Lucemon appeared in Digimon Frontier, believing that other Digimon were incapable of thinking for themselves, and that the world would be a better place if he had absolute power and made all the decisions. After falling from grace and heaven to to corruption by his own power, Lucemon evolved into Chaos mode, which was sealed by the Ancient Warriors, including AncientGreymon.

Susanoomon was reformed once again, and was able to drag Lucemon Shadowlord Mode back into the Digital World. After destroying the Gehenna, the dragon went on a rampage due to Lucemon Larvae no longer able to control it. Susannomon still managed to destroy the berserk demon with the 'Orochi Slayer'.

Lucemon begins absorbing darkness and kidnaps Nene. However, due to absorbing TOO much darkness, Lucemon Chaos Mode involuntarily transformed into this form, proceeding to feed off of Nene's darkness as well as the data of the citizens and the very data of the Heaven Zone. Shoutmon X4 manages to break open the dark sphere in his claws, allowing Sparrowmon to fly in and swiftly rescue Nene. Nene agrees to help Taiki and Digixroses Sparrowmon with Shoutmon X4 to make Shoutmon X5, who obliterates the shadowy and malovent demon god.
