The Dried Cracked Ground! I am Land Pollution Minister Yogostein!
~ Yogostein's catchphrase when he enters into battle.

Land Pollution Minister Yogostein, whose true name is Baron Yogorex de Stein, is one of the three Pollution Ministers of the Banki Clan Gaiark and the secondary antagonist of Engine Sentai Go-Onger. He served as the main antagonist for its first half.

He was voiced by Kiyoyuki Yanada, who later voiced Yogoshimacritein.


Engine Sentai Go-Onger

Yogostein arrived on Earth with his fellow pollution ministers Kitaneidas and Kegalesia and used the Deus Heguru Megear to establish Hellgaille's Palace on an isolated island in the middle of the ocean.

Yogostein was happy to see his subordinate Hiramechimedes arrive to assist the Pollution Ministers in destroying the Go-Ongers. After Hiramechimedes was killed in a battle with the Go-Ongers, Yogostein took significant time to mourn his fallen comrade.

Yogostein later enacts a project to unearth the Horonderthal and uses it upgrade himself into the new Horonderthal King. With his new powers, Yogostein attempts to rust the entire city, but his upgrade is canceled by Engine-Oh G12. Yogostein then fights Go-On Red in a one-on-one duel and is ultimately killed by the Red Go-onger.

Shinkenger vs. Go-Onger

Yogostein was later revived along with Kitaneidas and Kegalesia. Pollution President Batcheed attempted to recruit the three back into the Banki Clan Gaiark as they were eating sushi from Genta's cart, but the three did not want to fight anymore and instead wanted to retire at the bottom of the Sanzu River and get drunk.

Gokaiger vs. Gavan

Yogostein was among villains imprisoned within the Space Prison in Makuu Space by Makuu Prison Warden Ashurada. Yogostein and the other villains were later released by the Gokaigers when they caused a big ruckus within the prison.


  • His name is from the Japanese word for "to soil" (汚す yogosu).
