Who were the baby boy twins in full house?
Jesse Katsopolis (portrayed by John Stamos) is Danny's brother-in-law, Pam's younger brother, making him the maternal uncle to DJ, Stephanie, and Michelle. Later in the series, he also becomes the spouse of Rebecca Donaldson, Danny's co-host on Wake Up, San Francisco, by whom he has two children, twin sons Nicholas and Alexander, better known as Nicky and Alex. The character underwent several name changes throughout the series' development and filming. He was originally named Adam Cochran during production, though this was ultimately changed to Jesse, at Stamos' request. Later, producers changed his last name from Cochran to one of Greek origin, to Katsopolis, also at the request of Stamos, who is Greek American. Finally, in the fifth season, it is revealed that Jesse was originally named Hermes, after his great-grandfather, but his mother changed it to Jesse at his request after he entered primary school, as his peers bullied him for his name.

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.
