S1·E48 The Ultimate Farewell

Humans and digimon all over town invoke the light of their DNAs to answer DATS' plea for help. When the hearts of all humans and digimon become one, Marcus & Agumon activate Burst Mode and deal the decisive punch to destroy Yggdrasil. Yggdrasil concedes defeat, acknowledging that humans and digimon hold potential for growth as long as both stand together. The collision between both worlds stops, and all DATS are reunited with their loved ones in celebration. But not all is joy, as the Digimon must return to help rebuild the Digital World. Each of the DATS digimon spend their last day on Earth together with their human partners. As the day of the parting comes, Marcus arrives telling Agumon he's coming with it to the Digital World. Five years later, Kristy and Keenan attend middle school together; Thomas received the Nobel Prize for curing Relena's illness; Yoshi has become a police officer; and both Marcus and Agumon have became the number one street fighters of the Digital World.
