- ―Final words upon his death[src]
A dynamite Savage Land Barbaric Machine Beast sent by Yogostein to destroy the city and almost defeated the Go-Onger until the Go-on Silver and Go-On Gold interfere. Hiramechimedes and Yogostein plotted together to target the five Go-Onger in order to call out the Go-On Wings. Unfortunately, they were all bested by Go-On Wings. He is defeated by Go-On Gold and he tries to grow giant but is unable to do so because Gold took his Bikkurium. He simply exploded and hence was destroyed.
