Brocco has dark, curly hair worn in an afro taper, white, tripartite eyebrows, and a sharp jawline. Two long, parallel scars run horizontally across his face at the height of his cheekbones. In his first appearance, he wore a leopard-skin pelt or robe.
Due to not being an official child of the King of the 卡丁帝國, Brocco received two scars on his face as soon as he was born and was allowed to live under the condition that he never appear in public or concern himself with politics.
Brocco boards the B‧W1號 and resides in the VIP area of Tier 1. On the fourth day of voyage, he discovers through his Underboss that the Phantom Troupe is on the ship and currently on Tier 5. He phones his half-brother and head of the Xi-Yu Family, Onior, to inform him. Onior estimates the Phantom Troupe to be a potential source of imbalance, and Brocco convenes they lack the etiquette fitting those in power, commenting they could not fit even in Meteor City and will be difficult to control. He reveals that even some of his underlings admire them. At Onior's suggestion, the two agree to let the Heil-Ly Family and the Spiders destroy each other, taking care to control when they will do so. Brocco then summons his Underboss Ken'i and orders him to find Hisoka before the Phantom Troupe does.
As the Boss of the Cha-R Family, Brocco commands one of the three most powerful forces of the Kakin underground and has authority over a number of underlings. His mafia faction is supported by Prince 路茲路斯and controls Tier 5 of the Black Whale and all commodities stored there.
- Like his half-brothers, Brocco is named after a vegetable: in his case, the broccoli, of which his hairstyle is also reminiscent.
