Guygalos during Prozen's regency at night.
Guygalos is the capital, and largest city, of the Guylos Empire. According to Gunther Prozen it is located on the continent of Europa.
Guygalos was 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 recovered and was re-built under Emperor Rudolph Zeppelin III. The city has large monuments built that reflect real-life structures such as Hagia Sophia, built in Constantinople (now Istanbul).
