Machinedramon was the commander of Guardian Army group stationed in the Metal Zone who use the Digimon they imprisoned to stay in the prison block. He has a berserker personality prone to raging, so his subordinate LoaderLiomon tries to use Digimon they enslaved to dig up the area's Code Crown. He is a cruel, insane, angry and smart antagonist with a rudish mentality.
Machinedramon keeps eating old junkyard cars, metallic materials, and pieces of iron make his body more powerful, and is keep looking for good "foods." However, before using his Giga Cannon attack, his body becomes surrounded by blue flaming aura. Meanwhile, his right arm becomes a electromagnetic.
