Yokubarido is the leader of Zangyack's "Special Destruction Unit".
A gambler assigned to utilize Gigarollum, a rare material capable of destroying planets with a single shot, on planets that prove troublesome. His special weapon is a deck of exploding cards. His ship was part of a Zangyack fleet which arrived on Earth and attacked, intended to use the Gigarollum there, the fleet was beaten back by Magi GokaiOh but by Joe's insistance, Yokubarido's ship was spared.
Joe explained to the crew that the green ship is the flagship of Zangyack's "Special Destruction Unit", as it uses a cannon that uses ammo made of Gigarollum and destroying the ship would have caused the Gigarollum aboard to explode and scorch the Earth's surface. Luka then suggested that she and Joe infiltrate the ship and steal the Gigalorium. As the ship was docked over an abandoned mining field, GokaiBlue and GokaiYellow used their color respective Boukenger Keys to sneak under and board it. Inside, Joe and Luka disguised themselves as Gormin and made their way to the ship's armory where the Gigalorium was. However, they were taken to a break room by two Sugormin to play a game of poker. Luka offered to play against both Zugormin, using her sleeve trick to cheat her way. The games that follow attracted every Gormin on the ship before the game was suddenly stopped by Yokubarido when he exposed Luka's cheating and then her and Joe's disguises.
However, as a gambler with respect in their guts stowing away on his ship, Yokubarido offered to let them go if they could beat him in a game. If they lost, they must surrender for him to collect their bounty. With the Action Commander using own deck, Joe offered to accept his challenge in place of Luka despite the disadvantages piled against him. Yokubarido shown a four of a kind, but Joe miraculously beaten him with a royal flush. Refusing to accept that he lost, Yokubarido ordered his troops to kill Joe and Luka when the rest of the crew arrived in Gormin guises. It was revealed that the card game was a planned diversion to have the trio sneak into the armory and steal the Gigarollum. GokaiGreen then sets off an explosive to sink Yokubarido's ship as he and surviving troops were forced to watch the Gigarollum capsule being taken by Navi to the Gokai Galleon. After disposing of the Gormin, the Gokaigers used the J.A.K.Q. Dengekitai Keys to take out the Zugormin officers with the Big Bomber attack before using Final Wave attacks on Yokubarido. After being enlarged by Insarn, Yokubarido used his explosive card attack on Gokaioh before the robot presented Gigalorium. Intending to return it, the Gokaigers had Gokaioh throw it into space towards the Zangyack fleet, taking out more of the ships in the process, before forming Gao Gokaioh to finish Yokubarido.
He later appeared as one of the many monsters in the Dai-Zangyack army, which eventually fought against an army of Super Sentai and Kamen Riders. He is seen fighting DynaRed in the background of the first aerial scene, then fighting Blue Flash in the second scene.
