Guygalos is the capital, and largest city, of the Guylos Empire. According to Gunther Prozen, it is located on the continent of Europa.
Guygalos is very badly damaged when Prozen revived the Death Saurer. The ancient Zoid runs rampant through the city until Prozen was foiled by Van Flyheight and his Blade Liger. It later recovers and becomes re-built under Emperor Rudolph Zeppelin III. The city features large monuments that reflect real-worlds structures such as the Hagia Sophia.
