A new generation of Digi-Destined, composed of three new children, as well as Kari and T.K. from the original Adventures series,
are given a new kind of digivice known as D3, which allows them to open a gate to be transported to the Digital World through
any computer. Another advantage was Armor Digivolution, using a device called a Digi-Egg/Digimental (not related to the Digi-Egg
that defines the earliest life stage of a Digimon) so their Digimon can evolve in the presence of Control Spires. They eventually
stop the Digimon Emperor, Ken Ichijouji, thanks to the sacrifice of Wormmon, Ken's partner.
After his defeat, Ken repents his evil deeds and joins the Digi-Destined as they fight an evil Digimon named Arukenimon
and her lackey Mummymon. Arukenimon has a unique power to turn the Control Spires into super-strong, artificial Digimon in
her control. To fight this new threat, the gang learns of DNA Digivolution, enabling their Digimon to fuse with each other
in pairs for more power. Eventually, when the battle was brought to the Real World, the true mastermind, Yuiko Oikawa, makes
himself known. This man extracts the Dark Spore inside Ken and implants it into other children who wish for the greatness
the old, evil Ken had. Those spores develop into flowers that harvest the infected children's energy. Eventually, the Digi-Destined
confront Oikawa, only to learn he's an extreme loner whose only friend in the world was Hiroki Hida, Cody's father. Hiroki
and Oikawa used to play old video games when they were young, eventually becoming obsessed with the Digital World and dreaming
of going there one day. In the end, an entity springs from this man's body, none other than the real mastermind, Myotismon
from the first Adventure season, now reborn as MaloMyotismon.
Unlike Adventure, which was set in the Digital World except for a temporary return to the Real World, Adventure 02 characters
shuttle back and forth between the two worlds almost every episode.
This season ended with the help of Digi-Destined from all over the world, using the light that existed inside each one
of them and their wishes to return the Digital World into a peaceful world again. Oikawa, who is too weak to enter the Digital
World, becomes its guardian as he passes away. After peace is restored, the boundary between the Digital and the Real World
is broken down, giving every human their very own Digimon companion.
