Baron Tamago is a combatant of the Big Mom Pirates, who originates from the Longleg Tribe. He and his partner Pekoms are responsible for collecting the monthly payment of sweets from Fishman Island in exchange for Big Mom's protection.
Tamago always uses French words like "bon" at the beginning of his sentences and "soir" and "s'il vous plaît" at the end of his sentences. He uses "bon" as a suffix and prefix, but mostly a suffix. He is polite and negotiable, as well as rather intelligent, as he saw exchanging the treasure for some extra time to make more candy to be perfectly acceptable. Tamago even offered to give the citizens more time until they could accomplish the task (although the time he gave them was clearly insufficient compared to the situation explained).
He even fully elaborated the protection Big Mom lent to Fishman Island in exchange for candy to the Straw Hats' "Monster Trio", along with the consequences of them failing to fulfilled their end of the bargain. Like most of Big Mom's subordinates, Tamago is afraid of her. In reference to his egg-theme, he refers to inexperienced people as "half boiled" and when people surprise him with their ignorance, he even calls them "raw". Tamago seems to dislike arrogance as shown when he admitted to be disgusted by Caribou after Pekoms noted that Logia users who thought themselves to be invincible did not tend to live long. Tamago, like many others in the crew, is responsible for collecting candy payments from the various islands under Big Mom's protection. He seems physically rather strong, in contrast to his disproportionate build, being able to easily lift Fishman Island's treasure that Luffy imparted him and Pekoms with. As a member of the Longleg Tribe, his long legs are considered to be the main point of his combat strength and at the same time, his weakness. He is seen carrying a pistol on his right hip, and a long cane similar to Brook's.
