Vongola Primo and his Guardians were the first-generation members and founders of the Vongola Famiglia. The Famiglia initially started as a vigilante group to protect townspeople at the times when the law could not protect them from crimes.
Giotto's group stands out among the families of the other generations thanks to being made up of individuals from the most diverse backgrounds, including a soldier, a cleric, a member of royalty, and a rival mafioso. This was due to the peculiar character of the first-generation boss, who would welcome anyone that he took a liking to into his Famiglia.
All members carry a special watch made by Talbot, whom Giotto requested to make it to symbolize their friendship. Numbers and messages are engraved beneath the covers of each pocket watch. Giotto stated that the numbers were based on the name "Primo" that the Guardians gave to Giotto.
- There are a number of similarities in both appearance and personality between the members of the first generation family and their correspondents in the tenth generation Boss and Guardians.
