|~ Final words before death|
The Great Retro World is one of the two main antagonists in Episode 15 of Kikai Sentai Zenkaiger. He is a retro-themed Great World monster of the Kikaitopia Dynasty Tojitendo created from the retro Tojiru Gear that contains Retrotopia.
He was voiced by Yō Kitazawa, who also voiced the Retro World.
The Great Retro World made his first appearance after the destruction of his human counterpart, as he transforms the surrounding area to matches the 1970s, prompting the team to bring out ZenkaiOh JuraGaon and TwokaiOh Cutanner.
During the fight, the swordsmen mecha began attacking the Great Retro World until they hit the Natsuka Shield, which caused Great Retro World to activate this ability on the heroes before he fired a large laser beam (which resembled the Ultraseven's Wide Shot) from his Tokiwomodo Sword.
However, this is his undoing, as he has no clue what the heroes were saying due to their lingo as they kept attacking him. He was then destroyed by the Juran Sword Full Moon Crush and Cutanner Tou: Raging Fire Big Slash techniques, thus freeing the Retrotopia from the Tojiru Gear.
