When Worlds Collide

Synopsis
Thrown back to the Human World, Mikey, Angie, and Jeremy return home for some much needed rest, only to discover that their story about traveling to the is universally disbelieved by their family. During the evening, however, a blackout occurs, and Mikey and, who is smaller than usual and unable to be seen by anyone but three, investigate. An unnatural aurora lights the sky, a sign that they take to mean a Digimon is headed their way. A voice then calls for Mikey, who tells him that he had guided him in the world to protect it, and Mikey recognizes it as the one that gave him the Fusion Loader. The voice laments on how it is impossible now and disappears before Mikey can question further.

Mikey spends the next day hanging out with his friends, doing his best to make the most of his time. Suspicious at this generosity, they confront him, and Mikey admits to planning to return to the Digital World with Shoutmon. Angie and Jeremy are more insulted by the implication that he cares more about the Fusion Fighters than they do, but their conversation is interrupted by the same voice speaking.

Omnimon explains how long ago he was a part of an order of knights who defended the Digital World, only for them to be overwhelmed by evil. When they could not stop the sundering, they were transformed into the DigiCards and scattered, with Omnimon being the only one to reach the Human World. There, he waited for one who could hear the DigiMelodies and at last discovered Mikey. The group declares their intent to return, but Omnimon tells them that he only has the strength to return Mikey and Shoutmon. Mikey regrets the decision, but they all acknowledge that someone needs to return, in spite of how vital Angie and Jeremy are to the Fusion Fighters.

Their return is interrupted by, who is more or less unable to be seen by the wider population but is still able to wreak havoc. He is being empowered by the world's digital energy, so the group attempts to draw him into an open space to fight. Neither Shoutmon nor the DigiCard can damage Tactimon, and Tactimon takes the opportunity to capture Angie and Jeremy in his grip. Despite the torture Tactimon puts them through, neither gives in, encouraging Mikey to continue forth no matter what happens to them. Their emotions, courage, and compassion birth a golden light: the light of Digivolution. With this new power, Shoutmon digivolves to. The two Digimon fight in the skies, and in one final clash, OmniShoutmon defeats Tactimon.

With Tactimon's defeat, the Fusion Fighters must part once more. Omnimon uses the last of his power to form a bridge that Mikey and Shoutmon return though, leaving Angie and Jeremy with the powerless DigiCard as they pray for their success. Meanwhile, in the Digital World, Ewan Amano and discussion Ewan's anticipation in challenging Mikey.
