Ikkakumon digivolves into Zudomon to help in the battle. Puppetmon tries to get MetalGarurumon to attack the kids like before, but instead, he destroys Puppetmon. Just before Puppetmon disappears for good, he is told that the kids have friends and he doesn't, so he could have never won the battle. Leomon is defeated and is gone. Joe, Mimi, and Ogremon say that they WILL defeat the Dark Masters…or what's left of them anyway.

While the DNA digivolved digimon hold off BlackWarGreymon, Davis gets the idea of moving the last Destiny Stone with the D3s. Instead of moving it, this summons Azulongmon, the digimon that appeared as earlier destiny stones were destroyed. BlackWarGreymon attacks Azulongmon but quickly is shoved off and leaves after learning what his purpose is.
