Ryugu Tamatebacco

Ryugu Tamatebacco (voiced by Kōzō Shioya) is an oarfish-themed Gangler Monster and is the main antagonist in episode 28 TV series called Kaitou Sentai Lupinranger VS Keisatsu Sentai Patranger. Also he's equipped with a shark fin-like treasure called Plonge.

History
Ryugu Tamatebacco made his first appearance accompanied with a couple of Porderman where he'd a young student into an old woman when he spotted Kairi and Umika's dad he and the Pordermen chased after the two. However the police stopped him in his tracks so he'd battle them instead. He'd accidentally aged one of the Porderman into its senior years, but when Noel was about to open fire on Ryugu he used the treasure's ability to dive in the ground to avoid the attack, but attack Noel at the same time after that he retreats.

A while later he was at his home base until it was invaded by the thieves, so he battled the intruders. However when Lupin Red acquired the Magic dial he was no match for it.
