Magica lives on the slopes of Mount Vesuvius, next to Naples, Italy. Her primary motivation is to steal Uncle Scrooge's Number One Dime and melt it in the fires of the volcano to turn it into a powerful magical amulet, capable of granting the Midas Touch to whoever wears it and allowing them to turn anything into gold.
Unlike other people who think the Number One Dime to be a lucky charm, Magica doesn't believe it to be the source of Scrooge's wealth, but Scrooge's wealth to be the source of the dime's powers, as she only tries to steal it from him because it's the first coin ever earned by the richest duck on Earth, and has been touched frequently by him.
Magica appears as the main villain of the reboot's first season, although she was first revealed at the end of "The Beagle Birthday Massacre!" This incarnation of Magica speaks with a British accent instead of a Russian accent, as well as having green-blue feathers (due to the effects of magic), slit slice-like pupils, and a more lanky design in a callback to her first appearance in the Cark Barks comic The Midas Touch.
In all of her appearances so far, a shadow Magica appears through the shadow of her niece Lena. Motivated by a personal scorn towards Scrooge and his family, Magica yearns to steal the Number One Dime, which Magica intends to use during a lunar eclipse to increase her power and have her vengeance. She forcefully enlists Lena into her scheme through the talisman Lena wears that allows Magica to control her. Although Lena is at odds with her aunt, she obeys Magica in order to achieve her freedom, and Magica constantly urges her to abandon her growing friendship towards Webby. When the eclipse begins to draw closer, Magica's power grows to the point she is able to possess Lena at the end of "The Other Bin of Scrooge McDuck!".
