Alexander "Alex" Katsopolis (born November 12, 1991) is a special guest character on Fuller House. He is a fictional character on Full House and Fuller House. He is the son of Jesse and Becky and identical twin brother of Nicky.

He is portrayed by Dylan Tuomy-Wilhoit.


He grew up in the house with the Tanner family. Becky got pregnant with Alex and his twin brother Nicky and had trouble breaking the news to Jesse. She tries to tell him in a candlelight dinner but Jesse was too happy to go on tour. Later she told him in a game of Pictionary. On Michelle's birthday they had the twins. In "Nicky and/or Alexander", Jesse mixes them up by taking off their booties and put Alex's booties on Nicky. Later he inks Alex's foot. Then Becky finds out.


Alex, much like Nicky, is a humorous and mischievous character. Throughout the seventh and eighth seasons, they caused trouble worth more than the two of them combined, let alone singular. They adore each other, which caused them to cling on each other until Jesse and Becky had them find their own personalities. They also were the focus of Jesse's attention and he tried to raise them the way that his own father never had, but it usually led to them overpowering him until Becky comes in with her motherly advice to him. Nevertheless, they are both still mischievous and cause much stress to their parents' lives.
