He is Mega Digimon.
Machinedramon resembles a mechanical Dragon. He also has dual cannons on his back.
Although he speaks quietly, Machinedramon is as ruthless and insane as Piedmon or Puppetmon. He is also the second biggest Dark Master among the group, MetalSeadramon being the biggest. He is a monstrous sadist who loves to destroy, and of all the Dark Masters employed the most brutal, offensive approach by dispatching the forces of the metal empire to eliminate the Digidestined. He is probably the most intelligent of the Dark Masters, as demonstrated by his tactic of using Izzy's computer. However he is not above mindless destruction, and will murder anyone with no remorse whatsoever. His destruction of all the Numemon makes him the most prolific murderer of the Dark Masters.
