Trinoid #12: Yatsudenwani (トリノイド12号 ヤツデンワニ, Torinoido Juuni-go: Yatsudenwani) (18, 21-Dekaranger vs. Abaranger): Nihon no Yatsude (Japanese Fatsia) + Denwa (Telephone) + Wani (Crocodile).


A powerful Trinoid who was seemingly killed by AbareKiller before he could do any harm. But in reality, he was captured and forced to be Mikoto's manservant, making Yatsudenwani a disgrace to his "dad", Mikela. To redeem himself, he decided to capture the other Abarangers, resulting with his crush on Ranru Itsuki and stalking her on occasion via phone. But soon, after the Killer Giganoid incident, Yatsudenwani moved into Dino House and became a member of its staff. In #44, Yatsudenwani used a new power, "TeleCroco Dream", to put the Abarangers into a deep slumber until they woke up and retaliated with Super Dino Bomber. However, the entire episode was just a bad dream the Trinoid had. In the end, Yatsudenwani chose to stay on Earth as he had nowhere else to go.

In Dekaranger vs. Abaranger, it was revealed that he now runs the flourishing Dino House and its branches as CEO. Furthermore, Yatsudenwani held an artifact capable of resurrecting Wicked Life God Dezumozorlya. In addition, he glomped Banban Akaza (DekaRed) while mistaking him for Ranru, and eavesdropped on Ranru, Emiri Imanaka, Umeko, and Jasmine while they were bathing, resulting in a severe beating during the group's victory meal.

He was among villains captured within the Space Prison in Makuu Space in Kaizoku Sentai Gokaiger vs. Uchuu Keiji Gavan: The Movie and released by the pirate Sentai as they caused a big ruckus within. As it was in Abaranger, his perverted nature lead him to harrass Luka and Ahim.
