The children make their Digimon evolve into their Ultimate and Mega forms, and they are brought back to the dimension where Apocalymon lives. The children and their Digimon begin to attack Apocalymon. It seems they have defeated the evil Digimon, but with his dying breath he threatens to take the whole world with him. Apocalymon says that his ultimate attack, Ultimate Destroyer, will destroy the entire digital world. But with the power of the children's digivices they seal the enemy, saving the Digiworld from destruction. Although the children wish to stay longer in the Digiworld, Gennai tells them that unless they return home now they will be erased during the reconstruction of the Digiworld. Saying goodbye to their Digimon, the children returned home, but they promise to return back someday and somehow.
