I have an idea in mind, but it will most likely be a fan story. There should be a villain in season 4 who will be an enemy not only to Scrooge McDuck and his family, but also to Lena and Magica. My character is Rico De Spell, Lena's evil twin brother or doppelganger, who is her complete opposite. Rico will initially appear as an ambiguous character, being an antihero, because it will turn out that he has been killing all the villains of Ducksburg (yes, he will be a murderer), and when it comes to Magica, he will take advantage of Lena. Soon, everyone will realize what a double game Rico has been playing, and everyone will try to stop him. Soon, it will happen that Poe De Spell is found... and Magica and Lena will find him (the former will ask the latter for help), although Lena initially did not believe her. The De Spell family will be reunited, but only briefly. All three magicians will unite to stop Rico. At some point, this might succeed momentarily, but Rico will unleash his true demonic potential and kill Poe de Spell before Magica's very eyes, declaring, "You wanted to create a child like you, a monster... so have one." After some time, Magica, in a despondent state, will find common ground with Lena and, using all her strength, stop Rico. Everyone who died at Rico's hands will be resurrected thanks to Lena's Friendship Magic, including Poe de Spell. After this, Magica will cease her evil deeds and go into hiding, finding common ground with the McDuck family and, most importantly, Lena.
