A.o.A is a European cybernetic terrorist group and one of the antagonists of Digimon World 3. Junior hears them on the TV at Kusanagi City in the real world.
A.o.A's Past
The A.o.A is known to have been the cause to numerous cybernetic terrorism attacks across the world, with most of its top agents recently arrested by the International Police known as S.A.P.
A.o.A's Plan
The MAGAMI Corporation which hosts Digimon Online, is actually a cover for the A.o.A. Most of its staff is part of the terrorist group, though some people are unaware of what they have gotten themselves into. Through Digimon Online, the A.o.A planned to create an artificial digimon which could combine its matrix data with anything, creating a fearsomely powerful and loyal digimon that would help them conquer the world.
Kurt's Interference
Kurt, aka, Lucky Mouse, who is Kail's brother found out about the A.o.A's plans and stole the Digitama of Vemmon, the digimon the A.o.A would use to conquer the world. He also set up a protective barrier between the Asuka and Amaterasu Servers, so Bulbmon, which the the transportation digimon of the A.o.A, would be unable to dig a Network Hole through to the Asuka Server. As a result of his action, Bulbmon broke down and it threw out its load of A.o.A troops near Byakko City in the West Sector, who raided it and took it under their control. The Matrix System also broke down during this incident for some reason, rendering everyone connected to Digimon Online unable to log off and return to the Real World.
A.o.A's First Attack
The A.o.A's first attack occured when Vemmon was hatched from his Digitama and merged with the experimental Juggernaut battle ship in the Real World, creating Destromon, who immediately started attacking the Naval Fleet and Fighter Squadrons that had been dispatched to intercept the ship after it was launched to the surface from the Undersea Base Magasta, following Junior's failure to stop it in time. Destromon is later stopped using the control panel in Amaterasu's A.o.A headquarters, resulting in the self destruction of the monstrous digimon before it is able to fire its gigantic particle cannon at the city it had landed on.
Beginning at Digimon Online
The A.o.A plan to attack Digimon Online. Later than Lucky Mouse appears, but the A.o.A know that Lucky Mouse is going to prevent the attack, and they make Lucky Mouse (Kurt) an Oinkmon
A.o.A First Attack
The A.o.A First attack was to Byakko City, at Asuka´s West Sector, they took over the city, and attacked all the villagers. Also, there was a A.o.A´s Soldier (maybe the captain), being the leader (he is fake), when you defeat him, he will send you to the Prisioner´s Cell, later, you see Numemon, and he will help you to get out of there, when you defeat the REAL Leader, the troops leaves, an plan their second attack to Asuka City.
A.o.A, Second Attack
After Junior defeats Byakko's City Leader, A.o.A attacks Asuka City and takes over the Admin Center with Tankmons and Guardromons. Junior know, however, that the Game Master is an A.o.A soldier and takes her out. With her defeat, the city reverts to normal, but they know that they are going to attack other places.
A.o.A and the Amaterasu Server
By the Catacombs in South Sector, the A.o.A bring Bulbmon to make a "dimensional tunnel" to the Amaterasu Server. The tunnel leads to the Forest Inn, but first Junior defeats a more powerful Bulbmon.
