Spring break turns into a summer war when the evil Diaboromon wreaks havoc on the internet, and Tai and Matt must achieve a new Digivolution to defeat him! Will Tai and the Digidestined save the world, and will Sora ever forgive Tai for giving her a hair clip?

After the older DigiDestined are abducted by the mysterious Kokomon, the next generation of kids team up with American DigiDestined Willis to rescue them - only to discover that their enigmatic enemy has an unexpected connection to their new friend!

The DigiDestined go up against Diaboromon again. Tai and Matt head back to the Internet to deal with him with Omnimon, while the younger Chosen Children go to deal with the rampage of a swarm of Kuramon (Diaboromon's Fresh form). With the help of Angemon and Angewomon (with T.K. and Kari), Omnimon was able to destroy Diaboromon again, but it turned out to be a trap, as his destruction allowed many more Kuramon to go to the Real World. Things go out of control when the Kuramon in the Real World merge to create a Mega level called Armageddemon, an alternate Mega in Diaboromon's evolutionary line. It is so powerful that neither Omnimon nor Imperialdramon were able to defeat it on their own.

In 2012, after the events of Digimon Adventure: Last Evolution Kizuna, the early adulthood DigiDestined—Daisuke, Miyako, Iori, Takeru Takashi, Hikari, and Ken—must reconcile their new responsibilities with their Digimon partners. But Rui Owada, a mysterious young man, appears, claiming to be the first human to partner with a Digimon–Ukkomon. Could Rui really have been the first-ever DigiDestined?

After years of inactivity, the DigiDestined regroup with their Digimon to save their world, but have the years changed their characters too much?

The DigiDestined go to a nearby hot springs theme park and everyone has a good time, but Joe doesn't show up because he wants to study for his exams. Another infected Digimon, Ogremon, attacks Odaiba. Gomamon runs away from home while Mimi faces problems with the other DigiDestined and her classmates because of her selfish ideas.

After seeing Meicoomon's abrupt transformation and killing of Leomon, Agumon and the other Digimon are kept isolated in Koushiro's office in order to prevent them from infection, but signs of infection begin to appear in Patamon.

Upon arriving at the Digital World after the "reboot", the Digidestined are hunted by a new villain. Meanwhile, Sora is troubled by her partner Digimon's indifference towards her.
