Status of Digimon in 2030
Digimon is now erased from the memories of all but the Digidestined from the past 20 years. Gizmo, however, has recreated it into a fictional franchise in form of Manga and Virtual Pets. He secretly still has access to the Digital World, but has never been back since 2020. He has only told this to Scientists, but only a few know, not even his old friends and partners in Digidestined know. Nobody has been to the Digital World from the Real World since 2020.
The Scientists and The Digital World
The 5 scientests who have been informed of the Digital World act as slightly lower Real-World Moderators. Their project K2 was mysteriously transported into the Digital World.
The New Real World Moderators
The location of the Moderators is unevenly between a rift in the Digital and Real worlds. Tay and Kai now lead them
The Digidestined of this series all own a Digimon Virtual Pet, which become their Digivices. When connected together DNA Digivolution is activated.
Kasaishin 'Saishi' Kinjo & KoroAgumon
Saishi is the son of Tay and Ru-Ru. He is 13 years old and attends the school Tay used to attend. He seems to have inherited his father's football skills. His Digivice is the original Red of the Virtual Pets.
KoroAgumon is the breeding result of Coromon and Agumon. Not much is different about it's appearance except it's a more orangey shade of yellow.
His Digivolution line is:
Botamon --> Koromon --> KoroAgumon --> FiraGreymon --> MeltingMetalGreymon --> ApolloGreymon
He can also Biomerge Digivolve with Kaishi to become Agunigreymon. In one episode, he Armor Digivolves to become an Orange Skinned Flamedramon.
