Maildramon is a Cyborg Digimon. It armor-digivolved through the power of the "Digi-Egg of Miracles". This dragon, possessing armor made of Chrome Digizoid, is the attendant of Knightmon, and rushes about the battlefield carrying Knightmon on its back. As you would expect with the largely-built Knightmon riding it, Maildramon is also an exceptional size, so both its power and stamina are something worth mentioning. It is definitely a "Moving Fortress".

A Maildramon chases Calumon through the Network before being sidelined by a DarkTyrannomon, mimicking a similar battle playing out in the Real World as a card game between Kazu Shioda and Takato Matsuki. Although Maildramon initially overpowers the dinosaur, Calumon's power causes it to digivolve to MetalTyrannomon, who obliterates Maildramon in an explosion that catapults Calumon to the Human World.
