The Ohranger Robo is the core combining robo of Chōriki Sentai Ohranger (1995) – the very same design appeared in Power Rangers Zeo as the Zeo Megazord. On the command "Chouriki Gattai" (Super-Powered Combination), the five Chouriki Mobiles unite. These machines were built by the scientist Miura to help the Ohrangers fight the Machine Empire Baranoia.

The five components are Sky Phoenix (OhRed, a phoenix that forms the head and back), Gran Taurus (OhGreen, a sacred bull), Dash Leon (OhBlue, a lion forming the chest and arms), Dogu Lander (OhYellow, based on the Dogū clay figures of Japan's Jōmon period, forming the left leg) and Moa Loader (OhPink, inspired by the Moai statues of Easter Island). The robo's signature trait is its five interchangeable battle helmets – Wing Head, Horn Head, Graviton Head, Vulcan Head and Cannon Head – each granting different powers to suit the battle. Wearing the Wing Head, it summons the Super Crown Sword and finishes foes with the "Crown Final Crash."

The Ohranger Robo is also expandable: docking with Red Puncher creates the Buster Ohranger Robo (whose head becomes a sixth helmet, the "Buster Head," with the "Big Cannon Burst" finisher), and for the grandest entrance the robo can ride inside the gigantic carrier mecha King Pyramider.

The DX Chouriki Gattai Ohranger Robo by Bandai Japan (1995) captures all of that play value beautifully: a chrome sword, show-accurate stickers, tow chains on Moa Loader and Dogu Lander that peg onto Dash Leon and Gran Taurus, all five swappable helmets with storage slots on the back for the spares, plus working wheels and spring-out side cannons on Moa Loader and Dogu Lander via a rear button. The US release came from Bandai America as the "Deluxe Zeo Megazord": for safety and cost reasons the vacuum-metalized chrome parts (claws, knees and both halves of the Megazord Saber) were swapped for dull-finish equivalents, and the gold chains were replaced with gold-colored fiber cords. The classic is built mostly from sturdy ABS with chrome accents – heavy die-cast was reserved for later premium reissues. A wonderfully playful set whose self-contained helmet-swapping gimmick still delights collectors today.
