 In the first season of Glee , Karofsky appears in five episodes . He is a jock and a bully , initially a member of the McKinley High hockey team . He is first seen in the episode " Mash @-@ Up " , where he slushies football captain Finn Hudson ( Cory Monteith ) . He reappears in " Mattress " , teamed with football player Azimio ( James Earl ) , and writes on Finn 's face with black markers to demonstrate how they will deface the glee club 's yearbook photo , which Karofsky does at the end of the episode . By " Theatricality " he is on the football team with Azimio , and they shove Kurt Hummel ( Chris Colfer ) and Tina Cohen @-@ Chang ( Jenna Ushkowitz ) against lockers for wearing Lady Gaga costumes — part of a glee club assignment — around school .
