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.

While Puppetmon orders Garbagemon to attack the DigiDestined, Matt withdraws and meets Cherrymon. Cherrymon convinces him to defeat Tai, who he claims is the source of Matt's self-doubt. Matt returns to the DigiDestined and demands Tai to fight him, while Cherrymon is killed by Puppetmon after warning him not to underestimate an advantage that the DigiDestined have over him.

Tension runs high as a fight breaks out between Matt, Tai, and their Digimon. Kari's body is taken over a strange entity, who explains why the DigiDestined were chosen to save the Digital World. Uncertain, Matt leaves the group. Upset from the conflict, Mimi leaves as well, with Joe accompanying her. The rest of the DigiDestined continue their journey to fight the Dark Masters.

Joe and Mimi rescue an injured Ogremon, while Etemon returns as MetalEtemon to take revenge on them. Meanwhile, Tai's group infiltrate Puppetmon's mansion with the help of two of his playmates, keeping Puppetmon at bay with his own cannon.

SaberLemon rescues Joe and Mimi, but they are found by MetalEtemon again. He destroys MetalEtemon with Joe and Zudomon's help but dies from a fatal wound from protecting Mimi. At the same time, Puppetmon is defeated by the DigiDestined and destroyed by Matt and MetalGarurumon upon escaping. Recognizing Puppetmon's defeat and Leomon's sacrifice, Mimi regains her will to fight as she and Joe decide to gather more reinforcements while Tai's group fights the remaining Dark Masters.

Kari falls ill, and Tai becomes nearly hysterical in his attempts to help her. Machinedramon attacks them in a mechanical city under his control, and the group is separated.
