Petyr Frey, also called Petyr Pimple, is a member of House Frey and is the youngest of Ser Ryman Frey's three sons. His elder brothers are Edwyn and Walder Frey. Petyr is married to Mylenda Caron and they have one daughter Perra Frey.
Petyr's face is covered in warts and pimples (thus the reason for his nickname), but even without them he is not a handsome man.
A Storm of Swords
Petyr, together with his brother "Black" Walder Frey, and his father, Ser Ryman Frey, are sent to greet Robb Stark's arrival at the Twins for the wedding of Lord Edmure Tully and Roslin Frey. Robb's direwolf, Grey Wind, tries to attack them, scaring the greeters' horses and dropping Petyr into the mud. During the Red Wedding he passes out drunk trying to compete with Greatjon Umber.
After the Red Wedding, Petyr is captured by the brotherhood without banners while wandering around with some camp followers and is kept for a ransom of one hundred gold pieces. Merrett Frey volunteers to pay the ransom at Oldstones, hoping to gain favor with Ryman's branch of House Frey and not be thrown out of the Twins when Lord Walder Frey finally dies. Merrett is shown Petyr's hanged body, however, and Merrett is himself hanged soon after for his participation in the Red Wedding.
