The DigiDestined struggle to help their partners regain their memories of them.


As the DigiDestined try to reestablish their friendship with their rebooted Digimon partners, they briefly come across Meicoomon, who has retained her memories of Meiko despite the reboot. While the others seem to get along well with their partners, who evolve back into rookie form, Sora has trouble reconnecting with Biyomon, who appears hostile towards her. Later that night, as Tai and Matt try to help Sora with her worries, they are suddenly attacked by Machinedramon, whose attack spreads the DigiDestined and Digimon across the Digital World. Meanwhile, Nishijima looks into the whereabouts of Himekawa's secret files and remembers how she wanted to reboot the Digital World to revive her own deceased partner Digimon who was unable to recompose into a Digi-Egg after death. He is then approached by a Digimon named Hackmon who relays a message from Homeostasis warning him about King Drasil who has gotten its hands on Gennai and targets Meicoomon for something known as "Libra".

Sora and Biyomon end up in the desert, where they come across Meiko, who came to the Digital World to search for Meicoomon. When Meicoomon attacks them out of fear of abandonment, Meiko manages to stand up and calm her down. Just then, they are attacked by the Mysterious Man that had disguised himself as Ken, who attempts to capture Meicoomon and Sora's Digivice. As the other DigiDestined all come to their aid, the Mysterious Man shows his true form and reveals that the reboot was all part of Kind Drasil's plan to create a new world order submission both world in one rule. Where humans and Digimon no longer interact with each other and the enslavement of both world into isolation for the cabal system. In order do so, he requiring DigiDestined soul alongside with their Digimon partner. Afterwards, He sends Machinedramon and MetalSeadramon after them. Elsewhere, Himekawa finds her partner Digimon, Tapirmon, but is shocked when he doesn't remember her. As Tai, Matt and Kari manage to strengthen their bonds enough to digivolve their partners and defeat MetalSeadramon, Sora risks her life to protect Biyomon from Machinedramon, digivolving her into her Mega form, Phoenixmon, who defeats Machinedramon alongside Seraphimon and HerculesKabuterimon. Meanwhile, Mysterious Man attacks Meiko, sending Meicoomon into a fury and Mysterious Man laughing for his enjoyment of her suffering.

Other notes

Animation errors

  • When Patamon sleeps, his legs are incorrectly colored the same color as orange.
  • In the English version, they used AtlurKabuterimon during Kabuterimon digivolve to MegaKabuterimon again since Confession.

Dubbing changes

  • Gennai is pronounced with a soft G (as it originally was during the first two seasons) despite it being pronounced with a hard G in Reunion (Original pronunciation in the Japanese version)
  • Hououmon is called Phoenixmon in the dub. Additionally, Phoenixmon never shouted her Starlight Explosion attack during the battle with Machinedramon.

Miscellaneous trivia

  • At one point, Sora was smashed against an ice wall by Machinedramon. She survived without any lasting harm, despite the fact that humans are nowhere near as durable as Digimon are.
