her to continue to go on adventures with Scrooge. Donald who watched this, then gave his nephews permission to continue to go on adventures with Scrooge. In Daytrip of Doom! Donald and Beakley got into a fight over house rules. Later Beakley got onto Donald about breaking fire laws, and using up the water bill, causing Donald to order multiple generators for his boat, and Beakley making the remark "He is going to kill himself," and afterwards jokingly laughed. Beakley watched Donald set his boat on fire, and the whole time just sipped her tea. Their first time working together wasn't until Donald showed her the ransom note that Beagle Boys had tossed at him. Later at the end of the episode Donald and Beakley were talking, and seemed to be getting along better then before.
In The Shadow War!, Beakley revealed that the loss of Della was the hardest blow to Scrooge that he locked himself away from everyone else. In Nothing Can Stop Della Duck!, Beakley meets with Della who recognized her as Agent 22 before she succeeded Duckworth. So far, Beakley cleaned up after Della's attempted shield-surfing stunt with her sons reminding her she is used to cleaning up after children. Beakley is worried that Della is having difficulty adjusting to the family's current way of life, that is until Della saves the family from the rampaging Gilded Man.
