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 Kidd and Luffy's crews, in the face of a daunting Marine attack.

Alongside the rest of his crew Penguin fought against one the Pacifista 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.
