Kaizoku Gattai Twokaioh ("Pirate Combination Twokaioh") is the personal mecha of Twokaizer, the sixth warrior of Kikai Sentai Zenkaiger (2021), the 45th Super Sentai series. Twokaizer, real name Zox (Zocks) Goldtsuiker, is a golden space pirate who does not belong to the core Zenkaiger team but operates independently with his crew, the Goldtsuikers. The foundation of his mecha is the golden, crocodile-themed battleship CrocoDaiOh, joined by two sentient Kikainoid partners, Twokai Ricky and Twokai Cutanner, each of which embodies the "power" of an earlier Super Sentai series - Ricky that of Chouriki Sentai Ohranger, Cutanner that of Samurai Sentai Shinkenger. Because Zenkaiger was never adapted into Power Rangers, this mecha exists solely in its Japanese form; no official Power Rangers version was ever made.

Through the Pirate Combination (Kaizoku Gattai), the three components dock together. CrocoDaiOh itself can split into the ship CrossKaiOh and the motorcycle Crawlingoh, and can be rebuilt into the Crocodai Bazooka. Depending on which partner forms the head, two main configurations result: in Twokaioh Cutanner, Twokai Cutanner becomes the head, CrocoDaiOh the body, and Twokai Ricky the katana-wielding left arm. In Twokaioh Ricky, Twokai Ricky becomes the head, CrocoDaiOh the body, and Twokai Cutanner the right arm ending in a gatling-style cannon (Super Ricky Gun). In total the three units can be arranged into up to six different modes shown in the series; Cutanner favors a saber/katana in combat, while Ricky uses his gatling weapon.

The DX toy was released in June 2021 by Bandai (Japan) as the set "DX Kaizoku Gattai Twokaioh," which includes all three components: CrocoDaiOh, made predominantly of ABS/PVC plastic (splitting into CrossKaiOh and Crawlingoh and converting into the Crocodai Bazooka), plus the two robot figures Twokai Ricky (with gatling weapon) and Twokai Cutanner (with saber). The set builds both main forms - Twokaioh Cutanner and Twokaioh Ricky - as well as the additional combination modes; Bandai sold it as a single DX set with no US counterpart. Alongside the DX release, Bandai also offered a smaller Mini-Pla model-kit version (candy toy). As the series received no Power Rangers adaptation, Twokaioh was never produced as a Power Rangers toy and is therefore Japan-exclusive.
