Grandpappy Beagle is the grandfather of Ma Beagle in DuckTales. Prior to the series, he apparently stole the deed to Duckburg only to lose it to Scrooge McDuck, thus inciting the vendetta of Ma and the Beagle Boys against Scrooge.
He makes his first physical appearance in the season 2 episode Last Christmas!
In Last Christmas!, Grandpappy appears alongside his three great-grandchildren, Babyface, Bankjob and Bugle to rob past Scrooge's Christmas party when present Scrooge travels back in time to relive past Christmases.
- He is presumably based on the character of Blackheart Beagle, also referred to as Grandpa Beagle, from the Scrooge McDuck comics.
