Fabio (ファビオ, Fabio) was the seventh boss of the Vongola Famiglia. It was said that he had the weakest Flame out of all the Vongola Bosses, and because of this, he created the First Dying Will Gun. With this Gun, he could store his Flame in it and release it as a more powerful and condensed energy. He used Dying Will Bullets as ammo and used them to store his Flames within them. This Weapon and Technique is imitated by Xanxus in the Ring Conflict against Tsuna, as it is believed to be of extreme power. He first appears along with the other previous Bosses of the Vongola. In a small Vongola family tree, he is shown to be the father of Daniela, a.k.a. Vongola VIII.
Fabio's most noticeable characteristic amongst the ten Vongola bosses is his tall black hat. He wears a black suit with a white dress shirt. He has a mustache.
