Nothing stops Della Duck!
Still kicking as much ass in her mid to late fifties as she has since... her birth pretty much- it's Della!
After Louie goes missing, the family spends years trying to find him. As time goes on and the kids get older and there's still no sign of Louie, her relationship with Huey grows more and more strained until one day he walks out with Dewey (reluctantly) following behind him.
Shattered by the loss of her family for the second time, Della throws herself into searching the world for the amulet that Louie's been trapped in.
Spending most of her time chasing leads and beating up anyone who gets in the way, she also juggles running back home in between to keep her brother, the SHUSH agent, from putting her kids behind bars.
Sure they run the biggest crime syndicate in Duckburg with operations reaching world wide- but they're HER kids damnit! And they're just trying to find Louie just like she is! She can fix it! She can!
She just needs to find Louie and she can piece her broken family back together in no time!
To bad that's a goal she's been trying to accomplish for 23 years...
