This is a list of the characters from the American television sitcom Full House. The series ran for eight seasons on ABC from September 22, 1987 to May 23, 1995.
Jesse Katsopolis (portrayed by John Stamos; the character's last name in season one was Cochran, but was changed reportedly due to John Stamos wanting his character to better reflect his Greek heritage) is Danny's brother-in-law, Pam's younger brother and husband to Rebecca Donaldson and father to twins Nicky and Alex. Born Hermes Katsopolis (as revealed in the season 5 episode "The Legend of Ranger Joe", and was named after his great-grandfather, who in turn is named after the Greek god of swiftness), he did not like his birth name as other kids teased him for it; so when he was in kindergarten, he begged his parents to have his name changed to Jesse, thinking that one had to have a "cool name" to be in the in-crowd. As an adult, he was more confident with his true name, telling the girls about the Greek god of speed and how his great-grandfather saved a village from a volcano, but still goes by Jesse. In contrast with Danny, Jesse is portrayed as being irresponsible most of the time, but occasionally serves as a responsible adult when a responsible adult is needed (such as when he discovers Stephanie's classmate is a child abuse victim in the season 6 episode "Silence is Not Golden"). Jesse is revealed as a high school dropout in season six's "Educating Jesse", though in an earlier plot (in season four's "One Last Kiss") about a high school reunion, he mentions not wearing his cap to his graduation because he did not want to mess up his hair.
