Vergo

How Vergo joined the Tourney
"Demon Bamboo" Vergo was one of the four elite officers and the first to occupy the Heart seat of the Donquixote Pirates under the codename Corazon. He was a Marine vice admiral, and head of G-5, who made his first debut at Punk Hazard. Due to his duplicitous conduct and allegiances, he can be considered the secondary antagonist of the Punk Hazard Arc.

Under cover as Corazon, Vergo poses as a waiter at L'Amor restaurant in Southtown. His rude treatment of angry customers arouses suspicion of King.
