who plays nicky and alex in full house
List of Full House and Fuller House characters Nicholas "Nicky" and Alexander "Alex" Katsopolis, (played by Daniel and Kevin Renteria as babies during season 5; Blake and Dylan Tuomy-Wilhoit as toddlers for seasons 6â€“8) are the twin sons of Jesse and Becky Katsopolis. The two were born in the season five episode "Happy Birthday, Babies," on the date of Michelle's fifth birthday. Becky named Alex after a high school teacher who inspired her to venture into a career in journalism, while Jesse chose to name Nicky after his father, for giving him great hair. They have strawberry-blond hair and are fun-loving toddlers, with minor distinctions between them. Nicky is more quiet and sweet, while Alex is more outspoken and mischievous. They often repeat each other's words.
List of Full House and Fuller House characters 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, husband of Rebecca Donaldson and father of twin sons Nicky and Alex. Born Hermes Katsopolis (as revealed in the season five episode "The Legend of Ranger Joe"), he was named after his great-grandfather, who in turn is named after the Greek god of swiftness. However, 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.
