Fan:Digimon 2.5

Digimon 2.5, also called Digimon adventure 3, is a fanfic that focuses on the children of the original digidestined from Digimon Adventure and Digimon Adventure 02. Although certain aspects have been altered, including the children themselves, the fanfic remains loyal to the adults' occupation and timeline.

Differences between Digimon Adventure Epilogue and Digimon 2.5
One of the major differences is that certain pairings have been altered in favor of the author. For example, Sora married Tai instead of Matt, although She retains her fasion designing career and Tai is still a diplomat for the Digital World. Much has happened since then, however; Kari has recently become engaged to TK, having been widowed for six years when her husband died in a fatal car accident. Another difference is that all of the children's Digimon, aside from the Agumon of Dawn, Tai and Sora's only daughter, have different digivolutions than the digimon of their parents (i.e. Instead of digivolving into Stingmon, the Wormmon that belongs to James, the son of Ken and Yolei, digivolves into Kuwagamon, though not the same one the original Digidestined fought).

Story so far
After an encounter with a mysterious girl with a Garurumon X, strange portals called Digital Splits turned up all over Odaiba. Later on, Izzy discovers the Digi-ports are working again. The digidestined have many adventures in both Odaiba and the Digital world. However, things turn for the worst when a mysterious being kills Gennai and steals the Portstone.
