Digimon: Digital Monsters

Whamon sacrifices himself while saving WarGreymon, allowing WarGreymon to defeat MetalSeadramon. The DigiDestined proceed to Puppetmon's forest, where he separates them, causing Matt to become overprotective of T.K. Puppetmon forces T.K. to play deadly game of hide-and-seek in exchange for the DigiDestined's safety, but T.K. tricks him and sabotages his control room. After the other DigiDestined regroup and defeat Kiwimon, Matt becomes discouraged seeing that T.K. has escaped without his help.
