Saddest episodes in the anime?

[Aamir]

To me, its the last episode of Diamond and Pearl and Lucario and the Mystery of Mew. Watching Piplup and Pikachu crying was really hard to watch and seeing Mew getting sick was sad. What do you think?

 

[Master Cyrus]

Sad day indeed when Sleep Powder becomes an OHKO move.

 

[Supreme Leader Palpitoad]

Sad when Palpitoad never is used. And I agree about last DP episode.

I know! Why even have Palpitoad if it just stays in Juniper's lab?

 

[Yari]

TRio saying their farewells to Arbok and Weezing.

 

[Galar Adventurer]

Bye Bye Butterfree
Pikachu's Goodbye
Charizard's Burning Ambitions
A Scare to Remember
Do I Hear a Ralts?
Evolving Strategies!
Memories Are Made of Bliss!

When Butterfree left Ash. That was pretty sad, and the only sad episode to me. Pikachu's Goodbye wasn't all that sad tbh and all the other episodes don't live up to the sad potential to me. Just Bye Bye Butterfree.
