Present-day. Digiworld. Dark Ocean. Daemon is furious.

"How could those digidestined brats beat me? They may have thought they saw the last of me, but they are wrong. Luckily I've gained the power of time travel. I think I'll go into the past to when Myotismon was attacking." said Daemon.

Daemon slips through a portal, and vanishes.

Four years ago...

Real world. Daemon appears invisible. He sends a blast of black energy at Ken's parents, who decide to move to Obdavia.

Obdaiva. Ken and his family move into the apartment where Tai, Kari, Mimi, and Sora live. Tk, Matt, Joe, and Izzy live in houses.

Next day. Myotismon kidnaps children. Kari, her parents, Ken, his parents, Mimi, her parents, Sora, Sora's mom, Biyomon, and Palmon are among them. Tai, and Greymon go after them. Sora, Birdramon, and Lillymon escape before Tai arrives. Izzy, Izzy's parents, Matt's dad, Matt, and Sora regroup at the television station.

Convention station. Ken's digivice glows, and a computer shines out Wormon and the Crest of Kindness. Ken places the crest on, and Wormon tells him who he is. Kari and Mimi run over to Ken. Kari pulls out her digivice from her pocket when she sees Mimi's and Ken's.

"So there are nine digidestined." said a voice.

Mimi, Ken, and Kari turn around to see Demi-devumon, Phantom, and Bakemon. They take the digidestined, and Wormon to Myotismon.

Pier. Tk, Patamon, and Joe ride Ikakumon through the sea. Mega Sedramon attacks. Joe and Tk fall off. Joe puts Tk onto a floating board, and sinks. Joe's crest glows. Ikakumon digivolves to Zudomon, and destroys Mega Sedramon. He rescues Joe, Tk, and Patamon from the river, along with Wizardmon, who shows them the Crest of Light, and says that Kari is the eighth digidestined, and that Gatomon is the eighth digimon. The group breaks through the mist.

TV studio. Joe, Tk, Zudomon, Patamon, and Wizardmon meet the group. He unfreezes Wizardmon. Joe and Tk tell the others that Wizardmon is on our side, and that he has Kari's crest. Matt and Sora are skeptical at first, until Wizardmon shows them the Crest of Light.

"Where's Kari?" asked Wizardmon.

"He's got her." said Matt.

Convention center. Tai and Greymon arrive to discover everyone asleep. They defeat all the digimon there, and run up the stairs to see Myotismon and Demi-devumon flying away with Gatomon, Kari, Mimi, Ken, Wormon, and Demi-devumon.

"NO! KARI! MIMI!" yelled Tai.

"We better get to the TV station." said Greymon.

"Right." said Tai.

"Greymon digivolve to Metal Greymon!"

Metal Greymon flies out after Myotismon and the captive digidestined and digimon.

TV station. Myotismon and his group arrive. Tai and Metal Greymon arrive, and Myotismon flies onto a rooftop with the three digidestined. The remaining digidestined get to the opposite roof.

"Wormon digivolve to Stingmon!"

"Tentomon digivolve to Kabuterimon!"

"Kabuterimon digivolve to Mega Kabuterimon!"

"Gatomon digivolve to Angewomon!"

"Patamon digivolve to Angemon!"

"Birdramon digivolve to Garudamon!"

"Gabumon digivolve to Garurumon!"

"Garurumon digivolve to Were Garurumon!"

The digimon defeat the remaining forces of Myotismon, and regroup to attack.

"Heaven's Charge!" said Angewomon, firing a portal above her.

"Give your power to Angewomon! Wing Blade!" said Garudamon.

"Giga Blasters!" said Metal Greymon.

"Metal Wolf Claw!" said Were Garurumon.

"Horn Buster!" said Mega Kabuterimon!

"Flower Cannon!" said Lillymon.

"Super Thunder Strike!" said Zudomon.

"Hand of Faith!" said Angemon.

"Spiking Strike!" said Stingmon.

The blasts fly into the portal.

"Celestial Arrow!" said Angewomon.

The blast from the portal turns into an energy arrow, and she fires it Myotismon. Phantom is killed, and Myotismon also dies. The nine digidestined and digimon regroup at the bottom. The digimon dedigivolve to Koromon, Tsunamon, Yokomon, Motimon, Bukemon, Tanemon, Patamon, Salamon, and Wormon. The group vows to stick together. Kari, Tk, and Ken look up.

"The mist isn't going away." said Kari.

Everyone looks up, and sees the mist staying.

"Then is Myotismon still alive?" asked Joe.

"If he is, then the nine of us will be ready for him." said Tai.
