Lord Megadeath

Lord Megadeath is a robotic-like digital life form born from inside the network that is the true mastermind and leader of A.o.A. He plans to replace humans to become the ruler of both worlds. To do this he has his organization steal the matrix data of humans and turn them into Oinkmon so that the matrix data can empower Vemmon causing it to digivolve into Snatchmon and further use it to create the perfect digimon partner. While preparing the matrix data to four Vemmon he had one Vemmon take control of the Juggernaut battleship which further digivolved into Destromon and attacked a city.

After the supposed defeat of A.o.A. he challenged the hero Junior to a battle to prove he is the strongest tamer at the true target of A.o.A., the Gunslinger Space Station. While there he fought Junior with his partners, Fujinmon, Suijinmon, and Raijinmon and lost. But Lord Megadeath claims it was only a test as he still had Snatchmon. He teleports away but Junior follows where he witnesses the four Vemmon digivolve into Snatchmon. Lord Megadeath order Snatchmon to attack but Snatchmon refused claiming he did not need a tamer and absorbed Lord Megadeath. Effectively destroying A.o.A. for good.
