Gigant Bragi-Oh (Japanese: ギガントブラギオー) is the giant-robot mode of the Zyudenryu Bragigas (Beast Battery No. 10), the largest of the Guardian Beast "Zyudenryu" in the 2013–2014 series Zyuden Sentai Kyoryuger. Bragigas is the partner of Wise God Torin, later Kyoryu Silver, and is treated as the king and god of the Guardians. In the show's backstory the Zyudenryu that fell in battle 100 million years earlier were turned to amber by Bragigas' tears, becoming the thirteen "Guardians' Secret Stones"; Bragigas itself was sealed at the bottom of Lake Mado after firing its forbidden Gigant Cannon, and was revived only once all thirteen stones had been gathered by Dantetsu Kiryu and the Kyoryugers. In the American adaptation Power Rangers Dino Super Charge (2016) Bragigas corresponds to the Titano Zord, whose battle form is the Titano Charge Megazord, so the mecha is not Japan-exclusive, though the US release is a separate, differing version.

Bragigas performs a "Cho Kamitsuki Henkei" (super biting transformation), rising into the Zyuden Giant Gigant Bragi-Oh with the Gigant Cannon carried as its signature back-mounted weapon. Its core function is combination with the five main Zyudenryu — Gabutyra, Stegotchi, Dricera, Zakutor and Parasagun, i.e. the complete Kyoryujin — which together with Bragigas form the oversized Gigant Kyoryujin, uniting the core team with their mentor. The long brachiosaurus neck doubles as the primary biting element and weapon.

The DX toy was released by Bandai (Japan) in October 2013 as "Cho Kamitsuki Henkei DX Gigant Bragioh," the large year-end flagship of the Kyoryuger line (retail roughly 9,000–12,000 yen). It is made predominantly of plastic (ABS/PVC), as is standard for the Kamitsuki Gattai range, and as Gigant Bragi-Oh it stands over half a metre (about 52 cm per the manufacturer's figure), making it one of the largest DX Sentai mecha. The change from beast to robot mode is a single-piece transformation with built-in electronic sound and light gimmicks, and a rack on its back holds all thirteen Zyudenchi (Beast Batteries), echoing the thirteen-Guardian storyline. It includes Zyudenchi No. 10 (Bragigas). To build the complete Gigant Kyoryujin it combines with the separately sold DX Kyoryujin plus Zakutor and Parasagun.
