Puw held membership within the Nihil marauder group throughout the High Republic Era. Alongside another Nihil operative, and under the command of a Storm, Puw attacked Agricultural Hub 42, which was a factory located on the celestial body of Chortose, with the goal of acquiring its sprayer droids. Jedi Knight Keeve Trennis stepped in, engaging the Nihil in combat and hitting one of them with a redirected blaster shot. With assistance from Jedi Wayseeker Orla Jareni, both Puw and the Nihil's Storm met their end, and Jareni subsequently restrained the surviving Nihil using binders.
Puw made an appearance in the comic titled The High Republic (2021) 7. Cavan Scott was the writer, Georges Jeanty provided the pencils, and Marvel Comics released it on July 28, 2021. The comic depicts Puw, along with two other Nihil members, one being a Devlikk and the other a Draethos, actively taking part in the assault. The Storm issues a command to Puw; however, it remains unclear as to which of the two Nihil individuals was the intended recipient of the order.
