2x27 - Digimon: Digital Monsters

Paildramon fights Okuwamon while the DigiDestined enter Ken's base, and Ken putting the Crest of Kindness into the energy core is ineffective. However, once Paildramon defeats Okuwamon, he destroys the remains of the base as well. The next day, the DigiDestined meet with Izzy, who explains DNA Digivolution and the original DigiDestined's sacrifice to protect the Digital World years ago.
