Penguin

Penguin is one of the members of the Heart Pirates. His name was revealed in SBS Volume 62.

Appearance
Penguin is an average sized lean man. Like most of the Heart Pirates he wears a beige overall, with their Jolly Roger displayed on the back and the chest pocket, as well as brown boots. He wears a black cap with a yellow brim, a red pompon on top and his name displayed on the front.

Abilities and Powers
He resisted the burst of Haki released by Silvers Rayleigh in the Human Auction House.

Sabaody Archipelago Arc
After a long voyage following one of the Log Pose routes of the Grand Line, Law and his crew came to the Sabaody Archipelago to prepare themselves for the New World. He was seen standing behind his captain as he talked to X Drake.

He is later seen with his captain at the Human Auctioning House, to observe the auction taking place. After interruptions by Luffy, the Heart Pirates found themselves fighting to escape, alongside Eustass Kid's and Luffy's crews, in the face of a daunting Marine attack.

Alongside the rest of his crew Penguin fought against one of the Pacifistas; though the outcome of this battle wasn't seen they eventually managed to escape.

Marineford Arc
During the Whitebeard War, the Heart Pirates and Penguin were initially present on the Sabaody Archipelago where the broadcast of Ace's execution was being shown. He was presumably watching the events at Marineford unfold, along with the Supernovas and they set sail immediately after the broadcast was cut. He can be seen on the Heart Pirates submarine as they emerge towards the end of the war to pick up a critically injured Luffy and Jinbe.

Post-War Arc
Penguin lands on Amazon Lily alongside the rest of his crew and is seen trying to keep Luffy, maddened over the loss of his brother Ace, down so he doesn't injure himself further.

After Rayleigh arrives, the Heart Pirates leave Amazon Lily. Penguin expresses his disappointment about not getting a chance to see inside the all-female kingdom.

Later out in the open sea, Law explains about waiting for the right time to enter the New World. Law tells his crew to follow his orders so he can steal the proper throne. Penguin and his crew mates cheer on.
