Kaijuzilla is a Daikaiju used by Kajiuzilla2000. Kaijuzilla has an obscure past, but he is no doubt an Earth Defender.
Kaijuzilla was found on Monster Island in 1990. Ever since, he roamed peacefully until 2004, when he escaped the Monster Island round up by the Xiliens. Recently Kaijuzilla has developed an enemy in the form of Zardoris.
