Susanoomon

Susanoomon is a Wizard Digimon whose name and design are derived from the mythological Susanoo. It is sometimes referred to as "Susanomon" in American Bandai materials. Told of in Oriental legends, it is the strongest destructive god and the god which governs over regeneration. It is told that when the Network System descends into chaos, it will erase the existing system, and create a new one. It wields the "ZERO-ARMS: Orochi", which emanates a gigantic sword of light. As the ultimate fusion of the twenty Spirits, it possesses each of the ten elemental attributes.

Digimon Frontier
When Koichi Kimura sacrifices himself to save the others from Lucemon Chaos Mode, he gives his Spirits of Darkness to his brother Koji Minamoto. Takuya Kanbara and Koji then bring all twenty Spirits together and become Susanoomon. In this form, they fight against Lucemon Chaos Mode, whose Ultimate Sacrifice they defeat by splitting back into humans and Spirits before the attack can hurt them. Susanoomon proceeds to cleave him with Celestial Blade and scan the light side of his Fractal Code.

Unfortunately, the dark side of his Fractal Code manifests as the enormous Lucemon Shadowlord Mode, who proceeds to try to enter the human world. Defeated in their lesser forms, the DigiDestined lose hope until the Spirits themselves, along with the Celestial Digimon, manifest in order to give them strength. Combined, all five of them, Takuya and Koji, along with J.P. Shibayama, Zoe Orimoto, and Tommy Himi, combine to form Susanoomon once more. They are able to penetrate Lucemon's "Gehenna", a dark sphere where Lucemon Larva hides. In the final battle, Susanoomon manages to shatter the Gehenna and destroy Lucemon Shadowlord Mode body. Blindsided by Lucemon Larva, however, the Spirits eject the DigiDestined from Susanoomon. They take the sword from the ZERO-ARMS: Orochi and, splitting into the Human forms of the ten Legendary Warriors, they destroy Lucemon for good.
