40 Creepy Facts About The Black / Lestrange Family From Harry Potter
Padfoot is Not an Original Name
James, Sirius, Peter, and Remus all had codenames on the Marauder’s Map. James was Prongs, Sirius was Padfoot, Peter was Wormtail, and Remus was Mooney. Although Sirius’s nickname seems like a clever play on the fact that his animagus is a dog, it’s not quite that simple. In fact, the name Padfoot comes from English folklore, where it refers to a hellhound known as Black Shuck.
Given the way we’re introduced to Sirius’s animagus, that name seems entirely appropriate. This is a myth that centers on a big, black dog. It was the perfect nickname for Sirius’s other half, and it fits his human personality pretty well too.
