Digimon Adventure

All of the new DigiDestined (except Davis, who can't fly to the location) sneak into Ken's base. Ken goes into the Dark Whirlpool, even through Wormmon told him not to. Devimon comes out, and T.K. gets mad because of what he did to Patamon long ago and fights Ken. When Ken escapes T.K., he releases Kimeramon on the DigiDestined, and they must flee.
