Nanpario Pengino

Nanpario Pengino (voiced by Shintaro Ohata) is a penguin-themed Gangler Monster and the only one who's equipped with no treasure of the Lupin Collection, but he's the main antagonist of 2018 TV special called Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger ~GIRLFRIENDS ARMY~.

History
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.
