Maildramon

Maildramon is the Armor Digivolved form of Gatomon through the Digi-Egg of Miracles. She towers over most opponents and may crush them with her large bulk and thick tail, although she prefers to attack with lightning and thunder. She is covered in a legendary golden armor that protects her from attacks. Her name comes from chain mail and dragon.

Digimon Tamers
A Maildramon was chasing Calumon before being tackled by a DarkTyrannomon, but Maildramon overpowered it. During the battle, a blast sent Calumon into the Real World as he witnessed DarkTyrannomon emerge as MetalTyrannomon and destroy Maildramon by crushing him with his hand. This appeared to be a reflection of a card game played by Takato Matsuki (who had Dark Tyrannomon) and Kazu Shioda (who had Maildramon).

Digimon World 3
Maildramon can be found in Asuka's West Sector, in Mobious Desert. Its black color variant can be found in Amaterasu's North Sector, in Kulon Pit and Kulon Mines. In the PAL version of the game, the black Maildramon can be found in Amaterasu's Circuit Boards underground, once Galacticmon has been beat.

Attacks
 * Iron Press: Belly flops onto her foe crushing them with her huge bulk.
 * Lightning Spear: Charges her horn with electrical energy which she turns into a bolt of lightning which is shot at her foes, zapping them.
