The Soundbirdmon are recurring antagonists in the 2020 reboot of Digimon Adventure. They serve as henchmen of both Devimon and Negamon, brainwashing other Digimon to be under their masters' control.
Biography[]
In the ancient past, the Soundbirdmon were originally Ghoulmon, the King of the Army of Darkness that fought with the Army of Light with Millenniummon being his army's ultimate weapon. According to records, Ghoulmon's intention was to destroy both the light and the dark, something that wasn't understood given his status as a Dark Digimon. Unbeknownst to everyone at the time, Ghoulmon's true intention was to release Negamon and begin the Great Catastrophe which would suck everything into a white void. However, his army was defeated when WarGreymon and MetalGarurumon DNA digivoled into Omnimon and destroyed Millenniummon.
Thought to be destroyed in the ancient battle, Ghoulmon survived as many Soundbirdmon, evil Rookie-level Digimon that were fragments of himself. The Soundbirdmon were employed on many occasions by both Negamon and Devimon to brainwash innocent Digimon into doing their bidding, mainly to attack the DigiDestined who were often forced to destroy those that the Soundbirdmon brainwashed.
After the DigiDestined unlock the mystery of their Crests, Devimon warns Takeru and Patamon that he can sense the "sound that once drove the world mad" happening again while a massive swarm of Soundbirdmon attack the Tree of Information and even more darken the skies in preparation for Negamon's release. The DigiDestined battle the Soundbirdmon, releasing that they are what Devimon was referring to in his warning. The Soundbirdmon attacking the Tree fuse together into their true form, Ghoulmon once more, shocking the DigiDestined and Wisemon with his appearance. As Wisemon finally understands Ghoulmon's true purpose in the ancient war, he blasts the Tree, but the DigiDestined partners block the attack. The hope and light of all the Digimon believing in them causes MagnaAngemon and Angewomon to digivolve into their Mega forms of Seraphimon and Ophanimon who prove to be more than a match for Ghoulmon. Seraphimon and Ophanimon destroy Ghoulmon, causing all of the other Soundbirdmon to be destroyed as well. However, Ghoulmon's destruction releases Negamon to begin the Great Catastrophe.
