Mugendramon

Machinedramon is the third of the Dark Masters of Digimon Adventure.

He is a Mega Digimon.

Appearance
Machinedramon resembles a mechanical Dragon. He also has dual cannons on his back.

Personality
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.

Digimon Adventure
In Enter The Dark Masters, In his first appearance with the other Dark Masters, he unexpectedly attacked Angemon and then attacked the 7 Ultimate Level Digimon before they could attack him and defeated them.

In My Sister's Keeper, after Puppetmon was defeated, the Digidestined wandered into Machinedramon's territory along a road in the middle of nowhere, until Kari Kamiya developed a fever and kept passing-out, making Tai Kamiya upset since this brings memories from his child-hood past with Kari. Izzy Izumi sent Tentomon to look for help, he soon Digivolves into Kabuterimon and transports everybody to a city that has famous buildings from Earth fused into one big city. They soon find a house for Kari to rest while being watched over by T.K. Takaishi, Patamon, Gatomon, Sora and Biyomon. Tai, Agumon, Izzy and Tentomon went into the city to look for a hospital in search of medicine for Kari. Izzy used his laptop and plugged it into the network to find one, unaware of Machinedramon's Hagurumon tracking them every time Izzy used his Laptop.

Machinedramon sent his Metal Empire troops to hunt them down. Tai, Agumon, Izzy and Tentomon managed to escape the carnage from the hospital getting the medicine. The third time Izzy uses his Laptop and discovers that they are tracking him by him plugging into the network. Izzy decided to do a little trick, Hagurumon soon become confused when the network has been accessed from different points in the city, but this back fires as Machinedramon ordered plan Operation Elimin-8 (pun on the word eliminate), which consisted of having Megadramon and Gigadramon destroy every single building. But this doesn't work, so Machinedramon decided to finish them off himself. After the house everyone was staying in blows up, Tai finds the others have escaped just before bombing commenced. Machinedramon appears and everyone runs into a building, which collapses into the ground because of Machinedramon's Giga Cannon attack. The Digidestined then sink underground. Machinedramon then assumed that they were dead.

In The Crest of Light, Kari manages to recover from her fever and is well again, Sora, Biyomon, T.K, Patomon and Gatomon then soon set off to find Tai and Izzy since they landed somewhere else. However they soon find a WaruMonzaemon who is a Slave Master to the hundreds of Numemon who are used to power Machinedramon's City. Kari then gets possessed once again by the odd-spirit that spoke to the Digidestined through her body, while WaruMonzaemon gets distracted by Sora, the spirit possessing Kari frees the Numemon and they start calling her 'Queen Kari'. When Sora, T.K, Patamon and Biyomon meet up with Kari and all the Numemon, WaruMonzaemon bursts in to find the Numemon have turned against him and begin to attack, when Kari's body starts to glow in light, the energy from her allows Patamon, Gatomon and Biyomon to digivolve and give Numemon enough energy to get back up. WaruMonzaemon is then badly injured and escapes, while the spirit possessing Kari's body leads the way to Tai and Izzy. WaruMonzaemon reports to Machinedramon that the Digidestined are still alive and Machinedramon is angry that he didn't tell him sooner and as a "reward", he blasts WaruMonzaemon's arm off (Machinedramon kills him in the Japanese series). Tai and Izzy soon find Andromon who is trying to build up a resistance force to stop Machinedramon, and also fix a dripping pipe. Machinedramon appeared and Andromon managed to hold him off for Tai and Izzy to find the others. Soon everyone is back together, however Andromon is defeated, but is able to get back up to his feet. Not even the combined efforts of Andromon, Angemon, Angewomon and Birdramon can defeat Machinedramon. When he wants the first victim to be killed, Kari approaches him, but the Numemon cover his body to save 'Queen Kari'. The slug Digimon try to stop Machinedramon but were wiped out easily by the villain's "Catastrophe" attack. Kari collapses and Agumon is hit by a beam of light, causing him to Warp-Digivolve to WarGreymon. He charges up to Machinedramon, slicing him up "like an onion" with his Dramon Destroyers before regressing back to Koromon. Machinedramon starts to split and disappear. Despite being cut into pieces, Machinedramon manages to survive, though barely, and meets a dying Kimeramon, they DNA digivolve to form Millenniummon.
