Nanpario Pengino is a penguin-themed Gangler Monster and the only one who is equipped with no treasure of the Lupin Collection, but he is the main antagonist of 2018 TV special Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger ~GIRLFRIENDS ARMY~.
Nanpario Pengino's head is a green and pink knight penguin helmet with red hair, his body is green and pink armor like body with a Gangler safe on it, the arms are white green and pink skeleton arms, the hands are green, his pants are a dark pink color, his pink and grey feet look like penguin feet, his overall appearance looks like a medieval knight, his weapon the Long Uo Sword is a gray and gold fish shaped long sword that looks like a fish eating a cross.
A monster without a treasure, he appeared in an alley fighting Lupin Yellow for a brief moment before having his safe (which his password is 7-8-0) easily opened by Lupin Yellow, only to reveal that he had nothing inside.
The arrival of Patren-3gou and a little girl, Yuu prompted him to fight both rangers. He then stole Yuu's plush doll and placed it inside his safe and ran off.
When Umika and Tsukasa work together to lure him into an area using Tsukasa's prized plush collection, they take back the plush doll and destroyed Nanpario.
