Pyat has a strong dislike for Jews, and is often openly prejudiced towards them. To his dismay, Pyat is often mistaken for a Jew himself. He has a deep love for Russia, his birth place. Later in life, Colonel Pyat became Mrs. Cornelius's regular lover and life partner until her death in 1975. He is the main character of the Pyat Quartet, also known as the Between the Wars series, and is a frequently occuring character in the Cornelius Quartet.
Pyat is, of course, an incarnation of the Eternal Champion.
