GigaSeadramon is an Android Digimon and a carrier of the X Antibody whose name is derived from "Giga Seadramon". As a successful elaboration on MetalSeadramon, it demonstrates the fastest speed of movement and strongest ability for interception under the sea. In order to further expand its sphere of influence, the Crack Team constructed this massive Digimon in absolute secrecy and endowed it with the ability to control the sea and possession of a cruising range which covers the vast Net Ocean. Its overall length exceeds even that of Whamon, and since Digimon belonging to the Crack Team, such as Chaosdromon, can be loaded in its interior, it is no longer a lone Digimon, and it seems possible to say that it is an assault landing ship for which it isn't known when and where it will appear on the Net Ocean, or when it will launch an attack.[4]
