Alberto Molina is Vicita Molina's older brother and one of Arthur's new neighbors in the show, Arthur. He has became a character on the Arthur episode "Arthur and Los Vecinos", when his family moved to Elwood City following the departure of Mr. Sipple.
Alberto practices kendo in his spare time, and even enjoys reading El Conejo Bionico, which is the Spanish version of Bionic Bunny, of whom he is a big fan. In the Arthur episode "To Tibble the Truth", Alberto's Bionic Bunny/El Conejo Bionico action figure got thrown out the window by the Tibbles and Alberto wanted them to start telling the truth to people. After Tommy and Timmy become too honest and hurt peoples' feelings, Alberto tells them to tell the truth, but be nice about it.
He also owns a soccer ball, "El Boomerang", signed by his favorite Ecuadorian football (soccer) player, Juan Carlos Salamanca. The soccer ball, after becoming lost at the park and confused with Francine's soccer ball, traveled around the world in a series of events in Season 14, but was eventually returned to him in "The Long Road Home" after Arthur's pen pal Adil finds it and mails it to Arthur. Arthur was then invited to Alberto's birthday party, and decides to give the ball to Alberto then. After it becomes lost by coincidence again, within the same episode, George returns to Elwood City on his walk from Crown City, kicks it, and the ball is returned to Alberto as it lands directly in his hands.
