When he was younger, he loved to bully Nate. However, in kindergarten he left, as he only came for a summer.
It has been guessed at that he might be British hence his name.
Breckenridge became a new student at P.S. 38, and Principal Nichols asks Nate Wright to be his 'buddy' and show him around the school. Breckenridge starts off as somewhat shy, and thinks Nate is his best friend. Nate thinks he remembers something about him, and is later revealed that his grandmother used to call him Bobby.
Nate then remembers that Bobby was a bully in his preschool. He yells at Breckenridge that he is not his buddy. He later forgives him and includes him on his scavenger hunt team, in the P.S. 38 centennial. He helps to find everything in the Scavenger Hunt, leading the team to victory, beating Gina's team for the second time, the first being in the Trivia Slam. It earned his nickname, B-dawg.
Included in the scavenger hunt, the last item needed for Nate's Non-Stoppers to complete the list was to make the school a better place. When the team was searching the storage, Breckenridge spots a painting that happened to be a Granny Peppers painting, which would bring the school a nice mural. This event caused Nate's team to be on the news and raised the school a lot of money, so they were able to do repairs, which seemed liked it, considering there was barely and damage in Big Nate Blasts Off.
His alter ego is a superhero named "Buddy Boy", as seen in Bud or Dud.
He is said to have the grip as a limp noodle and the impression that he will wet his pants. He has light brown hair and is the shortest known student at P.S. 38. He is always seen wearing circle shaped glasses similar to Francis.
