Tai's Apology and the Emergence of a Virus [0:00]
Tai attempts to send an apology email to Sora, but a system error prevents it. Meanwhile, the other DigiDestined are engaged in various activities: Matt and TK are visiting their grandmother, Joe is in summer school, Sora is upset with Tai, Mimi is in Hawaii, K is at a birthday party, and Izzy discovers a virus attacking a Digi-Egg on his computer. The Digi-Egg hatches, and the new Digimon begins to cause disruptions, including affecting the score of a baseball match.
The Threat Escalates: Keramon's Evolution [1:06]
Izzy informs Tai about the situation, but the Digimon, now identified as Keramon, digivolves and causes more chaos. Tai and Izzy try to contact the other DigiDestined while being contacted by Gennai, who warns them about the threat Keramon poses to the world. Gennai uploads Agumon and Tentomon to the internet to combat Keramon.
Battling Infermon and Global Awareness [2:26]
After failing to reach the other DigiDestined, Agumon and Tentomon engage Keramon, who digivolves into Infermon. Infermon defeats them, and the battle becomes a global spectacle, witnessed by the DigiDestined and a kid named Willis. Tai and Izzy manage to contact Matt and TK, and their Digimon, Gabumon and Patamon, join the fight against Infermon, who is now in America.
WarGreymon and MetalGarurumon vs. Diaboromon [3:11]
Gabumon and Patamon warp digivolve into WarGreymon and MetalGarurumon, respectively, and battle Infermon, who digivolves into Diaboromon. Diaboromon overwhelms them and begins cloning himself, launching two nuclear missiles aimed at Willis and Tai and Izzy. Despite global efforts to intercept the missiles, Diaboromon reroutes them to fall harmlessly in the ocean near Hawaii.
The Digital Fusion: Omnimon's Arrival [4:30]
Izzy theorizes that destroying the original Diaboromon will stop the missiles, but there are over 75,000 clones. WarGreymon and MetalGarurumon are quickly defeated by the clones. Tai's bond with WarGreymon is so strong that Tai himself becomes digital, leading to WarGreymon and MetalGarurumon fusing together to become Omnimon.
Omnimon's Victory and a Looming Threat [6:08]
Omnimon destroys all the clones, revealing the real Diaboromon. Izzy sends all the emails he received to Diaboromon, slowing him down and allowing Omnimon to destroy him. The missiles are disabled, and Sora receives Tai's apology email. However, the video ends with a hint that Willis is about to face a new Digi-battle alone, suggesting a continuation of the story.
