Megidramon

Megidramon
Megidramon is an Evil Dragon Digimon, one of the Four Great Dragons. His name comes from the word "Megiddo", the place where Christians believe the final battle between good and evil will take place. He is body wrapped in a body made of Chrome Digizoid. He is a rare (in fact, unique in every game) species whose reason for existing is unknown, but is said to be one of the very incarnations of the Digital Hazard, a power of malice that is sealed away by an unknown "force". However, when that power is awakened, he creates a system meltdown which could destroy the Digital World.
