Matt Sloan

Matt Sloan was a mortal and the school bully at Meriwether College Prep. He was neither big or strong but acted like he was. According to Percy, "he had eyes like a pit bull, and shaggy black hair, and he always dressed in expensive but sloppy clothes." One of his front teeth was chipped from an experience between him and his father's Porshe.

During the Language exam at the end of the year (where the students were left unsupervised for an hour to see if they understood the book The Lord of the Flies) he constructed many "activities," including a wedgie contest between the seventh and eighth grade, two pebble fights, and a full-tackle basketball game. When trying to give a wedgie to Tyson, unaware that he was a Cyclops, Tyson swatted him away too hard making him fly fifteen feet and getting him tangled in the tire swing. He unwittingly recruited some Laistrygonian giants that he mistook for visiting students to his dodgeball team and when the gym was destroyed, he told police officials that Percy was responsible for the explosion, something the teacher agreed to as he had been reading the paper and most likely didn't know what he had just agreed with.
