Sir X. Checker is a male anthropomorphic dog.


The elderly and sensible Sir X. Checker is a member of the Mintavian aristocracy and the country's royal treasurer. In 1982, he traveled to Duckburg to enlist the help of Scrooge McDuck and his gold-sensitive sense of smell to solve a particularly tricky counterfeiting problem. He then accompanied Scrooge throughout his investigations.
