AU where the triplets were separated from birth after Della’s out, but one of them gets stolen at birth by one of Scrooge’s sworn enemies. Dewey living with Scrooge, having fun with Webby, being a weirdo like her because of homemade education and an overprotecting uncle (but at least he has Webby). Huey is with Donald, he stills a Junior Woodchuck, he’s pretty much like normal Huey, but feels really empty. Louie’s the one with the villain but I can’t figure out with who. And being REALLY evil.

Let it be Rockerduck. I mean, he wouldn’t be actually evil, but it would be hilarious. 

And Louie would be a bit of a jerk but hey, freaking rich, because Rockerduck would spoil him.
