English Title: Digimon Adventure 02
Genre: Action, Adventure
Episodes: 50

Summary: It is the direct sequel to the previous series and takes place three years after the original series. With most of the original characters now in junior high school, the Digital World was supposedly secure and peaceful. However, a new evil has appeared in the form of the Digimon Emperor (Digimon Kaiser). This new villain is different - he's a human just like the DigiDestined. The Digimon Emperor has been enslaving all Digimon in sight with Black Rings and Control Spires and, to make things worse, has somehow made regular Digivolution impossible. Three new children are chosen to save the Digital World and, along with T.K. and Kari, make up the new generation of DigiDestined.

Episodes 1-21: Taking place a few years after Digimon Adventure, the Digital World comes under attack by a mysterious human calling himself the Digimon Emperor who is enslaving Digimon with his black rings while building Control Spires that negate Digivolution. To fight him, T.K and Kari, along with three new children, gain a type of Digivice called a D3, which allows them to open a gate to be transported to the Digital World through any computer and a D-Terminal that holds Crest-themed relics called Digi-Eggs (DigiMentals) that allow Patamon and Gatomon, along with the new Digimon Veemon, Hawkmon, and Armadillomon to Armor Digivolve as a counter to the presence of Control Spires. They eventually stop the Digimon Emperor, revealed to be the boy genius Ken Ichijouji, thanks to the sacrifice of Wormmon, Ken's partner.

Episodes 22-37: With the Digimon Emperor defeated, the DigiDestined proceed to help the resident Digimon rebuild their homes. However, after his defeat, and soul searching, Ken learns of a mysterious woman who can turn Control Spires into constructs resembling living Digimon. Though Veemon, Hawkmon, and Armadillomon were able to Digivolve naturally, the Control Spire Digimon prove to be stronger until Ken joins the gang and they learn of DNA Digivolution, enabling their Digimon to fuse with each other in pairs for more power. However, the mysterious woman, revealed to be a human-Digimon hybrid called Arukenimon, responds by creating BlackWarGreymon. Though the construct refuses to follow her orders, Arukenimon and her lackey Mummymon take advantage of his drive to destroy the Destiny Stones that keep the dimensional barriers of the human and Digital Worlds from blending.

Episodes 38-50: Eventually, when the battle was brought to the Real World, Arukenimon and Mummymon's boss, Yukio Oikawa, makes himself known. Despite interference from Daemon and his forces, Oikawa extracts from Ken data of the Dark Spore, the object responsible for Ken becoming the Digimon Emperor, and copies it into a group of 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 DigiDestined confront Oikawa, only to learn he is a loner whose only friend in the world was the late Hiroki Hida, Cody's father, and that his actions were so he can enter the DigiWorld.
However, it was then revealed as Oikawa attempted to make his way into the Digital World that he was only a pawn/vessel for the true mastermind, Myotismon from the first series, now reborn as MaloMyotismon. Eventually, after a long battle with aid from the DigiDestined from all over the world, the Japanese DigiDestined destroyed MaloMyotismon. Though weakened from the evil Digimon's possession, a dying Oikawa sacrifices his physical existence to return the Digital World to its peaceful state and serve as it guardian. In the series aftermath, twenty-five years later, the humans and Digimon live side by side as the Japanese DigiDestined gather together with their families.
