* [[spoiler: When Professor Oak makes you release Pikachu back into the wild. Seriously, try not to cry when the music becomes slow and dreary, and you're forced to look into those big shiny eyes and say "goodbye". Don't worry, [[CrowningMomentOfHeartwarming he comes back.]]]]
* The opening theme can move one to tears.
