|~ Great Door World's final words before his death.|
Great Door World is one of the two main antagonists (the other being Door World) in episode 8 of Kikai Sentai Zenkaiger, appearing as. Great Door World is a door-themed World of Tojitendo, created from the Door Tojiru Gear that contains Doortopia.
He was voiced by Shōya Chiba, who also voiced Door World.
The Great Door World made his first appearance after the destruction of his counterpart, due to the need of an even fight between Stacey and Kaito. Upon the creation of it, Great Door World has summoned a bunch of giant doors all over the hillside, prompting the giant robots to form ZenkaiOh JuraGaon and VrooMagine as they battle the Great Door World while Kaito holds off Stacey as he summons the Flashman via Dark Sentai Gear number 10.
The battle goes off as the Great Door World used his Key Arm Blaster on one of the giant doors, as he summons spears to attack JuraGaon from behind, a pair of boxing gloves (which resembles the Bun Knuckles that were worn by the Boxing World from Episode 4) and a couple of giant Kudakks.
He then used this ability as he open fire at the two mechas, but JuraGaon used the shield to block that attack while VrooMagine takes to the sky and destroyed a couple of giant doors. After that, he was then destroyed once and for all by the combined finishers of both Juran Sword Full Moon Crush and Vroon Picker Accel Strike, thus freeing the Doortopia from the Tojiru Gear.
