}}'''Sir X. Checker''' is a male anthropomorphic dog.
The elderly and sensible Sir X. Checker is a member of the [[Mintavia]]n 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.
==Behind the scenes==
The King only ever appeared in 1982 in ''[[The Counterfeit Caper]]''.
