Digimon Story: Super Xros Wars Blue & Red
Barbamon uses System Omega to revive Armamon. It loads the Digicores collected from ROG's leaders, explaining that their dark hearts are required for the revival. The installation announces the progress of its Compound System Digicore Load and regenerates Armamon when the final data injection reaches its limit. While the process continues, Barbamon creates two additional versions of itself to fight Xros Heart, allowing it to remain at the controls.
After awakening, Armamon rejects Barbamon as its wielder and forcibly transforms it into a weapon. Armamon reveals its intention to gather the Zone's Digimon into System Omega and become a single weapon, believing that this will allow it to protect the LS-tou Zone from all invaders.
Following its initial defeat, Armamon accesses the mainframe to search for Dynasmon. The system reports that Dynasmon's Digimon ID is lost and identifies Stealth Valley as its last confirmed location. Armamon begins gathering surrounding data in an attempt to reconstruct its former partner, despite Spadamon's insistence that such a reconstruction would not be the same Dynasmon.
Armamon DigiXroses with Barbamon and System Omega to become Omega Armamon Burst Mode. Fully connected to the system, it threatens to absorb Lost Space and the entire LS-tou Zone in its search for data. Spadamon reasons that its own status as a Weapon Digimon may allow it to access System Omega. It initiates a security protocol, after which the system announces a gate code rejection and activates full protection of Omega Area, sealing the area to prevent Armamon from escaping.
After Xros Heart defeats Omega Armamon Burst Mode, System Omega detects an abnormality in its Digicore but fails to terminate the incoming data. The reported damage continues increasing until the Digicore collapses. The system issues a Code Red warning and orders the immediate evacuation of Lost Space as a black hole threatens the area.
The Warp Gate is broken, while Omega Area's sealed state prevents the use of Gate Disks. Spadamon uses a remaining system function to send Taiki and Shoutmon back to Sky Fort, staying behind to stop Armamon. Spadamon subsequently returns and explains that it eliminated Armamon together with the black hole. Lost Space itself remains in existence, with its dangerous areas sealed.
