MegaSeadramon is a Sea Animal Digimon whose name and design are derived from "Mega Seadramon". It was a Seadramon-species that lived long in the harsh environment surrounding Folder Continent, but digivolved in order to survive in the Digital World where the weak are food for the strong. Its body became a size larger, the carapace covering its head got harder, and a lightning-shaped blade has grown on its calvaria. Its intelligence has developed more than the Seadramon-species, so it chases its opponent persistently, like a seeking torpedo, and reliably brings them down. There is a generator device equipped in the carapace on its head, in order to enable its Special Moves.[4]
