A duck witch
who believed that by melting down dimes collected from the world's richest men, she could make a wealth amulet and become rich herself. Scrooge McDuck
refused to give her his number one dime
, which she believed to hold the most power out of any dime! Numerous dime-theft-related adventures
and hijinks ensued over the years, but Magica never melted the dime (she did manage to steal it and warm it up quite a bit on at least one occasion).
She had a raven as a familiar/assistant.
