Susanoomon is the legendary hero in Digimon Frontier and alter-ego of Takuya and Koji combined.
Susanoomon first appeared after Lucemon defeated Loweemon and purified Kouchi's data, which enraged Takuya. Lucemon still managed to defeat Susanoomon, but Susanoomon, however, survived his Ultimate Sacrifice attack and defeated Lucemon with his Celestial Blade attack. However, Lucemon returned into his ultimate form, Lucemon Shadowlord Mode. Susanoomon pinned him down with his Heaven's Thunder attack and finished Lucemon off with his Celestial Blade attack.
