Rhantom Plot is a very big criminal who works with Pete, and not just a minor villain but a criminal genius. He created by Floyd Gottfredson and he appear in italic comics until today. See here for ditails:
Also, adding so many new characters (only Manny and Lena, no Violet) is really boring. But if that was the case in 1987, only Carl Barks' characters should have remained since the series is based on his comics.
In italian comics, Huey, Louie and Dewey they have different personalities espesially in stories of Claudio Sarrone who puts different personalities on the nieces but also on all of Louie's form.
Ηowever, if you want to know I like the Beagle Boys, Launchpad and Doufus more in 1987. They are more funny.
Also, the good thing about the 2017 version is that they don't have any simplicity. Fantastic! Only Fantastic!
