Peter Mason


P.S. 38


Nate Wright, Francis Pope, Teddy Ortiz


Probably 6 or 7



Peter Mason is a student at P.S. 38. He is in Mrs. Bigbee's first-grade class and is mainly known as Nate Wright's "book buddy" in school and being the only person Nate has ever babysat. He is very intelligent for his age (considering he is in the 1st grade), and reads at an above-college level and reads books like Flaubert and Sense and Sensibility.


Nate had the idea of a summer camp in 2006. Peter's mom signed him up for it, but only because his mother missed the deadline for Robotic's camp. This started to make Peter furious at Nate and his mom. The two did a nature walk, which had no nature except Spitsy, a dog.

Then, the scavenger hunt was to force Peter into buying Nate food. He finally got Peter occupied with a New York Times Crossword Puzzle, but he solved it instantly. They had a "campfire" at 10:30 AM which was just an imaginary fire.

They played water sports, but it was only Marco Polo in an inflatable pool. It's also revealed later that they played "Duck Duck Goose" together. Peter was the first and only member of the summer camp. This ultimately leads to Peter being angry at being Nate's book buddy. Nate was later hired by Peter's mother to bring him to trick or treating and to the beach later.

At the beach, Peter ran out of sunscreen. Nate gave him his own sunscreen, but it contained cocoa butter, and it was revealed that Peter is allergic to cocoa butter. Nate then came up with another came that involved Peter not telling his mom about that.

Nate once hired Peter to help him study for his social study exams. Nate ended up getting 99%; he got every question right, yet he forgot to write his name.

Peter has also been a wacky plot twist during the fact town smackdown of 2014(Francis VS Gina). Francis got a question wrong, then suddenly Peter appeared. Gina proceeded to answer the next question but he answered that question so Gina could not result in a tie.


Peter has brown hair and wears small round glasses. Over the years, Peter had grown quite a bit fatter than before.


Nate Wright

Nate is usually pretty friendly to him, not really noticing that Peter would rather he not be around. Peter sometimes screams when he hears Nate yell, “Peter, my boy!”

Unidentified female classmate

All that is known is that a girl in his class is in love with him. Peter seems uncomfortable with her affection, freaking out when she spots him and trying not to make eye contact with her in class.


  • Peter is a minor character in the series. His speech impediment is similar to Nick Blonsky's as seen in Big Nate: Flips Out.
  • Every time Peter says an "s" word, it always comes out as "shh", and he spits as well.
