Penguin

Penguin is a member of the Heart Pirates. 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 His appearance after the timeskip is pretty much the same as before except the red pompom has now been replaced with a decoration that looks like a young emperor penguin, probably as a reference to his name.

In Wano, he wore a light blue yukata with the Heart Pirates' jolly roger on each side of the chest. He also carries a sword at his side. Like Shachi, he likes women and is loyal to his captain, Law. As a teenager, he was a bully who was prone to mocking people and picking fights. Penguin resisted the burst of Haki released by Silvers Rayleigh in the Human Auction House which shows that he has a strong will. In the anime, he has been seen using martial arts next to Shachi and is quite proficient at it. He was seen carrying a spear when defending Zou from Jack and his army. Later, he was shown using the same spear during the Onigashima raid. Before the raid, he was seen wielding a katana. On their way to the next island, the Heart Pirates were ambushed by the Blackbeard Pirates, who were in search of Road Poneglyphs. The attack damaged their submarine and infected the crew with the Feminization Disease; Penguin became infected and turned into a woman after clinging onto Shachi. After Law's Haki canceled out the transformation on his own body, the resulting antibodies spread through the crew, curing the infected. The submarine then surfaced at a nearby island, and the crew ran ashore and prepared to fight back against the Blackbeard Pirates. Law saved his crew from a mountain thrown by Jesus Burgess and then confronted Blackbeard directly.
