A Dark Cloud in the Sky Zone!.As SlushAngemon prepares to pass his president title to Lucemon, Shoutmon finds Lucemon in the library studying and becomes dejected while noticing Shakkoumon in the shadows. When Lucemon arrives for his coronation, Shakkoumon appears. Shakkoumon is revealed to be the electoral administrator who has been watching Lucemon to see if he was worthy of the presidency. Once obtaining the Sky Zone's Presidential Armlet and revealing the corruptive Phantom Mist to Mikey Kudo, Angie Hinomoto, and Jeremy Tsurgi, Lucemon uses an incantation to split the Sky Zone to unleash a shrine containing the Phantom Mist in order to gain its Code Crown. Lucemon Digivolves into his true form named Lucemon Chaos Mode. Lucemon Chaos Mode reveals that he is actually working for Laylamon. When Shoutmon tries to attack Lucemon for tricking him and the others, he ends up zapped upon the arrival of Nene Amano and the mysterious Digimon named Axeknightmon. Axeknightmon was promised the Phantom Mist as part of the partnership with Lucemon. Telling Mikey not to interfere, Nene releases Sparrowmon as they and Axeknightmon head to the shrine where the latter has the girl absorb the Phantom Mist into her Fusion Loader while traces of it proceed to corrupt the Sky Zone's inhabitants. Before Lucemon Chaos Mode takes off since he expected the Fusion Fighters to be unable to fight back with Shoutmon wounded, he finds himself being attacked by Ballistamon and Dorulumon before knocking them, Starmon, and the Pickmonz away. When Lucemon Chaos Mode starts to unleash an attack on Mikey, it ends up blocked by Shoutmon who now sees himself as a better Digimon King for having a heart compared to Lucemon. With Beelzemon covering them, Mikey forms Shoutmon ×4B who defeats Lucemon Chaos Mode with Shakkoumon's support. With the Fusion Fighters obtaining the Sky Zone's Code Crown, they are teleported by Shakkoumon to the shrine where they find Nene harvesting the Phantom Mist's energy before she is grabbed by Lucemon Chaos Mode. Though Lucemon Chaos Mode intends to absorb the Phantom Mist to become powerful enough to destroy the Fusion Fighters, he ends up being overwhelmed by the dark energy as it consumes him. The Fusion Fighters and Sparrowmon see the dark energy also engulfing Nene as well.
