Digimon Adventure

Synopsis

Whamon saves WarGreymon by ramming him, but is mortally wounded by MetalSeadramon's River of Power in response. WarGreymon, enraged, destroys MetalSeadramon with his Great Tornado attack. Whamon succumbs to his wounds and dies, but begs the Digidestined to save the world. After watching the Net Ocean dissolve with MetalSeadramon's death, the kids then go into a forest which is part of Puppetmon's domain. Puppetmon continually taunt the group while splitting them up. From there, Puppetmon captures Matt and offers T.K. his older brother's freedom in return for a deadly game of hide and seek. Luckily, T.K. manages to play on Puppetmon's friendship issues to sabotage his control room as the other DigiDestined regroup and defeat Puppetmon's minion Kiwimon despite Matt's need to find his brother. But when T.K. rejoins the others, a disillusioned Matt walks off while Puppetmon vows revenge.
