Lambo is a 5-year-old hitman who originally came to Japan with the intent of killing Reborn. He is a spoiled and cowardly child who takes candy from everyone; it has been said that he never brushes his teeth. Lambo is the youngest guardian and each Famiglia member takes turns caring for him, with the exceptions of Hayato Gokudera and Reborn who consider him to be overly annoying and stupid, referring to him as stupid cow. He was previously a Bovino Famiglia mafioso and is currently the 10th generation Lightning Vongola Guardian. He thinks of himself as a good hitman and refers to himself in third person as "Lambo-san."
At the age of five, Lambo's hair was styled into a massive afro, wearing his horns on both sides of his head, his outfit covers most of his body, consisting of a cowhide pattern and tail.
At the age of fifteen, Lambo's hair becomes much more contained, his right eye usually remains closed now that he's older, his outfit consists of a black jacket with a cowhide pattern collar, which is somewhat opened and leaves the upper half of his chest out, he wears a necklace with a bull pendant, beige pants, and sandals.
A twenty five year old version of Lambo briefly appears during the Varia Arc. His hair was somewhat longer and had many braids in his hair, he wears a brown coat with beige fur, a white shirt, a black necklace that resembles a shark tooth, black fingerless gloves, his brown belt had a gray buckle in a horn shape with two other belts around his belt, his pants were black and he wore brown shoes.
Lambo is considered annoying by most of the people he meets, but by his fellow Guardians, he is also considered as someone dear to them. He is shown to be very self-confident and views himself with high regards, but he often ends up crying over small things. He is constantly shown picking his nose and getting into trouble. He is highly incompetent in assassination, and makes silly mistakes to the point of being either pitiful or just looked down upon. When Lambo is surprised, he normally expresses his shock by shouting, "Gyupaa!" 15 years old Lambo is still the crybaby he was when he was younger, but can become determined to face his fears for his friends and loved ones, similar to how 5 years old Lambo had recently been shown capable of doing, though only for the sake of being with Tsuna's mother, Nana Sawada. In his brief appearance, 25 years old Lambo is shown to be more serious, unwilling to cry upon seeing the faces he had not seen in a long time. Both 5 year old and 15 year old Lambo have been shown to resemble the first generation Lightning Guardian, Lampow, in terms of personality, but the two show little respect for each other.
