Becoming Kari's Digimon partner, Gatomon offers his aid in leading the DigiDestined to the Sealed Grounds where the largest fragment containing Millenniumon's essence is located.

But by the time the DigiDestined reached the Sealed Grounds, the Vademon cultists use Sakkakumon's collected data on Agumon to create Machinedramon to fight the children while releasing the miasma from Cloud so Sakakkumon can absorb it and transform into Millenniumon's vessel.

The restored Millenniummon attempts to destroy the entire Digital World, but was defeated by WarGreymon when he receives additional power from his comrades along with the hopes of the friendly Digimon the DigiDestined befriended in their adventure.

Sakurada expressed that the stopping point of the original Adventure series reached on its twentieth anniversary by Last Evolution Kizuna was "sad", but opportune to be able to propose, produce this reboot and deliver it in its current form, terming it as a proper Digimon entry that wasn't for the "children of the past", but for a new generation of children "And in order to introduce it to them, what better way to do it than to start from the beginning one more time with Digimon Adventure?"

For Mitsuka, the overuse of privileged segments in the animation[15] for a TV anime was to show Greymon; and Omnimon looking "cool" from its first fight, in order to leave just as much of a strong impression on those new viewers as on the old ones, a proper action-like depiction of it being uncommon in the previous projects, special circumstances protecting it for very particular moments, this production aimed to depict Omnimon as the miracle that appears after overcoming great difficulties "May each of its appearances in this new TV series be a chance to make it fight powerful enemies, while displaying his strength and a status of crisis saviour".

"The children feel an obligation and a determination to "do something" [...] The central theme of the series' direction is "a person and a creature" in both battle and adventure.
