Mervin Monroe - Gino

Gino, voiced by Tress MacNeille is Sideshow Bob and his wife Francescas' toddler son. He shares the same unusual hair style and hatred for Bart Simpson as his father. He first appears in the season 17 episode "The Italian Bob" when Sideshow Bob moved to Italy to start a new life, without anyone knowing, not even his own family, about his murderous history. That is, until Lisa became drunk at a feast and told the whole town everything, even though the Simpson family had promised not to mention anything since Bob fixed their car. Gino helped his parents try to kill the Simpsons at the Collosium, by running at them, shouting "Vendetta!" and brandishing a knife. Unfortunately, for him, they were saved by Krusty, who needed some people to help him smuggle antiquities. Gino makes his second appearance in the season 19 episode "Funeral for a Fiend", where it is mentioned that after leaving Italy, he and his parents toured around London for a while before sneaking into America on a train. He, and all of the other members of Bob's family played a part in a complicated plan to finish off Bart for good. However, they were foiled by Lisa Simpson and were arrested by Chief Wiggum.
