Yogoshimacritein

"I'm Sorry!"

- Yogoshimacriten's last words

Crime Minister Yogoshimacriten is member of the Gaiark, a race of machine humans who pollute the Braneworlds to create an ideal environment they can thrive in. He only appears in the series finale of Go-Onger, taking command of the Human World invasion force. He is the most cruel of the Gaiark and is the father of Yogostein. He is the true main antagonist of Engine Sentai Go-Onger.

History
Using Cleaning Minister Kireizky's Infinite Wastebin to enter the Human World, Yogoshimacriten assumes command over the Gaiark stationed there. Using his signature attack Justice Dissolution, Yogoshimacriten takes out Hant Jou, Gunpei Ishihara, and the Go-On Wings, along with their Engine partners, Carrigator, Jum-bowhale, and the ancient Engines. After losing the Infinite Wastebin to Kegalesia and Kitaneidas to keep him from using Justice Dissolution, killing them in the process, Yogoshimacriten makes his way to the Deus Haguruma Magear to power himself up until the primary Go-Ongers trap him in the Bikkurium chamber and destory the Deus Haguruma Magear to get their friends back, causing the Gaial's Hellgaille Palace to collapse. However, Yogoshimacritein survives and attempts to destroy the city until he is halted by Hanto, Gunpei, and the Go-on Wings.

Once the primary Go-ongers join the fray, Yogoshimacritein enlarges himself in a process called Third Industrial Revolution, fighting Engine-O G12 before being destroyed by his opponent's G12 Final Grand Prix attack.

Years later, Yogoshimacritein is revived as a member of the Black Cross Army and fights against Gokai Yellow, Gokai Blue, Gosei Black and Gosei Yellow before being defeated by their combined powers. Later, resurrected by Black Cross King with Chirakasonne and Kireizky, Yogoshimacritein is destroyed by Engine-O, Dairen'Oh, and RV Robo.

Yogoshimacritein is later revived once again, this time as a member of Dai-Zangyack. When Dai-Shocker and Dai-Zangyack reveal their alliance and fight against the combined Super Sentai and Kamen Riders, he, alongside Bat Fangire, leads an army of Gaiark and Fangire against them. He is destroyed by a combined finisher attack from the Go-ongers and Kiva.
