The Underworld is the whole system of connections, smuggling, and shady dealings which eludes the World Government’s control. It is mainly set in the New World.
This list is about all known Underworld Emperors:
#1 – DU FELD
Du Feld, known as the “God of Fortune”, is the “Loan Shark King”. As an emperor of the Underworld, Du Feld has strong degree of power within it. His importance is recognized by the Yonko Big Mom, who has invited him to her tea parties.
#2 – STUSSY
Stussy is an agent of CP-0. In her cover as an emperor of the Underworld, she operates under the epithet of the “Queen of the Pleasure District”.
Stussy seems to be good terms with Big Mom, whom she addresses casually as “Linlin”. However, since her status as a CP-0 agent has come to light, it appears Stussy was just using Big Mom to obtain the Tamatebako and even used Du Feld as a scapegoat to cover her tracks.
#3 – DRUG PECLO
Drug Peclo is the “Major Undertaker” and an emperor of the Underworld. As an emperor of the Underworld, Drug Peclo has a strong degree of power within it. His importance is recognized by the Yonko Big Mom, who has invited him to her tea parties.
#4 – MORGANS
“Big News” Morgans is the president of the World Economic Journal and one of the emperors of the Underworld.
Morgans is in charge of the World Economic Journal, giving him control over the newspaper and the information it gives to people. He has access to information not available to most people, as demonstrated by his knowledge of Big Mom’s recent acquisition of the Tamatebako and of her Soul Pocus technique.
His importance is recognized by the Yonko Big Mom, who invited him to a Tea Party. He also has deep bonds with the Germa, and his newspaper incidentally publishes a popular comic strip that features their army as its main antagonists.
#5 – GIBERSON
Giberson, known as “The Concealer”, is a veteran warehouseman and one of the emperors of the Underworld. He is important enough to be invited to the Yonko Big Mom’s tea parties. Despite the Charlotte Family revealing their treacherous plot to destroy the Vinsmoke Family, Giberson insensitively found Vinsmoke Judge’s crying and pleas to be amusing, and was not bothered by this act of betrayal (albeit not directed to him).
#6 – UMIT
“Deep Ocean Current” Umit is a shipping magnate and one of the emperors of the Underworld. Umit appears quite serious and angry, in contrast to the joy and amusement his fellow emperors show. He also was invited to the Yonko Big Mom’s tea parties.
